Upgrading, Rebooting, and Resyncing Your ATA Device The istration web server s upgrading, rebooting, and resyncing functions through special URLs. privilege is needed for these functions.

Upgrade URL The Upgrade URL lets you upgrade the ATA device to the firmware specified by the URL, which can identify either a TFTP or HTTP server.

NOTE If the value of the Upgrade Enable parameter in the Provisioning page is No, you

cannot upgrade the ATA device even if the web page indicates otherwise. The syntax of the Upgrade URL is as follows: http://spa-ip-addr//upgrade?[protocol://][server-name[:port]][/ firmware-pathname]

Both HTTP and TFTP are ed for the upgrade operation.


38

If no protocol is specified, TFTP is assumed. If no server-name is specified, the host that requests the URL is used as server-name. If no port specified, the default port of the protocol is used. (69 for TFTP or 80 for HTTP) The firmware-pathname is typically the file name of the binary located in a directory on the TFTP or HTTP server. If no firmware-pathname is specified, / spa.bin is assumed, as in the following example: http://192.168.2.217//upgrade?tftp://192.168.2.251/spa.bin

Resync URL The Resync URL lets you force the ATA device to do a resync to a profile specified in the URL, which can identify either a TFTP, HTTP, or HTTPS server. The syntax of the Resync URL is as follows: http://spa-ip-addr//resync?[[protocol://][server-name[:port]]/profilepathname]

NOTE The SPA resyncs only when it is idle.

If no parameter follows /resync?, the Profile Rule setting from the Provisioning page is used. If no protocol is specified, TFTP is assumed. If no server-name is specified, the host that requests the URL is used as server-name. If no port is specified, the default port is used (69 for TFTP, 80 for HTTP, and 443 for HTTPS). The profile-path is the path to the new profile with which to resync, for example: http://192.168.2.217/resync?tftp://192.168.2.251/spaconf.cfg

Reboot URL The Reboot URL lets you reboot the ATA device. The Reboot URL is as follows: http://spa-ip-addr//reboot

NOTE The ATA device reboots only when it is idle.

Provisioning Your ATA Device This section describes the provisioning functionality of the ATA device. This section includes the following topics: •

“Provisioning Capabilities” section on page 40

•

“Configuration Profile” section on page 41

For detailed information about provisioning your ATA device, refer to the SPA Provisioning Guide.

Provisioning Capabilities The ATA device provides for secure provisioning and remote upgrade. Provisioning is achieved through configuration profiles transferred to the device via TFTP, HTTP, or HTTPS. To configure Provisioning, go to Provisioning tab in the istration web server. The ATA device can be configured to automatically resync its internal configuration state to a remote profile periodically and on power up. The automatic resyncs are controlled by configuring the desired profile URL into the device. The ATA device accepts profiles in XML format, or alternatively in a proprietary binary format, which is generated by a profile compiler tool available from Cisco. Find the Profiler Compiler for your ATA at http://www.cisco.com/web/partners/ sell/smb/products/voice_and_conferencing.html#~vc_technical_resources. The ATA device s up to 256-bit symmetric key encryption of profiles. For the initial transfer of the profile encryption key (initial provisioning stage), the ATA device can receive a profile from an encrypted channel (HTTPS), or it can resync to a binary profile generated by the Cisco-supplied profile compiler. In the latter case, the profile compiler can encrypt the profile specifically for the target ATA device, without requiring an explicit key exchange. Remote firmware upgrade is achieved via TFTP or HTTP (firmware upgrades using HTTPS are not ed). Remote upgrades are controlled by configuring the desired firmware image URL into the ATA device via a remote profile resync. For further information about remote provisioning refer to the SPA Provisioning Guide.


40

Basic istration and Configuration Provisioning Your ATA Device

Configuration Profile The ATA configuration profile can be either an XML file or a binary file with a proprietary format. The XML file consists of a series of elements (one per configuration parameter), encapsulated within the element tags … . The encapsulated elements specify values for individual parameters. Here is an example of a valid XML profile: <_wd rel="nofollow"> some secret Yes

Binary format profiles contain ATA parameter values and access permissions for the parameters. By convention, the profile uses the extension .cfg (for example, spa2102.cfg). The Profile Compiler (SPC) tool compiles a plain-text file containing parameter-value pairs into a properly formatted and encrypted .cfg file. The SPC tool is available for the Win32 environment and Linux-i386-elf environment. Requests for SPC tools compiled on other platforms are evaluated on a case-bycase basis. Please your sales representative for further information about obtaining the SPC tool. The syntax of the plain-text file accepted by the profile compiler is a series of parameter-value pairs, with the value in double quotes. Each parameter-value pair is followed by a semicolon. Here is an example of a valid text source profile for input to the SPC tool: _wd “some secret”; Upgrade_Enable “Yes”;

Refer to the SPA Provisioning Guide for further details. The names of parameters in XML profiles can generally be inferred from the ATA configuration Web pages, by substituting underscores (_) for spaces and other control characters. Further, to distinguish between Lines 1, 2, 3, and 4, corresponding parameter names are augmented by the strings _1_, _2_, _3_, and _4_. For example, Line 1 Proxy is named Proxy_1_ in XML profiles. Parameters in the case of source text files for the SPC tool are similarly named, except that to differentiate Line 1, 2, 3, and 4, the appended strings ([1], [2], [3], or [4]) are used. For example, the Line 1 Proxy is named Proxy[1] in source text profiles for input to the SPC.

3 Configuring Your System for ITSP Interoperability

This chapter provides configuration details to help you to ensure that your infrastructure properly s voice services.

“Network Address Translation (NAT) and Voice over IP (VoIP),” on page 42

•

“Firewalls and SIP,” on page 48

•

“Configuring SIP Timer Values,” on page 48

Network Address Translation (NAT) and Voice over IP (VoIP) NAT is a function that allows multiple devices to share the same public, routable, IP address to establish connections over the Internet. NAT is present in many broadband access devices to translate public and private IP addresses. To enable VoIP to co-exist with NAT, some form of NAT traversal is required. Some ITSPs provide NAT traversal, but some do not. If your ITSP does not provide NAT traversal, you have several options.

NAT Mapping with Session Border Controller It is strongly recommended that you choose an ITSP that s NAT mapping through a Session Border Controller. With NAT mapping provided by the ITSP, you have more choices in selecting a router.

NAT Mapping with SIP-ALG Router If the ITSP network does not provide a Session Border Controller functionality, you can achieve NAT mapping by using a router that has a SIP ALG (Application Layer Gateway). The WRV200 router is recommended for this purpose, although any router with a SIP-ALG can be used. By using a SIP-ALG router, you have more choices in selecting an ITSP.

Configuring NAT Mapping with a Static IP Address If the ITSP network does not provide a Session Border Controller functionality, and if other requirements are met, you can configure NAT mapping to ensure interoperability with the ITSP. Requirements:

•

You must have an external (public) IP address that is static.

•

The NAT mechanism used in the router must be symmetric. See “Determining the Router’s NAT Mechanism,” on page 47.

•

The LAN switch must be configured to enable Spanning Tree Protocol and Port Fast on the ports to which the SPA devices are connected.

NOTE Use NAT mapping only if the ITSP network does not provide a Session Border

Controller functionality. STEP 1 Connect to the istration web server, and choose access with

Advanced settings. STEP 2 Click Voice tab > SIP.


43

STEP 3 Scroll down to the NAT Parameters section, and then enter the following

settings to static mapping to your public IP address:

•

Handle VIA received, Insert VIA received, Substitute VIA Addr: yes

•

Handle VIA rport, Insert VIA rport, Send Resp To Src Port: yes

•

EXT IP: Enter the public IP address for your router. Voice tab > SIP: NAT Parameters

STEP 4 Click Voice tab > Line N, where N represents the line interface number. STEP 5 Scroll down to the NAT Settings section.

•

NAT Mapping Enable: Choose YES.

•

NAT Keep Alive Enable: Choose YES (optional). Voice tab > Line N > NAT Settings

STEP 6 Click Submit All Changes.

NOTE You also need to configure the firewall settings on your router to allow SIP

traffic. See “Firewalls and SIP,” on page 48.


44


3

Configuring NAT Mapping with STUN If the ITSP network does not provide a Session Border Controller functionality, and if other requirements are met, it is possible to use STUN as a mechanism to discover the NAT mapping. This option is considered a practice of last resort and should be used only if the other methods are unavailable. Requirements:

•

STUN is a viable option only if your router uses asymmetric NAT. See “Determining the Router’s NAT Mechanism,” on page 47.

•

You must have a computer running STUN server software.

•

The LAN switch must be configured to enable Spanning Tree Protocol and Port Fast on the ports to which the SPA devices are connected.

NOTE Use NAT mapping only if the ITSP network does not provide a Session Border

Controller functionality. STEP 1 Connect to the istration web server, and choose access with

Advanced settings. STEP 2 Click Voice tab > SIP. STEP 3 Scroll down to the NAT Parameters section, and then enter the following

settings to enable and the STUN server settings:

•

Handle VIA received: yes

•

Handle VIA rport: yes

•

Insert VIA received: yes

•

Insert VIA rport: yes

•

Substitute VIA Addr: yes

•

Send Resp To Src Port: yes

•

STUN Enable: Choose yes.

•

STUN Server: Enter the IP address for your STUN server.

Voice tab > SIP > NAT Parameters

STEP 4 Click Voice tab > Line N, where N is the number of the line interface. STEP 5 Scroll down to the NAT Settings section.

•

NAT Mapping Enable: Choose yes.

•

NAT Keep Alive Enable: Choose yes (optional). Voice tab > Line N > NAT Settings

NOTE Your ITSP may require the SPA device to send NAT keep alive messages to

keep the NAT ports open permanently. Check with your ITSP to determine the requirements. STEP 6 Click Submit All Changes.

NOTE You also need to configure the firewall settings on your router to allow SIP

traffic. See “Firewalls and SIP,” on page 48.


46


3

Determining the Router’s NAT Mechanism STUN does not work on routers with symmetric NAT. With symmetric NAT, IP addresses are mapped from one internal IP address and port to one external, routable destination IP address and port. If another packet is sent from the same source IP address and port to a different destination, then a different IP address and port number combination is used. This method is restrictive because an external host can send a packet to a particular port on the internal host only if the internal host first sent a packet from that port to the external host.

NOTE This procedure assumes that a syslog server is configured and is ready to receive

syslog messages. STEP 1 Make sure you do not have firewall running on your PC that could block the syslog

port (port 514 by default). STEP 2 Connect to the istration web server, and choose access with

Advanced settings. STEP 3 To enable debugging, complete the following tasks:

a. Click Voice tab > System. b. In the Debug Server field, enter the IP address of your syslog server. This address and port number must be reachable from the SPA9000. c. From the Debug level drop-down list, choose 3. STEP 4 To collect information about the type of NAT your router is using, complete the

following tasks: a. Click Voice tab > SIP. b. Scroll down to the NAT Parameters section. c. From the STUN Test Enable field, choose yes. STEP 5 To enable SIP signalling, complete the following task:

a. Click Voice tab > Line N, where N represents the line interface number. b. In the SIP Settings section, choose full from the SIP Debug Option field.


