•Configuring Language Display for Cisco IP Phone 7940 and Cisco 7960 IP Phone (required)

•Integrating DTMF with Legacy Voice-Mail Devices (required) (required)

Configuring Language Display for Cisco IP Phone 7940 and Cisco 7960 IP Phone

Language confutation involves selecting a desired phone display language for the Cisco IP Phone 7940 and Cisco IP Phone 7960 that provides the language's character set and spelling.

Note This configuration option is available to Cisco SRS Telephony running under Cisco CallManager V3.2. Systems running software prior to Cisco CallManager V3.2 can use only the default country, United States (US).

SUMMARY STEPS

1. call-manager-fallback

2. user-locale country-code

DETAILED STEPS

Command

Purpose

Step 1

call-manager-fallback

Example:

Router(config)# call-manger-fallback

Enables SRS Telephony support.

Step 1

user-locale country-code

Example:

Router(config-cm-fallback)# user-locale ES

Selects a language for display on the Cisco IP Phone7940 and Cisco IP Phone 7960.

–United States—US (default)

•If you have software prior to Cisco CallManager V3.2, the only country-code option is US (United States).

Integrating DTMF with Legacy Voice-Mail Devices (required)

For dual tone multifrequency (DTMF) integrations, information on how to route incoming or forwarded calls is sent by the telephone system in the form of DTMF digits. The DTMF digits are in the form of a pattern and depend on the voice-mail system connected to the Cisco SRS Telephony router. These patterns are required for the DTMF integration with most voice-mail systems. The DTMF integration configuration on the Cisco SRS Telephony router works with any analog voice-mail system. Voice-mail systems are designed to respond to DTMF after the system has answered the incoming calls. The tasks described in the following sections are required:

•Configuring DTMF Patterns on the Router (required)

•Configuring Integration Files on Legacy Voice-Mail Systems (required)

Note Foreign Exchange Office (FXO) hairpin forwarded calls to voice mail must have disconnect supervision from the central office.

Configuring DTMF Patterns on the Router

The Cisco SRS Telephony router provides flexibility for the integration with any legacy voice-mail system. You can configure multiple tags and tokens for