47

Configuring Your System for ITSP Interoperability Firewalls and SIP

3

STEP 6 Click Submit All Changes. STEP 7 View the syslog messages to determine whether your network uses symmetric

NAT. Look for a warning header in the messages, such as Warning: 399 spa "Full Cone NAT Detected.”

Firewalls and SIP To enable SIP requests and responses to be exchanged with the SIP proxy at the ITSP, you must ensure that your firewall allows both SIP and RTP unimpeded access to the Internet.

•

•

Make sure that the following ports are not blocked: •

SIP ports—UDP port 5060 through 5063, which are used for the ITSP line interfaces

•

RTP ports—16384 to 16482

Also disable SPI (Stateful Packet Inspection) if this function exists on your firewall.

Configuring SIP Timer Values The default timer values should be adequate in most circumstances. However, you can adjust the SIP timer values as needed to ensure interoperability with your ISTP. For example, if SIP requests are returned with an “invalid certificate” message, you may need to enter a longer SIP T1 retry value. To view the default settings or to make changes, open the Voice > SIP page, and scroll down to the SIP Timer Values section. For field descriptions, see ”SIP Timer Values (sec) section,” on page 124 of Appendix B.

Configuring Voice Services Silence Suppression and Comfort Noise Generation

4

Silence Suppression and Comfort Noise Generation Voice Activity Detection (VAD) with Silence Suppression is a means of increasing the number of calls ed by the network by reducing the required bandwidth for a single call. VAD uses a sophisticated algorithm to distinguish between speech and non-speech signals. Based on the current and past statistics, the VAD algorithm decides whether or not speech is present. If the VAD algorithm decides speech is not present, the silence suppression and comfort noise generation is activated. This is accomplished by removing and not transmitting the natural silence that occurs in normal two-way connection. The IP bandwidth is used only when someone is speaking. During the silent periods of a telephone call, additional bandwidth is available for other voice calls or data traffic because the silence packets are not being transmitted across the network. Comfort Noise Generation provides artificially-generated background white noise (sounds), designed to reassure callers that their calls are still connected during silent periods. If Comfort Noise Generation is not used, the caller may think the call has been disconnected because of the “dead silence” periods created by the VAD and Silence Suppression feature. Silence suppression is configured in the Line and PSTN Line tabs. See “ATA Routing Field Reference,” on page 100.

Configuring Dial Plans

Configuring Dial Plans Dial plans determine how the digits are interpreted and transmitted. They also determine whether the dialed number is accepted or rejected. You can use a dial plan to facilitate dialing or to block certain types of calls such as long distance or international. This section includes information that you need to understand dial plans, as well as procedures for configuring your own dial plans. This section includes the following topics:

•

“About Dial Plans,” on page 56

•

“Editing Dial Plans,” on page 65

About Dial Plans This section provides information to help you understand how dial plans are implemented. Refer to the following topics:

•

Digit Sequences A dial plan contains a series of digit sequences, separated by the | character. The entire collection of sequences is enclosed within parentheses. Each digit sequence within the dial plan consists of a series of elements, which are individually matched to the keys that the presses.

NOTE White space is ignored, but may be used for readability.

0 1 2 3 4 5 6 7 8 9 0 * #

Enter any of these characters to represent a key that the must press on the phone keypad.

x

Enter x to represent any character on the phone keypad.

[sequence]

Enter characters within square brackets to create a list of accepted key presses. The can press any one of the keys in the list.

. (period)

•

Numeric range For example, you would enter [2-9] to allow the to press any one digit from 2 through 9.

•

Numeric range with other characters For example, you would enter [35-8*] to allow the to press 3, 5, 6, 7, 8, or *.

Enter a period for element repetition. The dial plan accepts 0 or more entries of the digit. For example, 01. allows s to enter 0, 01, 011, 0111, and so on. For sequence substitution, use this format to indicate that certain dialed digits are replaced by other characters when the sequence is transmitted. The dialed digits can be zero or more characters. EXAMPLE 1: <8:1650>xxxxxxx When the presses 8 followed by a sevendigit number, the system automatically replaces the dialed 8 with 1650. If the dials 85550112, the system transmits 16505550112. EXAMPLE 2: <:1>xxxxxxxxxx In this example, no digits are replaced. When the enters a 10-digit string of numbers, the number 1 is added at the beginning of the sequence. If the dials 9725550112, the system transmits 19725550112

Digit Sequence

Function

,

For an intersequence tone, enter a comma between digits to play an “outside line” dial tone after a -entered sequence.

(comma)

EXAMPLE: 9, 1xxxxxxxxxx An “outside line” dial tone is sounded after the presses 9, and the tone continues until the presses 1. ! (exclamation point)

For number barring, enter an exclamation point to prohibit a dial sequence pattern. EXAMPLE: 1900xxxxxxx! The system rejects any 11-digit sequence that begins with 1900.

*xx

Enter an asterisk to allow the to enter a 2digit star code.

S0 or L0

For Interdigit Timer Master Override, enter S0 to reduce the short inter-digit timer to 0 seconds, or enter L0 to reduce the long inter-digit timer to 0 seconds.

P

For a pause, enter P followed by a number and a space. The duration of the pause is the specified number of seconds. This feature is typically used for implementation of a hot line and warm line, with 0 delay for the hot line and a non-zero delay for a warm line. EXAMPLE: P5

NOTE The SPA implicitly appends the vertical code sequences entered in the regional

parameter settings to the end of the dial plan. Likewise, if Enable_IP_Dialing is enabled, then IP dialing is also accepted on the associated line.

Digit Sequence Examples The following examples show digit sequences that you can enter in a dial plan. In a complete dial plan entry, sequences are separated by a pipe character (|), and the entire set of sequences is enclosed within parentheses. EXAMPLE: ( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx | 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )

•

Extensions on your system EXAMPLE: ( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx | 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 ) [1-8]xx Allows a dial any three-digit number that starts with the digits 1

through 8. If your system uses four-digit extensions, you would instead enter the following string: [1-8]xxx

•

Local dialing with seven-digit number EXAMPLE: ( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx | 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]111) 9, xxxxxxx After a presses 9, an external dial tone sounds. The can enter any seven-digit number, as in a local call.

•

Local dialing with 3-digit area code and a 7-digit local number EXAMPLE: ( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx | 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 ) 9, <:1>[2-9]xxxxxxxxx This example is useful where a local area code is required.

After a presses 9, an external dial tone sounds. The must enter a 10digit number that begins with a digit 2 through 9. The system automatically inserts the 1 prefix before transmitting the number to the carrier.

•

Local dialing with an automatically inserted 3-digit area code EXAMPLE: ( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx | 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )


59

8, <:1212>xxxxxxx This is example is useful where a local area code is required

by the carrier but the majority of calls go to one area code. After the presses 8, an external dial tone sounds. The can enter any seven-digit number. The system automatically inserts the 1 prefix and the 212 area code before transmitting the number to the carrier.

•

U.S. long distance dialing EXAMPLE: ( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx | 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 ) 9, 1 [2-9] xxxxxxxxx After the presses 9, an external dial tone sounds. The can enter any 11-digit number that starts with 1 and is followed by a digit 2 through 9.

•

Blocked number EXAMPLE: ( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx | 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 ) 9, 1 900 xxxxxxx ! This digit sequence is useful if you want to prevent s from

dialing numbers that are associated with high tolls or inappropriate content, such as 1-900 numbers in the U.S.. After the press 9, an external dial tone sounds. If the enters an 11-digit number that starts with the digits 1900, the call is rejected.

•

U.S. international dialing EXAMPLE: ( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx | 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 ) 9, 011xxxxxx. After the presses 9, an external dial tone sounds. The can

enter any number that starts with 011, as in an international call from the U.S.

•

Informational numbers EXAMPLE: ( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxx | 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 ) 0 | [49]11 This example includes two digit sequences, separated by the pipe character. The first sequence allows a to dial 0 for an operator. The second sequence allows the to enter 411 for local information or 911 for emergency services.

Acceptance and Transmission the Dialed Digits When a dials a series of digits, each sequence in the dial plan is tested as a possible match. The matching sequences form a set of candidate digit sequences. As more digits are entered by the , the set of candidates diminishes until only one or none are valid. When a terminating event occurs, the SPA9000 either accepts the -dialed sequence and initiates a call, or else rejects the sequence as invalid. The hears the reorder (fast busy) tone if the dialed sequence is invalid. The following table explains how terminating events are processed. Terminating Event

Processing

The dialed digits do not match any sequence in the dial plan.

The number is rejected.

The dialed digits exactly match one sequence in the dial plan.

•

If the sequence is allowed by the dial plan, the number is accepted and is transmitted according to the dial plan.

•

If the sequence is blocked by the dial plan, the number is rejected.

A timeout occurs.

The presses the # key or the dial softkey on the phone display.


The number is rejected if the dialed digits are not matched to a digit sequence in the dial plan within the time specified by the applicable interdigit timer. •

The Interdigit Long Timer applies when the dialed digits do not match any digit sequence in the dial plan. The default value is 10 seconds.

•

The Interdigit Short Timer applies when the dialed digits match one or more candidate sequences in the dial plan. The default value is 3 seconds.

•

If the sequence is complete and is allowed by the dial plan, the number is accepted and is transmitted according to the dial plan.

•

If the sequence is incomplete or is blocked by the dial plan, the number is rejected.

Dial Plan Timer (Off-Hook Timer) You can think of the Dial Plan Timer as “the off-hook timer.” This timer starts counting when the phone goes off hook. If no digits are dialed within the specified number of seconds, the timer expires and the null entry is evaluated. Unless you have a special dial plan string to allow a null entry, the call is rejected. The default value is 5.

Syntax for the Dial Plan Timer SYNTAX: (Ps<:n> | dial plan )

•

s: The number of seconds; if no number is entered after P, the default timer of 5 seconds applies.

•

n: (optional): The number to transmit automatically when the timer expires; you can enter an extension number or a DID number. No wildcard characters are allowed because the number will be transmitted as shown. If you omit the number substitution, <:n>, then the hears a reorder (fast busy) tone after the specified number of seconds.

Examples for the Dial Plan Timer

•

Allow more time for s to start dialing after taking a phone off hook. EXAMPLE: (P9 | (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxx | 9,8,011xx. | 9,8,xx.|[1-8]xx) P9 After taking a phone off hook, a has 9 seconds to begin dialing. If no

digits are pressed within 9 seconds, the hears a reorder (fast busy) tone. By setting a longer timer, you allow more time for s to enter the digits.

•

Create a hotline for all sequences on the System Dial Plan EXAMPLE: (P9<:23> | (9,8<:1408>[2-9]xxxxxx | 9,8,1[29]xxxxxxxxx | 9,8,011xx. | 9,8,xx.|[1-8]xx) P9<:23> After taking the phone off hook, a has 9 seconds to begin dialing. If no digits are pressed within 9 seconds, the call is transmitted automatically to extension 23.

•

Create a hotline on a line button for an extension EXAMPLE: ( P0 <:1000>) With the timer set to 0 seconds, the call is transmitted automatically to the specified extension when the phone goes off hook. Enter this sequence in the Phone Dial Plan for Ext 2 or higher on a client station.

Interdigit Long Timer (Incomplete Entry Timer) You can think of this timer as the “incomplete entry” timer. This timer measures the interval between dialed digits. It applies as long as the dialed digits do not match any digit sequences in the dial plan. Unless the enters another digit within the specified number of seconds, the entry is evaluated as incomplete, and the call is rejected. The default value is 10 seconds.

NOTE This section explains how to edit a timer as part of a dial plan. Alternatively, you can

modify the Control Timer that controls the default interdigit timers for all calls. See “Resetting the Control Timers,” on page 65.

Syntax for the Interdigit Long Timer SYNTAX: L:s, ( dial plan )

•

s: The number of seconds; if no number is entered after L:, the default timer of 5 seconds applies.

•

Note that the timer sequence appears to the left of the initial parenthesis for the dial plan.

Example for the Interdigit Long Timer EXAMPLE: L:15, (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxx | 9,8,011xx. | 9,8,xx.|[1-8]xx) L:15, This dial plan allows the to pause for up to 15 seconds between digits

before the Interdigit Long Timer expires. This setting is especially helpful to s such as sales people, who are reading the numbers from business cards and other printed materials while dialing.

Interdigit Short Timer (Complete Entry Timer) You can think of this timer as the “complete entry” timer. This timer measures the interval between dialed digits. It applies when the dialed digits match at least one digit sequence in the dial plan. Unless the enters another digit within the specified number of seconds, the entry is evaluated. If it is valid, the call proceeds. If it is invalid, the call is rejected. The default value is 3 seconds.

Syntax for the Interdigit Short Timer

•

SYNTAX 1: S:s, ( dial plan ) Use this syntax to apply the new setting to the entire dial plan within the parentheses.

•

SYNTAX 2: sequence Ss Use this syntax to apply the new setting to a particular dialing sequence. s: The number of seconds; if no number is entered after S, the default timer of 5 seconds applies.

Examples for the Interdigit Short Timer

•

Set the timer for the entire dial plan. EXAMPLE: S:6, (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxx | 9,8,011xx. | 9,8,xx.|[1-8]xx) S:6, While entering a number with the phone off hook, a can pause for up

to 15 seconds between digits before the Interdigit Short Timer expires. This setting is especially helpful to s such as sales people, who are reading the numbers from business cards and other printed materials while dialing.

•

Set an instant timer for a particular sequence within the dial plan. EXAMPLE: (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxxS0 | 9,8,011xx. | 9,8,xx.|[1-8]xx) 9,8,1[2-9]xxxxxxxxxS0 With the timer set to 0, the call is transmitted automatically

when the dials the final digit in the sequence.

Secure Call Implementation

Secure Call Implementation This section describes secure call implementation with the ATA device . It includes the following topics:

•

“Enabling Secure Calls” section on page 66

•

“Secure Call Details” section on page 67

•

“Using a Mini-Certificate” section on page 68

•

“Generating a Mini Certificate” section on page 68

NOTE This is an advanced topic meant for experience installers. See also the LVS

Provisioning Guide.

Enabling Secure Calls A secure call is established in two stages. The first stage is no different from normal call setup. The second stage starts after the call is established in the normal way with both sides ready to stream RTP packets. In the second stage, the two parties exchange information to determine if the current call can switch over to the secure mode. The information is transported by base64 encoding embedded in the message body of SIP INFO requests, and responses using a proprietary format. If the second stage is successful, the ATA device plays a special Secure Call Indication Tone for a short time to indicate to both parties that the call is secured and that RTP traffic in both directions is being encrypted. If the has a phone that s call waiting caller ID (CIDCW) and that service is enabled, the CID will be updated with the information extracted from the Mini-Certificate received from the remote party. The Name field of the CID will be prepended with a ‘$’ symbol. Both parties can the name and number to ensure the identity of the remote party. The g agent is implicit and must be the same for all ATAs that communicate securely with each other. The public key of the g agent is pre-configured into the ATA device by the and is used by the ATA device to the Mini-Certificate of its peer. The Mini-Certificate is valid if it has not expired, and it has a valid signature.


66

4


The ATA device can be configured so that, by default, all outbound calls are either secure or not secure. If secure by default, the has the option to disable security when making a call by dialing *19 before dialing the target number. If not secure by default, the can make a secure outbound call by dialing *18 before dialing the target number. However, the cannot force inbound calls to be secure or not secure; that depends on whether the caller has security enabled or not. The ATA device will not switch to secure mode if the CID of the called party from its Mini-Certificate does not agree with the -id used in making the outbound call. The ATA device performs this check after receiving the Mini-Certificate of the called party

Secure Call Details Looking at the second stage of setting up a secure call in greater detail, this stage can be further divided into two steps. STEP 1 The caller sends a “Caller Hello” message (base64 encoded and embedded in the

message body of a SIP INFO request) to the called party with the following information:

•

Message ID (4B)

•

Version and flags (4B)

•

SSRC of the encrypted stream (4B)

•

Mini-Certificate (252B)

Upon receiving the Caller Hello, the called party responds with a Callee Hello message (base64 encoded and embedded in the message body of a SIP response to the caller’s INFO request) with similar information, if the Caller Hello message is valid. The caller then examines the Callee Hello and proceeds to the next step if the message is valid. STEP 2 The caller sends the “Caller Final” message to the called party with the following

information:

•

Message ID (4B)

•

Encrypted Master Key (16B or 128b)

•

Encrypted Master Salt (16B or 128b)


67

4


Using a Mini-Certificate The Master Key and Master Salt are encrypted with the public key from the called party mini-certificate. The Master Key and Master Salt are used by both ends for deriving session keys to encrypt subsequent RTP packets. The called party then responds with a Callee Final message (which is an empty message). The Mini-Certificate (MC) contains the following information:

•

Name (32B)

•

ID or Phone Number (16B)

•

Expiration Date (12B)

•

Public Key (512b or 64B)

•

Signature (1024b or 512B)

The MC has a 512-bit public key used for establishing secure calls. The must provision each subscriber of the secure call service with an MC and the corresponding 512-bit private key. The MC is signed with a 1024-bit private key of the service provider, which acts as the CA of the MC. The 1024-bit public key of the CA g the MC must also be provisioned for each subscriber. The CA public key is used to the MC received from the other end. If the MC is invalid, the call will not switch to secure mode. The MC and the 1024-bit CA public key are concatenated and base64 encoded into the single parameter Mini Certificate. The 512-bit private key is base64 encoded into the SRTP Private Key parameter, which should be kept secret, like a . (Mini Certificate and SRTP Private Key are configured in the Line tabs.) Because the secure call establishment relies on exchange of information embedded in message bodies of SIP INFO requests/responses, the service provider must ensure that the network infrastructure allows the SIP INFO messages to through with the message body unmodified.

Generating a Mini Certificate Cisco provides a Mini Certificate Generator for the generation of mini certificates and private keys. Partners can the Mini Certificate Generator by going to Cisco Partner Central, Voice & Conferencing page, Technical Resources section. Use the following URL: http://www.cisco.com/web/partners/sell/smb/products/ voice_and_conferencing.html#~vc_technical_resources

NOTE The partner sites require a logon.

The Mini Certificate Generator uses the following syntax: gen_mc

ca-key -name -id expire-date

Where:

•

ca-key is a text file with the base64 encoded 1024-bit CA private/public key pairs for g/ing the MC, such as the following:

•

-name is the name of the subscriber, such as “Joe Smith”. Maximum length is 32 characters

•

-id is the ID of the subscriber, which must match exactly the -id used in the INVITE when making the call, such as “14083331234”. The maximum length is 16 characters.

•

expire-date is the expiration date of the MC, such as “00:00:00 1/1/34” (34=2034). Internally the date is encoded as a fixed 12B string: 000000010134

The tool generates the Mini Certificate and SRTP Private Key parameters that can be provisioned. EXAMPLE: gen_mc ca_key “Joe Smith” 14085551234 “00:00:00 1/1/34”

SIP Trunking and Hunt Groups on the SPA8000

4

SIP Trunking and Hunt Groups on the SPA8000 The SPA8000 s SIP Trunking, which allows you to connect a traditional PBX to VoIP services. In this configuration, calls go through the ITSP rather than the PSTN, yet the call routing functionality is similar to that of traditional PSTN lines. You can configure up to four trunk groups for the purpose of inbound call routing and outbound caller identification. You can configure a trunk number on the SPA8000, such that an incoming call automatically rings the grouped lines simultaneously or in a specified order. For outbound calls, SIP Trunking ensures that all calls on a trunk line can be identified by the trunk number and a common caller ID. This feature helps you to ensure that calls are directed to available lines and that work groups such as sales teams can work together to answer calls. In addition, teams can project a common identity when placing outbound calls on a trunk. This section provides information about SIP trunking and explains how to configure your trunk groups. Refer to the following topics:

About SIP Trunking The SIP Trunking feature allows a traditional PBX to seamlessly migrate from PSTN service to VoIP service over a broadband link. The SPA8000 offers up to eight telephone lines to the PBX.

Fax

PBX System

Integrated Access Device

Internet

ITSP 194488

SPA8000

The SPA8000 offers four trunk groups, numbered T1, T2, T3, and T4. A SIP-based voice service with an ITSP can be configured on each trunk group with a distinct phone number. Each of the eight SPA8000 lines can be configured either as a standalone line, as in a classic ATA FXS port, or as a trunk line that is associated with a trunk group.

•

Inbound calling: A trunk group offers a single number for callers to call into the small business, with the capability to programmatically ring one or more trunk lines.

•

Outbound calling: When a PBX phone makes a call, the PBX selects one of the available trunk lines. The trunk line assumes the Caller ID of the trunk group.

•

SIP Path: As a standalone line, the SIP Agent (SIP UA) exchanges signaling directly with the ITSP equipment. As a trunk line, the Line UA exchanges signaling with the internal proxy server only. The Internal Proxy Server handles all SIP signalling between both ends of the call, from call establishment to termination.

•

RTP Path: Whether the line is standalone or a member of a trunk group, the Line UA exchanges RTP packets directly with the ITSP equipment.


72


4

NOTE Although the figure shows only one ITSP , each standalone line and each

Trunk Group can be configured with a different ITSP (with some limitations applied).

Setting the Trunk Group Call Capacity The ITSP may set a limit to the number of calls that can be made on a trunk group. You can configure a trunk group’s call capacity parameter to meet the requirements of the ITSP. Both incoming call and outgoing calls are counted towards this limit. The call capacity has the following impact on call handling: •

Inbound calls: When the limit is reached, the Trunk UA replies 486 to the caller.

•

Outbound calls: When the limit is reached, the Line UA plays a fast busy tone to the caller. Note that a trunk line can make an outgoing call only through its own trunk. If that trunk reaches full capacity, it will not attempt to failover to use other trunks.

You can configure this setting in the Voice tab > Trunk (T1 ... T4) page, Subscriber Information section, Call Capacity field. For more information, see “Configuring a Trunk Group,” on page 77.

Inbound Call Routing for a Trunk Group An incoming call is handled as follows: STEP 1 When an incoming call is detected by the Trunk UA, the UA first checks if there is

capacity to handle the call. If there is insufficient capacity, the UA rejects the call with a 486 response. STEP 2 If there is spare call capacity, the UA consults the List to determine which

line or lines to ring (that is, for the proxy to send SIP INVITE to), and starts “hunting.” (See “Configuring a Trunk Group,” on page 77) STEP 3 When a line is selected to ring, one or more PBX phones may be alerted, according

to the PBX features and configuration. STEP 4 The Caller ID of the external Caller is signaled by the Line UA out to the FXS port

using the configured Caller ID method (FSK, DTMF, etc.). The PBX must be able to detect Caller ID signal in order for the proper Caller ID to show.


73


4

STEP 5 If the call is picked up by the PBX, the Line UA replies 200 OK with SDP to the

internal Proxy. The Trunk UA in turn replies 200 OK to the ITSP and relay the Line SDP in the 200 OK message also. If all goes well, the Line UA and the ITSP equipment start exchanging RTP packets afterwards.

List for a Trunk Group The hunting process for incoming calls is controlled by the List. The List specifies the lines to ring, the order in which to ring them, the duration to ring one line before trying another line, and the maximum period to hunt. Below, the syntax is described and examples are provided to help you to configure the List for each trunk group. SYNTAX: line[,line[,line[…]]],hunt=hrule[,cfwd=target]

•

•

line: The line numbers (1 - 8), or a wildcard * or ? to represent all lines. •

The Trunk UA rings only trunk lines, that is, lines that are assigned to a trunk group through the Voice tab > Line page, Trunk Group field. The Trunk UA does not ring any standalone lines that are included in the List. The Trunk UA rings any trunk line that is included in the list, even if it is not assigned to the particular trunk group for this List.

•

You can instruct the SPA8000 to hunt only the phones that are on-hook, through the Voice tab > SIP page, Trunking Parameters section, Hunt Policy field. See “Setting the Hunt Policy,” on page 80.

hunt=hrule: The hunt order, ring interval, and maximum duration, in the following format: hunt=algo;interval;max •

algo: The hunt order. -

re: Restart. Hunting starts at the beginning of the list. If the first line does not answer within the specified interval (see below), the hunt proceeds through the lines in sequential order.

-

ne: Next. The Trunk UA determines the line that was chosen in the previous hunt, and hunting starts with the next line in the list. If that line does not answer within the specified interval (see below), the hunt proceeds through the lines in sequential order.

-

ra: Random order. The Trunk UA randomly chooses a line from the list. If the selected line does not answer within the specified interval (see


74


4

below), the hunt proceeds randomly through the unchosen lines until each line is tried. -

•

al: All. The Trunk UA rings all the lines at the same time.

•

interval: The number of seconds to wait for one line to answer, before choosing another line. If interval is *, the hunt is stopped at the first line that starts ringing, and rings the line until it answers, or the caller hangs up, or the line's ringer times out.

•

max: The maximum duration of the hunt, either in seconds or cycles. When this limit is reached, the call is rejected or is forwarded to the specified call forward number (see below). -

If max is greater than interval, it represents the total time in seconds to hunt.

-

If max is less than interval, it represents the maximum number of times to cycle through the hunt group. If max is 0, hunting continues indefinitely until the caller either hangs up or the call is answered. Exceptions: This value is ignored if algo = all, or interval = * (but it must be present and should be set to 1).

cfwd=target: If the call is unanswered and the maximum hunting duration has been met, the call is forwarded to the specified number. When forwarding the call, the SPA8000 sends a 302 response to the ITSP.

NOTE The call forward settings for the individual lines are ignored during hunting. Instead,

the cfwd settings in the List are used. EXAMPLES:

•

1,2,3,4,5,6,7,8,hunt=re;*;1 Lines 1 through 8 are included (1,2,3,4,5,6,7,8). The hunt starts at the beginning of the list (hunt=re). When an available line is found, the call stays with the line until the call is either answered, rejected, or cancelled by the caller (* is entered for interval).

•

?,hunt=al;30;1,cfwd=14085550100 A wildcard character (?) is used to represent “all trunk lines.” All lines ring simultaneously (hunt=al). If there is no answer after 30 seconds (30), the call is forwarded to the specified number (cfwd=14085550100).


75


4

•

?,hunt=ra;12;1,cfwd=14085550123 A wildcard character is used to represent “all trunk lines.” The Trunk UA chooses lines in random order (hunt=ra). If a selected line does not answer within 12 seconds (12), the Trunk UA chooses another line at random. If there is no answer after 1 cycle (1), the call is forwarded to forwarded to the specified number (cfwd=14085550123).

•

?,hunt=ra;*;1,cfwd=14085550155 A wildcard character is used to represent “all trunk lines.” The Trunk UA chooses lines in random order (hunt=ra). The interval is *, meaning the hunt stops when a selected line starts ringing, and will ring the line until it answers, or the caller hangs up, or the line's ringer times out. If the ringer times out, the call is automatically forwarded to the specified number (cfwd=14085550155).

Outgoing Call Routing for a Trunk Group Outbound calls on a trunk line are handled as follows: STEP 1 When a PBX phone selects an outside line, the PBX looks for an open line. If the

PBX finds an open line, it takes the line off hook and bridges the audio between the PBX phone and the line. On detecting the off hook signal, the SPA8000 Line UA plays dial tone and ready to collect digits from the PBX phone. STEP 2 As the PBX phone dials the number, the Line UA applies its dial plan to the

number. If the Line UA detects an invalid number, it rejects the all by playing reorder tone, then howling tone, then silence. If a valid number is received, it sends a SIP INVITE message to the internal Proxy. STEP 3 The Proxy routes the call to the trunk group UA for the line, and the trunk group UA

will attempt to place the call to the ITSP if there is available capacity on the trunk. If there is no call capacity left on the trunk, the internal Proxy will reject the INVITE from the Line UA, which in turn terminates the call and plays reorder tone out to the FXS port.

NOTE The SPA8000 will also apply the Trunk Dial Plan on the number before sending out

INVITE to the ITSP. This Trunk Dial Plan typically is redundant since the trunk should trust the number sent by the Line UA. By default the trunk dial plan allows any nonempty number: ([*#0-9A-D][*#0-9A-D].)

•

any state: The hunt includes all phones regardless of the state.

STEP 5 Click Submit All Changes.

Additional Notes About Trunk Groups This section includes information about other topics that may be of interest when you are configuring trunk groups:

•

Voice mail: There is no individual mail box for a trunk line. For example, if lines 1, 2, 3, and 4 belong the trunk group T1, then the four lines implicitly share the same voice mail box from the ITSP. When there is new voice mail waiting in the trunk mail box, the UAs for all four lines will be notified by the ITSP via the internal Proxy, and all four lines will show the message waiting indicator, such as by playing stutter dial tone, if enabled by the .

•

Supplementary features: Supplementary features are offered at the line level only, not at the trunk level. Via the PBX, the phone can trigger/control supplementary service and settings by signaling to the line port or configuring the line parameters. For more information, refer to the Appendix B, “ATA Voice Field Reference.”

STEP 6 Click Submit All Changes. The unit reboots. Then the unit s the file and

stores it in flash memory.

Configuring a Streaming Audio Server This section describes how to use and configure a streaming audio server (SAS). It includes the following topics:

•

“About the Streaming Audio Server,” on page 83

•

“Configuring the Streaming Audio Server,” on page 85

•

“Using the IVR with an SAS Line,” on page 86

About the Streaming Audio Server The Streaming Audio Server (SAS) feature lets you attach an audio source to an FXS port and use it as a streaming audio source device. If the unit has multiple FXS ports, either or both of the associated lines can be configured as an SAS server. Use a media signal adapter or “music coupler” to connect an Ethernet cable from a media source to the FXS port. For example, the MC-9700 Music Coupler has been tested with ATA devices and is available at the following URL: www.neogadgets.com/cart/ cart.php?target=product&product_id=17&substring=music+coupler


83

After you complete the required configuration, the FXS port is ready to stream audio. The functionality depends on the hook state of the FXS port:

•

If the FXS port is off hook, an incoming call is answered automatically and audio is streamed to the calling party.

NOTE Each SAS server can maintain up to five simultaneous calls. If the

second line on the unit is disabled, then the SAS line can maintain up to 10 simultaneous calls. Further incoming calls receive a busy signal (SIP 486 Response).

•

If the FXS port is on-hook when the incoming call arrives, a SIP 503 response code is transmitted to indicate “Service Not Available.”

•

If an incoming call is auto-answered, but later the FXS port changes to on-hook, the call is not terminated but continues to stream silence packets to the caller.

•

The SAS line can be set up to refresh each streaming audio session periodically using a SIP re-INVITE message, which detects if the connection to the caller is down. If the caller does not respond to the refresh message, the SAS line terminates the call so that the streaming resource can be used for other callers.

Additional information:

•

The SAS line does not ring for incoming calls even if the attached equipment is on-hook.

•

If no calls are in session, battery is removed from tip-and-ring of the FXS port. Some audio source devices have an LED to indicate the battery status. This can be used as a visual indication as to whether audio streaming is in progress.

•

Call Forwarding, Call Screening, Call Blocking, DND, and Caller-ID Delivery features are not available on an SAS line.


84


5

Configuring the Streaming Audio Server Use the following procedure to configure an SAS with an external music source. STEP 1 Connect an RJ-11 adapter between the music source (a CD player or iPod, for

example) and an FXS port. STEP 2 Start Internet Explorer, connect to the istration web server, and choose

access with Advanced settings. STEP 3 Configure the FXS port:

a. Click Voice tab > FXS N, where N represents the number of the FXS port where you connected the cable from the external music source. b. In the Subscriber Infomation section, enter the following settings: •

Display Name: Enter an extension number of name for the FXS 1 port, such as Receptionist Area Fax Machine.

•

ID: Enter a three- to four-digit extension number that is not is use by another extension.

c. In the Streaming Audio Server (SAS) section, choose yes from the SAS Enable drop-down list. STEP 4 Click Submit All Changes. STEP 5 Configure each phone to use this audio source as the MOH server:

a. Click the PBX Status link to view the list of phones. b. In the list, find the phone that you want to configure, and then click the hyperlink in the IP Address column. The Telephone Configuration page appears in a separate window. c. Click the Ext 1 tab. d. Scroll down to the Call Feature Settings section. e. In the MOH Server field, enter the extension number that you assigned to the FXS port for the streaming audio server. f.

Click Submit All Changes.


85


5

g. Close the window for the Telephone Configuration page. h. Repeat this step to configure each phone, as needed.

Using the IVR with an SAS Line The IVR can still be used on an SAS line, but the needs to follow the following steps: STEP 1 Power off the ATA device. STEP 2 Connect a phone to the port and make sure the phone is on-hook. STEP 3 Power on the ATA device. STEP 4 Pick up handset and press * * * * to invoke IVR in the usual way.

If the ATA device boots and finds that the SAS line is on-hook, it does not remove battery from the line so that IVR may be used. But if the ATA device boots up and finds that the SAS line is off-hook, it removes battery from the line because no audio session is in progress.

“Call Scenarios” section on page 95

Connecting to PSTN and VoIP Services Both the SPA3102 and the SPA8800 allow your analog and IP phones to participate in calls over the VoIP network and the PSTN. Both devices provide a VoIP-To-PSTN calling function, which is referred to as a PSTN gateway, as well as a PSTN-To-VoIP calling function, which is referred to as a VoIP gateway. These ATAs function somewhat differently because they are designed to meet different business needs. •

The SPA3102 is designed to work independently as a PSTN gateway and VoIP gateway, without relying on a PBX for call control. -

FXS Port: The SPA3102 has 1 FXS port that you can connect to a standard analog telephone or fax machine. Configure the FXS settings by using the SPA3102 Line page.

FXO Port: The SPA3102 has 1 FXO port that you can connect to the PSTN. Configure the FXO settings by using the SPA3102 PSTN Line page.

The SPA8800 is designed to work with your PBX as a PSTN gateway and a VoIP gateway. Call control is provided by a standard PBX, an Asteriskbased IP PBX, the SPA9000 Voice System, or an Internet-based call control system. -

FXS Port: The SPA8800 has 4 FXS ports that you can connect to standard analog telephones or fax machines. Configure the FXS settings by using the SPA8800 Phone 1-4 pages.

-

FXO Port: The SPA8800 has 4 FXO port sthat you can connect to the PSTN. Configure the FXO settings by using the SPA8800 Line 1-4 pages.

How VoIP-To-PSTN Calls Work To obtain PSTN services through the SPA3102 or the SPA8800, the VoIP caller establishes a connection with the PSTN Line by way of a standard SIP INVITE request addressed to the PSTN Line.

One-Stage Dialing (SPA3102 and SPA8800) One-stage dialing allows a call to be started over VoIP and then immediately get a dial tone on the PSTN. When you take a phone off hook and dial a number, the call is automatically routed to the VoIP or the PSTN, based on the dial plan. On the SPA3102, you can enable HTTP Digest Authentication. In this case, the SPA3102 challenges the INVITE with a 401 response if it does not have a valid Authorization header. The Authorization header should include a < ID n> parameter, where n refers to one of eight VoIP s that can be configured on the ATA device. The credentials are computed based on the corresponding using Message Digest 5 (MD5). The < ID n> parameter must match one of the VoIP s stored on the ATA device. You can configure these settings on the Voice tab > PSTN Line page. For more information, see “VoIP s and s (HTTP Authentication) section,” on page 208.


88

Configuring the PSTN (FXO) Gateway on the SPA3102 How VoIP-To-PSTN Calls Work

6

Two-Stage Dialing (SPA3102) In two-stage dialing, the SPA3102 takes the FXO port off-hook but does not automatically dial any digits after accepting the call. To invoke two-stage dialing, the VoIP caller should INVITE the PSTN Line without the -id in the Request-URI or with a -id that matches exactly the < ID n> of the PSTN Line. A different -id in the Request-URI is treated as a request for one-stage dialing if onestage dialing is enabled, or dropped by the SPA3102 (as if no -id is given) if one-stage dialing is disabled. HTTP Digest Authentication can be also used for two-stage dialing, as in onestage dialing. If using HTTP Digest Authentication or Authentication is disabled, the VoIP caller should hear the PSTN dial tone right after the call is answered (by a SIP 200 response). You also can enable PIN authentication. In this case, the VoIP caller is prompted to enter a PIN number after the SPA3102 answers the call. The PIN number must end with a # key. The inter-PIN-digit timeout is 10 seconds (not configurable). Up to eight VoIP caller PIN numbers can be configured on the SPA3102. A dial plan can be selected for each PIN number. If the caller enters a wrong PIN or the SPA3102 times out waiting for more PIN digits, the SPA3102 tears down the call immediately with a BYE request. The call scenarios may involve the following types of callers:

•

VoIP caller—Someone who calls the ATA device via VoIP to obtain PSTN service

•

VoIP —A VoIP caller that has a (-id and ) on the SPA3102

•

PSTN caller—Someone who calls the ATA device from the PSTN to obtain VoIP service

VoIP callers can be authenticated by one of the following methods:

•

No Authentication—All callers are accepted for service.

•

PIN—Caller is prompted to enter a PIN right after the call is answered.

•

HTTP digest—SIP INVITE must contain a valid authorization header.

PSTN callers can be authenticated by one of the following methods:

•

No authentication—All callers are accepted for service.

•

PIN—Caller is prompted to enter a PIN right after the call is answered.


89

Configuring the PSTN (FXO) Gateway on the SPA3102 How PSTN-To-VoIP Calls Work

NOTE When the source address of the INVITE is 127.0.0.1, authentication is automatically

disabled because this is a call by the local . This applies to both one-stage and two-stage dialing. These settings can be configured on the SPA3102 PSTN Line page. See “VoIPTo-PSTN Gateway Setup section,” on page 206.

How PSTN-To-VoIP Calls Work For PSTN-to-VoIP calls, the basic PSTN-to-VoIP call flow is as follows: 1. When a PSTN call comes in to the ATA device and is unanswered (after a configurable number of rings), then the ATA device takes the FXO port off hook. 2. The ATA device plays dial tone. 3. The PSTN caller enters the target telephone number. The collected digits are processed by the default dial plan. On the SPA3102, you can add PIN authentication to the basic flow: 1. When a PSTN call comes in to the ATA device and is unanswered (after a configurable number of rings), then the ATA device takes the FXO port off hook. 2. The SPA3102 prompts the caller to enter the PIN number followed by the # key. 3. The SPA3102 compares the PIN to the configured PSTN PIN values. •

If the PIN matches one of the configured PSTN PIN values, then the SPA3102 plays dial tone. The caller enters the telephone number and the collected digits are processed by the dial plan associated with the PIN number. (These dial plans are configured on the Voice Voice tab > PSTN Line page, Dial Plans section.)

•

If the PIN does not match one of the configured PSTN PIN values, then the ATA device plays the reorder tone and then takes the FXO port on-hook.

NOTE For information about configuring the timer values for the above scenarios, see

“FXO (PSTN) Timer Values (sec) section,” on page 209. For information about configuring caller authentication on the SPA3102, see “VoIPTo-PSTN Gateway Setup section,” on page 206.

Terminating Gateway Calls There are two call legs in a PSTN gateway call: the PSTN call leg and the VoIP call leg. A gateway call is terminated when either call leg is ended. When the call terminates, the FXO port goes on-hook so the PSTN line is available for use. The ATA device detects that the PSTN call leg is ended when one of the following conditions occurs during a call: •

The PSTN Line voltage drops to a very low value (this occurs if the line is disconnected from the PSTN service or if the PSTN switch provides a C signal).

•

A polarity reversal or disconnect tone is detected at the FXO port.

•

There is no voice activity for a configurable period of time in either direction at the FXO port.

When any of the above conditions occur, the ATA device takes the FXO port on hook and sends a BYE request to end the VoIP call leg. On the other hand, when the ATA device receives a SIP BYE from the VoIP during a call, it takes the FXO port on hook to end the PSTN call leg. In addition, the ATA device can also send a refresh signal periodically to the VoIP call leg to determine whether the call leg is still up. If a refresh operation fails, the ATA device ends both call legs. On the SPA3102, these settings can be configured on the Voice tab > PSTN Line page. For more information, see “PSTN Disconnect Detection section,” on page 211. On the SPA8800, these settings can be configured on the Voice tab > Phone page. For more information, see “FXS Port Polarity Configuration section,” on page 177.

Configuring the PSTN (FXO) Gateway on the SPA3102 VoIP Outbound Call Routing (SPA3102)

VoIP Outbound Call Routing (SPA3102) On the SPA3102, calls made from Line 1 are routed through the configured Line 1 service provider, by default. You can override this behavior by IP dialing, through which the calls can be routed to any IP address that the enters. The SPA3102 allows flexible call routing with four sets of gateway parameters and configurable dial plans. These settings are configured on the SPA3102 Voice tab > Line page. See “Gateway s section (SPA3102),” on page 174.

NOTE The PBX handles outbound call routing for the SPA8800.

You can specify Gateways 1 to 4 in a dial plan by using the identifiers gw1, gw2, gw3, or gw4. Also, gw0 represents the internal PSTN gateway via the FXO port. You can specify in the dial plan to use gwx (x = 0,1,2,3,4) when making certain calls. In general, you can specify any gateway address in the dial plan. In addition, three parameters are added that can be used with call routing:

•

usr: -id used for authentication with the given gateway

•

pwd: used for authentication with the given gateway

•

nat: Enable or disable NAT mapping when calling the gateway

The following table lists some examples. Example

Description

<9,:>xx.<:@gw1

Dial 9 to start outside dial tone, followed by one or more digits, and route the call to Gateway 1.

[93]11<:@gw0>

Route 911 and 311 calls to the local PSTN gateway

<8,:1408>xxxxxxx<:@pstn. cisco.com:5061;usr=joe; pwd=joe_pwd;nat>

Dial 8 to start outside dial tone, prepend 1408 followed by seven digits, and route the call to pstn.cisco.com:5061, with -id = joe, and pwd = bell_pwd, and enable NAT mapping

<8,:1408>xxxxxxx<:@gw2:5061; usr=”Alex Bell”;pwd= ”anything”;nat=no>

Dial 8 to start outside dial tone, prepend 1408 followed by seven digits, and route the call to Gateway 2, but use the given port, -id, and , and no pstn.cisco.com:5061, and with -id = “Alex Bell” and pwd = bell_pwd, and disable NAT mapping

Configuring the PSTN (FXO) Gateway on the SPA3102 Configuring VoIP Failover to PSTN

6

You can set up multiple PSTN gateways at different locations and configure Line 1 to use a different gateway when dialing specific numbers.

Configuring VoIP Failover to PSTN When power is disconnected from the ATA, the FXS port is connected to the FXO port. In this case, the telephone attached to the FXS port is electrically connected to the PSTN service via the FXO port. When power is applied to the ATA device, the FXS port is disconnected from the FXO port. However, if the PSTN line is in use when the power is applied to the ATA device, the relay is not flipped until the PSTN line is released. This feature ensures that the ATA device does not interrupt any call in progress on the PSTN line. When Line 1 VoIP service is down (because of registration failure or loss of network link), the ATA device can be configured to automatically route all outbound calls to the internal gateway using the parameter listed below. For SPA3102, you can configure this setting on the Voice tab > Line page. For SPA8800, you can configure this setting on the Voice tab > Phone page. For more information, see “VoIP Fallback to PSTN section (SPA3102 and SPA8800),” on page 175.

Sharing One VoIP Between the FXS and PSTN Lines (SPA3102) On the SPA3102, both the FXS (Line 1) and FXO (PSTN Line) can receive incoming calls for a single VoIP if they are different ports. Consider the following points: •

If the service provider allows multiple registration s and simultaneous ringing, both lines can periodically with the service provider. In this case, both lines receive inbound calls to this VoIP . The PSTN Line should be configured with a sufficiently long answer delay before the call is automatically answered to allow for the function of the PSTN gateway.

•

If the service provider does not allow more than one , the PSTN Line should not . In this case, only Line 1 rings on the inbound call to this VoIP because it is the only line ed with the service provider.

Line 1 can have the call forwarded to the PSTN Line after a few seconds using the Call-Forward-On-No-Answer feature with gw0 as the forward destination. Similarly, Line 1 can apply Call-Forward-All, Call-Forward-OnBusy, and Call-Forward-Selective feature, and direct the caller to the PSTNGateway.

Only PIN authentication is allowed when a VoIP caller is forwarded to the PSTN-gateway from Line 1. If HTTP Authentication is used, the caller is not authenticated.

•

When using the Forward-To-GW0 feature, you can forward the caller to a specific PSTN number, using the syntax @gw0 in the forward destination. When using this with Call-Forward-Selective, you can develop some interesting applications. For example, you can forward all callers with 408 area code to 14081234567, or all callers with 800 area code to 18005558355 (This is the number for Tell Me). When this syntax is used, authentication is not used and the target PSTN number is automatically dialed by the ATA device after the caller is forwarded to gw0.

Other Options This section describes other options provided by the SPA3102 and the SPA8800:

•

“PSTN Call to Ring Line 1 (SPA3102)” section on page 94

•

“Symmetric RTP (SPA3102 and SPA8800)” section on page 94

•

“Call Progress Tones (SPA3102 and SPA8800)” section on page 95

PSTN Call to Ring Line 1 (SPA3102) On the SPA3102, this feature allows a PSTN caller to ring Line 1. When the PSTN line rings, the PSTN Line makes a local VoIP call to Line 1. If Line 1 is busy, it stops. After a given number of rings, the VoIP gateway picks up the call.

Symmetric RTP (SPA3102 and SPA8800) The Symmetric RTP parameter is used to send audio RTP to the source IP and port of the inbound RTP packets. This facilitates NAT traversal. See “SIP Parameters section,” on page 122.

Configuring the PSTN (FXO) Gateway on the SPA3102 Call Scenarios

6

Call Progress Tones (SPA3102 and SPA8800) The SPA3102 and the SPA8800 have configurable call progress tones. Call progress tones are generated locally on the ATA, so an end is advised of status (such as ringback). Parameters for each type of tone (for instance a dial tone played back to an end ) may include the following specifications:

•

Number of frequency components

•

Frequency and amplitude of each component

•

Cadence information

When one VoIP is shared between the FXS and PSTN Lines, the following parameters are recommended to be set. For more information, see the Regional page in the “ATA Voice Field Reference,” on page 110.

Call Progress Tone

Description

VoIP PIN Tone

This tone is played to prompt a VoIP caller to enter a PIN number.

PSTN PIN Tone

This tone is played to prompt a PSTN caller to enter a PIN number.

Outside Dial Tone

During two-stage PSTN-gateway dialing and with a dial plan assigned, the ATA device collects digits from the VoIP caller and processes the number using the dial plan. The ATA device plays the Outside Dial Tone to prompt the VoIP caller to enter the PSTN number. This tone should be specified to sound different from the PSTN dial tone.

Call Scenarios This section describes some typical scenarios where the ATA device can be applied. Some are introduced in the first few sections and reused in later sections. This section includes the following topics:

•

“PSTN to VoIP Call with and Without Ring-Thru” section on page 96

•

“VoIP to PSTN Call With and Without Authentication” section on page 96

•

“Call Forwarding to PSTN Gateway (SPA3102 and SPA8800)” section on page 98

PSTN to VoIP Call with and Without Ring-Thru The PSTN caller calls the PSTN line connected to the FXO port. Ring-Thru is disabled. After the call rings for a delay equal to the value in PSTN Answer Delay, the VoIP gateway answers the call and prompts the PSTN caller to enter a PIN number (assuming PIN authentication is enabled). After a valid PIN is entered, the caller is prompted to dial the VoIP number. A dial plan is selected according to the PIN number entered by the caller. If authentication is disabled, the default PSTN dial plan is used. Note than the dial plan choice cannot be 0 for a PSTN caller.

NOTE A PSTN Access List in of Caller ID (ANI) patterns can be configured into the

ATA device to automatically grant access to the PSTN caller without entering the PIN. In this case, the default PSTN dial plan is also used. The same scenario can be implemented using Ring-Thru. When the PSTN line rings, Line 1 rings also. This feature is called Ring-Thru. If Line1 is picked up before the VoIP gateway auto-answers, it is connected to the PSTN call. Line 1 hears a call waiting tone if it is already connected to another call.

VoIP to PSTN Call With and Without Authentication This section describes three scenarios with and without authentication and includes the following topics:

•

“Using PIN Authentication (SPA3102)” section on page 96

•

“Using HTTP Digest Authentication (SPA3102)” section on page 97

•

“Without Authentication (SPA3102 and SPA8800)” section on page 98

Using PIN Authentication (SPA3102) This scenario assumes that the PSTN Line has a different VoIP than the Line 1 . The VoIP caller calls the FXO number, which auto-answers after VoIP Answer Delay. The ATA device then prompts the VoIP caller for a PIN. When a valid PIN is entered, the ATA plays the Outside Dial Tone and prompts the caller to dial the PSTN number.


96


6

The number dialed is processed by the dial plan corresponding to the VoIP caller. If the dial plan choice is 0, no dial plan is needed and the hears the PSTN dial tone right after the PIN is entered. If the dial plan choice is not 0, the final number returned from the dial plan after the complete number is dialed by the caller is dialed to the PSTN. The caller does not hear the PSTN dial tone (except for a little leakage before the first digit of the final number is auto-dialed by the ATA device). If the PSTN Line is busy (off-hook, ringing, or PSTN line not connected) when the VoIP caller calls, the ATA device replies with 503. If the PIN number is invalid or entered after the VoIP call leg is connected, the ATA device plays the reorder tone to the VoIP caller and eventually ends the call when the reorder tone times out.

NOTE If VoIP Caller ID Pattern is specified and the VoIP caller ID does not match any of the

given patterns, the ATA device rejects the call with a 403. This rule applies regardless of the authentication method, even when the source IP address of the INVITE request is in the VoIP Access List .

Using HTTP Digest Authentication (SPA3102) The same scenario can be implemented with HTTP digest authentication when the calling device s the configuration of a auth-ID and to access the ATA device PSTN gateway. When the VoIP caller calls the PSTN Line, the ATA device challenges the INVITE request with a 401 response. The calling device should then provide the correct credentials in a subsequent retry of the INVITE, computed with the auth-ID and using MD5. If the credentials are correct, the target number specified in the -id field of the INVITE Request-URI is processed by the dial plan corresponding to the VoIP (assuming the dial plan choice is not 0). The final number is then auto-dialed by the ATA device. If the credentials are incorrect, the ATA device challenges the INVITE again. If the auth-ID does not exist in the ATA device configuration, the ATA device replies 403 to the INVITE. If the target number is invalid according to the corresponding dial plan, the ATA device also replies 403 to the INVITE. Again, if the PSTN Line is busy at the time of the call, the ATA device replies 503.


97


6

NOTE HTTP Digest Authentication is one way to perform one-stage dialing of a VoIP-To-

PSTN call. The other way is with no authentication require. However, if the target number is not specified in the Request-URI or the number matches the -id of the PSTN Line, the call reverts to two-stage dialing.

Without Authentication (SPA3102 and SPA8800) This scenario can also be implemented without authentication, using one-stage or two-stage dialing, as in the HTTP Authentication case. The default VoIP caller dial plan is used in this scenario. Authentication is performed when the method is none or when the source IP address of the inbound INVITE matches one of the VoIP Access List patterns.

Call Forwarding to PSTN Gateway (SPA3102 and SPA8800) This section describes a number of scenarios that forward calls to the PSTN gateway. It includes the following topics:

•

“Forward-On-No-Answer to the PSTN Gateway” section on page 98

•

“Forward-All to the PSTN gateway” section on page 99

•

“Forward to a Particular PSTN Number” section on page 99

•

“Forward-On-Busy to PSTN Gateway or Number” section on page 99

On the SPA3102, you can configure Call Forward settings on the page. On SPA8800, the same parameters are set on the Phone page. For field descriptions, see Call Forward Settings section.

Forward-On-No-Answer to the PSTN Gateway In this scenario, Line 1 is configured to Cfwd No Ans Dest to the PSTN Gateway. The scenario is implemented by setting 1 to forward to gw0 on no answer, with Cfwd No Ans Delay set to six seconds. The caller calls Line 1 and if Line 1 is not picked up after six seconds, the PSTN Line picks up the call and the call reverts to a PSTN-Gateway call, as described above. In this case, HTTP authentication is not allowed because Line 1 does not authenticate inbound INVITE requests. If you need to authenticate the VoIP caller in this case, you must select the PIN authentication method, or else the caller is not authenticated.


98


6

NOTE If the PSTN Line is busy at the moment of the forward, it does not answer the VoIP

call. The call forward rule is ignored and Line 1 continues to ring.

Forward-All to the PSTN gateway In this scenario, Line 1 is configured with Cfwd All Dest parameter to the PSTN gateway.This scenario is the same the previous case, except the FXO picks up the Line 1 call immediately. If the PSTN Line is busy at the moment of the call, the PSTN Line does not pick up the call, the call forward rule is ignored, and Line 1 continues to ring.

Forward to a Particular PSTN Number In this scenario, the forward destination is set to @gw0>. This is the same as in the previous examples, except that the ATA device automatically dials the given target number on the PSTN line right after it answers the VoIP call leg. This is a special case of one-stage dialing where the target number is specified in the configuration. The caller is not authenticated in this case regardless of the authentication method. However, the caller is still limited by the VoIP Caller ID Pattern parameter

Forward-On-Busy to PSTN Gateway or Number This scenario is similar to the previous cases of call forwarding to gw0, but this applies when Line 1 is active.

141

B


Call Back Delay

Delay after receiving the first SIP 18x response before declaring the remote end is ringing. If a busy response is received during this time, the ATA device still considers the call as failed and keeps on retrying. The default is 0.5.

VMWI Refresh Intvl

Interval between VMWI refresh to the E. The default is 0.5.

Interdigit Long Timer

Long timeout between entering digits when dialing. The interdigit timer values are used as defaults when dialing. The Interdigit_Long_Timer is used after any one digit, if all valid matching sequences in the dial plan are incomplete as dialed. Range: 0–64 seconds. The default is 10.

Interdigit Short Timer

Short timeout between entering digits when dialing. The Interdigit_Short_Timer is used after any one digit, if at least one matching sequence is complete as dialed, but more dialed digits would match other as yet incomplete sequences. Range: 0–64 seconds. The default is 3.

C Delay

Delay in seconds after caller hangs up when the ATA device starts removing the tip-and-ring voltage to the attached equipment of the called party. Range: 0–255 seconds. ATA device has had polarity reversal feature since release 1.0 which can be applied to both the caller and the callee end. This feature is generally used for answer supervision on the caller side to signal to the attached equipment when the call has been connected (remote end has answered) or disconnected (remote end has hung up). This feature should be disabled for the called party (in other words, by using the same polarity for connected and idle state) and the C feature should be used instead. Without C enabled, reorder tone will is played after a configurable delay. If C is enabled, dial tone will be played when tip-to-ring voltage is restored Resolution is 1 second. The default is 2.


142

B


C Duration

Duration in seconds for which the tip-to-ring voltage is removed after the caller hangs up. After that, tip-to-ring voltage is restored and dial tone applies if the attached equipment is still off-hook. C is disabled if this value is set to 0. Range: 0 to 1.000 second. Resolution is 0.001 second. The default is 0 (C disabled).

Referral Services Codes

B These codes tell the ATA device what to do when the places the current call on hold and is listening to the second dial tone. One or more *code can be configured into this parameter, such as *98, or *97|*98|*123, etc. Max total length is 79 chars. This parameter applies when the places the current call on hold (by Hook Flash) and is listening to second dial tone. Each *code (and the following valid target number according to current dial plan) entered on the second dial-tone triggers the ATA device to perform a blind transfer to a target number that is prepended by the service *code. For example, after the dials *98, the ATA device plays a special dial tone called the Prompt Tone while waiting for the the enter a target number (which is checked according to dial plan as in normal dialing). When a complete number is entered, the ATA device sends a blind REFER to the holding party with the Refer-To target equals to *98 target_number. This feature allows the ATA device to hand off a call to an application server to perform further processing, such as call park. The *codes should not conflict with any of the other vertical service codes internally processed by the ATA device. You can empty the corresponding *code that you do not want to ATA device to process.

Feature Dial Services Codes

These codes tell the ATA device what to do when the is listening to the first or second dial tone. One or more *code can be configured into this parameter, such as *72, or *72|*74|*67|*82, etc. Max total length is 79 chars. This parameter applies when the has a dial tone (first or second dial tone). Enter *code (and the following target number according to current dial plan) entered at the dial tone triggers the ATA device to call the target number prepended by the *code. For example, after dials *72, the ATA device plays a special tone called a Prompt tone while awaiting the to enter a valid target number. When a complete number is entered, the ATA device sends a INVITE to *72 target_number as in a normal call. This feature allows the proxy to process features like call forward (*72) or BLock Caller ID (*67). The *codes should not conflict with any of the other vertical service codes internally processed by the ATA device. You can empty the corresponding *code that you do not want to ATA device to process. You can add a parameter to each *code in Features Dial Services Codes to indicate what tone to play after the *code is entered, such as *72‘c‘|*67‘p‘. Below are a list of allowed tone parameters (note the use of back quotes surrounding the parameter w/o spaces) ‘c‘ = ‘d‘ = ‘m‘ = <MWI Dial Tone> ‘o‘ = ‘p‘ = ‘s‘ = <Second Dial Tone> ‘x‘ = No tones are place, x is any digit not used above If no tone parameter is specified, the ATA device plays Prompt tone by default. If the *code is not to be followed by a phone number, such as *73 to cancel call forwarding, do not include it in this parameter. In that case, simple add that *code in the dial plan and the ATA device send INVITE *73@..... as usual when dials *73.

Daylight Saving Time Rule

Enter the rule for calculating daylight saving time; it should include the start, end, and save values. This rule is comprised of three fields. Each field is separated by ; (a semicolon) as shown below. Optional values inside [ ] (the brackets) are assumed to be 0 if they are not specified. Midnight is represented by 0:0:0 of the given date. SYNTAX: Start = <start-time>; end=<end-time>; save = <save-time>. The <start-time> and <end-time> values specify the start and end dates and times of daylight saving time. Each value is in this format: <month> / / <weekday>[/ HH:[mm[:ss]]] The <save-time> value is the number of hours, minutes, and/or seconds to add to the current time during daylight saving time. The <save-time> value can be preceded by a negative (-) sign if subtraction is desired instead of addition. The <save-time> value is in this format: [/[+|-]HH:[mm[:ss]]] The <month> value equals any value in the range 1-12 (January-December). The value equals [+|-] any value in the range 1-31. If is 1, it means the <weekday> on or before the end of the month (in other words the last occurrence of < weekday> in that month). The <weekday> value equals any value in the range 1-7 (Monday-Sunday). It can also equal 0. If the <weekday> value is 0, this means that the date to start or end daylight saving is exactly the date given. In that case, the value must not be negative. If the <weekday> value is not 0 and the value is positive, then daylight saving starts or ends on the <weekday> value on or after the date given. If the <weekday> value is not 0 and the value is negative, then daylight saving starts or ends on the <weekday> value on or before the date given. The abbreviation HH stands for hours (0-23). The abbreviation mm stands for minutes (0-59). The abbreviation ss stands for seconds (0-59). The default Daylight Saving Time Rule is start=4/1/ 7;end=10/-1/7;save=1.

SAS Enable

To enable the use of the line as a streaming audio source, select yes. Otherwise, select no. If enabled, the line cannot be used for outgoing calls. Instead, it auto-answers incoming calls and streams audio RTP packets to the caller. The default is no.

SAS DLG Refresh Intvl

If this value is not zero, it is the interval at which the streaming audio server sends out session refresh (SIP reINVITE) messages to determine whether the connection to the caller is still active. If the caller does not respond to the refresh message, the ATA device ends this call with a SIP BYE message. The range is 0 to 255 seconds (0 means that the session refresh is disabled). The default is 30.


157

B


SAS Inbound RTP Sink

This setting works around devices that do not play inbound RTP if the streaming audio server line declares itself as a send-only device and tells the client not to stream out audio. Enter a Fully Qualified Domain Name (FQDN) or IP address of an RTP sink; this value is used by the streaming audio server line in the SDP of its 200 response to an inbound INVITE message from a client. The purpose of this parameter is to work around devices that do not play inbound RTP if the SAS line declares itself as a send-only device and tells the client not to stream out audio. This parameter is a FQDN or IP address of a RTP sink to be used by the SPA SAS line in the SDP of its 200 response to inbound INVITE from a client. It will appear in the c = line and the port number and, if specified, in the m = line of the SDP. If this value is not specified or equal to 0, then c = 0.0.0.0 and a=sendonly will be used in the SDP to tell the SAS client to not to send any RTP to this SAS line. If a non-zero value is specified, then a=sendrecv and the SAS client will stream audio to the given address. Special case: If the value is $IP, then the SAS line’s own IP address is used in the c = line and a=sendrecv. In that case the SAS client will stream RTP packets to the SAS line. The default value is empty.

SIP Settings section

Field

Description

SIP Transport

The T choice provides “guaranteed delivery,” which assures that lost packets are retransmitted. T also guarantees that the SIP packages are received in the same order that they were sent. As a result, T overcomes the main disadvantages of UDP. In addition, for security reasons, most corporate firewalls block UDP ports. With T, new ports do not need to be opened or packets dropped, because T is already in use for basic activities such as Internet browsing or e-commerce. Options are: UDP, T, TLS. The default is UDP. Applies to SPA2102, SPA3102, and SPA8800.

SIP Port

Port number of the SIP message listening and transmission port. The default is 5060.

SIP Outbound Proxy Server where all outbound requests are sent as the first hop.

Use Outbound Proxy

Enablse the use of an Outbound Proxy. If set to no, the Outbound Proxy and Use OB Proxy in Dialog parameters are ignored. The default is no.

Use OB Proxy In Dialog

Whether to force SIP requests to be sent to the outbound proxy within a dialog. Ignored if the parameter Use Outbound Proxy is no, or the Outbound Proxy parameter is empty. The default is yes.

Enable periodic registration with the Proxy parameter. This parameter is ignored if Proxy is not specified. The default is yes.

Make Call Without Reg

Allow making outbound calls without successful (dynamic) registration by the unit. If No, dial tone will not play unless registration is successful. The default is no.

Expires

Allow answering inbound calls without successful (dynamic) registration by the unit. If proxy responded to with a smaller Expires value, the PAP2T will renew registration based on this smaller value instead of the configured value. If registration failed with an Expires too brief error response, the PAP2T will retry with the value given in the Min-Expires header in the error response. The default is 3600.


164

B


Ans Call Without Reg

Expires value in sec in a request. The PAP2T will periodically renew registration shortly before the current registration expired. This parameter is ignored if the parameter is no. Range: 0 – (231 – 1) sec

Use DNS SRV

Whether to use DNS SRV lookup for Proxy and Outbound Proxy. The default is no.

DNS SRV Auto Prefix

If enabled, the PAP2T will automatically prepend the Proxy or Outbound Proxy name with _sip._udp when performing a DNS SRV lookup on that name. The default is no.

Proxy Fallback Intvl This parameter sets the delay (sec) after which the PAP2T will retry from the highest priority proxy (or outbound proxy) servers after it has failed over to a lower priority server. This parameter is useful only if the primary and backup proxy server list is provided to the PAP2T via DNS SRV record lookup on the server name. (Using multiple DNS A record per server name does not allow the notion of priority and so all hosts will be considered at the same priority and the PAP2T will not attempt to fall back after a fail over). The default is 3600 Proxy Redundancy Method

PAP2T will make an internal list of proxies returned in DNS SRV records. In normal mode, this list will contain proxies ranked by weight and priority. if Based on SRV port is configured the PAP2T does normal first, and also inspect the port number based on 1st proxy’s port on the list. The default is Normal.

Audio Configuration section A codec resource is considered as allocated if it has been included in the SDP codec list of an active call, even though it eventually may not be the one chosen for the connection. So, if the G.729a codec is enabled and included in the codec list, that resource is tied up until the end of the call whether or not the call actually uses G.729a. If the G.729a resource is already allocated and since only one G.729a resource is allowed per device, no other low-bit-rate codec may be allocated for subsequent calls; the only choices are G711a and G711u. On the other hand, two G.723.1/G.726 resources are available per device. Therefore it is important to disable the use of G.729a in order to guarantee the of two simultaneous G.723/G.726 codec.

Preferred Codec

Preferred codec for all calls. (The actual codec used in a call still depends on the outcome of the codec negotiation protocol.) Select one of the following: G711u, G711a, G726-16, G726-24, G726-32, G726-40, G729a, or G723. The default is G711u.

There is no maximum limit. A larger value will reduce the chance of talk-off (beeping) during conversation, at the expense of reduced performance of DTMF detection, which is needed for interactive voice response systems (IVR). Default: 90 ms

FAX Process NSE

To use the fax process NSE feature, select yes. Otherwise, select no. The default is yes.

Hook Flash Tx Method

Select the method for signaling hook flash events: None, AVT, or INFO. None does not signal hook flash events. AVT uses RFC2833 AVT (event = 16).

SIP Transport

The T choice provides “guaranteed delivery”, which assures that lost packets are retransmitted. T also guarantees that the SIP packages are received in the same order that they were sent. As a result, T overcomes the main disadvantages of UDP. In addition, for security reasons, most corporate firewalls block UDP ports. With T, new ports do not need to be opened or packets dropped, because T is already in use for basic activities such as Internet browsing or e-commerce. Options are: UDP, T, TLS. The default is UDP.

Call Capacity

Maximum number of calls allowed on this trunk group. Choices: 1-15 or unlimited (16 calls). Default is unlimited. Both incoming call and outgoing call are counted towards this limit. The call capacity has the following impact on call handling:


•

Inbound calls: When the limit is reached, the Trunk SUA replies 486 to the caller.

•

Outbound calls: When the limit is reached, the Line SUA plays a fast busy tone to the caller. Note that a trunk line can make an outgoing call only through its own trunk. If that trunk reaches full capacity, it will not attempt to failover to use other trunks

189

B


List

This parameter determines which trunk lines to ring on an incoming call. When an incoming call is detected by the Trunk SUA (SIP Agent), the SUA first checks if there is capacity to handle the call. If not, the SUA rejects the call with a 486 response. If there is spare capacity, the SUA consults the List to determine which lines to ring (that is, for the proxy to send SIP INVITE to), and starts "hunting." The List specifies the lines, the hunt method, and other options. EXAMPLES: •

1,2,3,4,5,6,7,8,hunt=re;*;1 Lines 1 through 8 are participating (1,2,3,4,5,6,7,8). The Trunk SUA will hunt to each specified line in the specified order (hunt=re). The call stays with a selected line until the call is either answered, rejected, or cancelled by the caller (*). The Trunk SUA replies 486 right away if no line is available to ring at the moment (1).

•

?,hunt=al;30;0,cfwd=14089993326 A wildcard character is used to represent “all trunk lines.” All lines ring simultaneously (hunt=al). If there is no answer after 30 seconds (30), the call is forwarded to the specified number (cfwd=14089993326) .

•

?,hunt=ra;12;1,cfwd=14089993326 A wildcard character is used to represent “all trunk lines.” The Trunk SUA hunts in random order (hunt=ra). If there is no answer within 12 seconds (12), the Trunk SUA chooses another line at random. If there is no answer after 1 round (1), the call is forwarded to forwarded to the specified number (cfwd=14089993326).

List (continued)

NOTES: •

The Trunk SUA rings only trunk lines (lines that are assigned to a trunk group through the Voice tab > Line page, Trunk Group field). • •

•


The Trunk SUA will not ring any standalone lines that are included in the List. The Trunk SUA will ring any trunk line that is included in the list, even if it is not assigned to this particular trunk.

You can instruct the SPA8000 to hunt only the phones that are on-hook, through the Voice tab > SIP page, Trunking Parameters section, Hunt Policy field. See “Trunking Parameters section (SPA8000),” on page 133.

Description

Dial Plan

Dial plan script for this trunk. NOTE: The trunk SUA will also apply the Trunk Dial Plan on the number before sending out INVITE to the ITSP. This Trunk Dial Plan typically is redundant since the trunk should trust the number sent by the Line SUA. By default the trunk dial plan allows any non-empty number: ([*#0-9AD][*#0-9A-D].)

Audio Configuration section A codec resource is considered as allocated if it has been included in the SDP codec list of an active call, even though it eventually may not be the one chosen for the connection. So, if the G.729a codec is enabled and included in the codec list, that resource is tied up until the end of the call whether or not the call actually uses G.729a. If the G729a resource is already allocated and since only one G.729a resource is allowed per device, no other low-bit-rate codec may be allocated for subsequent calls; the only choices are G711a and G711u. On the other hand, two G.723.1/G.726 resources are available per device. Therefore it is important to disable the use of G.729a in order to guarantee the of two simultaneous G.723/G.726 codec.

Preferred Codec

Preferred codec for all calls. (The actual codec used in a call still depends on the outcome of the codec negotiation protocol.) Select one of the following: G711u, G711a, G726-16, G726-24, G726-32, G726-40, G729a, or G723. The default is G711u.

DTMF Tx Method

Select the method to transmit DTMF signals to the far end: InBand, AVT, INFO, Auto, InBand+INFO, or AVT+INFO. InBand sends DTMF using the audio path. AVT sends DTMF as AVT events. INFO uses the SIP INFO method. Auto uses InBand or AVT based on the outcome of codec negotiation. The default is Auto.

FAX Process NSE

To use the fax process NSE feature, select yes. Otherwise, select no. The default is yes.

Hook Flash Tx Method

Select the method for signaling hook flash events: None, AVT, or INFO. None does not signal hook flash events. AVT uses RFC2833 AVT (event = 16). INFO uses SIP INFO with the single line signal=hf in the message body. The MIME type for this message body is taken from the Hook Flash MIME Type setting. The default is None.

Disconnect Tone

This value is the tone script which describes to the SPA the tone to detect as a disconnect tone. The syntax follows a standard Tone Script with some restrictions. Default value is standard US reorder (fast busy) tone, for 4 seconds. Restrictions: •

2 frequency components must be given. If single frequency is desired, the same frequency is used for both

•

The tone level value is not used. –30 (dBm) should be used for now.

•

Only 1 segment set is allowed

•

Total duration of the segment set is interpreted as the minimum duration of the tone to trigger detection

•

6 segments of on/off time (seconds) can be specified. A 10% margin is used to validated cadence characteristics of the tone.

The Disconnect Tone Script values for various countries follow: US—480@-30,620@-30;4(.25/.25/1+2) UK—400@-30,400@-30; 2(3/0/1+2) —440@-30,440@-30; 2(0.5/0.5/1+2) —440@-30,440@-30; 2(0.5/0.5/1+2) Netherlands—425@-30,425@-30; 2(0.5/0.5/1+2) Sweden—425@-10; 10(0.25/0.25/1) Norway—425@-10; 10(0.5/0.5/1) Italy—425@-30,425@-30; 2(0.2/0.2/1+2) Spain—425@-10; 10(0.2/0.2/1,0.2/0.2/1,0.2/0.6/1) Portugal—425@-10; 10(0.5/0.5/1) Poland—425@-10; 10(0.5/0.5/1) Denmark—425@-10; 10(0.25/0.25/1) New Zealand—400@-15; 10(0.25/0.25/1) Australia—425@-13; 10(0.375/0.375/1)

tsd_products__series_home.html

Q. I want to use a different computer to access the istration web server. The address I entered did not work. A. Use the Interactive Voice Response Menu to find out the Internet IP address. Follow these steps: 1. Use a telephone connected to the Phone 1 port of the ATA device. 2. Press **** (in other words, press the star key four times). 3. After the greeting plays, press 110#. 4. Write down the IP address as it is announced. 5. Press 7932#. 6. Press 1 to enable WAN access to the istration web server. 7. Open the web browser on a networked computer. 8. Start Internet Explorer and enter the IP address of the ATA device.

Troubleshooting

Q. I’m trying to access the ATA istration web server, but I do not see the screen. Instead, I see a screen saying, “404 Forbidden.” A. If you are using Windows Explorer, perform the following steps until you see the istration web server screen (Mozilla requires similar steps). 1. Click File. Make sure Work Offline is NOT checked. 2. Press CTRL + F5. This is a hard refresh, which forces Windows Explorer to load new webpages, not cached ones. 3. Click Tools. Click Internet Options. Click the Security tab. Click the Default level button. Make sure the security level is Medium or lower. Then click the OK button. Q. How do I save my current configuration? A. Currently, the only way is to do HTTPGET from an HTTP client, from which you get the entire HTML page. Alternatively, from your browser you can select File > Save as > HTML from any of the istration web server pages. Do this in , Advanced mode. This saves all the tabs into one HTML file. This HTML file is helpful to provide to our team when you have a problem or technical question. Q. How do I debug my ATA device? Is there a syslog? A. The ATA devices send out debug information via syslog to a syslog server. The ports can be configured (by default the port is 514). 1. Make sure you do not have firewall running on your PC that could block port 514. 2. On the istration web server System tab, set Debug Server as the IP address and port number of your syslog server. Note that this address has to be reachable from the ATA device. 3. Also, set Debug level to 3. You do not need to change the value of the syslog server parameter. 4. To capture SIP signaling messages, under the Line tab, set SIP Debug Option to Full. The file output is syslog.<portnum>.log (for the default port setting, syslog.514.log).

Troubleshooting

Q. How do I access the ATA device if I forget my ? A. By default, the and s have no . If the ITSP set the for either and you do not know what it is, you need to the ITSP. If the for the was configured after you received the ATA device, you can reset the device to the factory default, which preserves any provisioning completed by the ITSP. If the needs to be reset, you have to perform a full factory reset, which also erases any provisioning. To reset the ATA device to the factory defaults, perform the following steps: 1. Connect an analog phone to the ATA device and access the IVR by pressing the asterisk key four times: **** Press the appropriate code to reset the unit: •

Press 877778# to reset the unit to the defaults as it shipped from the ITSP. This will reset the to the default of blank.

•

Press 73738# to perform a full reset of unit to the factory default settings. The will be reset to the default of blank.

2. Press 1 to confirm the operation. Press * to cancel the operation. 3. to the unit using the or without a and reconfigure the unit as necessary. Q. My ATA device is behind a NAT device or firewall and I’m unable to make a call or I’m only receiving a one-way connection. What should I do? A. Complete the following steps. 1. Configure your router to port forward “T port 80" to the IP address currently being used by your ATA device. If you do this often, we suggest that you use static IP address for the ATA device, instead of DH. (For help with port forwarding, consult your router documentation) 2. On the Line tab of the istration web server, change the value of Nat Mapping Enable to yes. On the SIP tab; change Substitute VIA Addr to yes, and the EXT IP parameter to the IP address of your router. 3. Make sure you are not blocking the UDP PORT 5060,5061 and port for UDP packets in the range of 16384-16482. Also, disable “SPI” if this feature is provided by your firewall. Identify the SIP server to which the ATA device is ing, if it s NAT, using the Outbound Proxy parameter.


226

C

Troubleshooting

4. Add a STUN server to allow traversal of UDP packets through the NAT device. On the SIP tab of the istration web server, set STUN Enable to yes, and enter the IP address of the STUN server in STUN Server. STUN (Simple Traversal of UDP through NATs) is a protocol defined by RFC 3489, that allows a client behind a NAT device to find out its public address, the type of NAT it is behind, and the port associated on the Internet connection with a particular local port. This information is used to set up UDP communication between two hosts that are both behind NAT routers. Open source STUN software can be obtained at the following website: http://www.voip-info.org/wiki-Open+Source+VOIP+Software

NOTE STUN does not work with a symmetric NAT router. Enable debug through

syslog (see FAQ#10), and set STUN Test Enable to yes. The messages indicate whether you have symmetric NAT or not.
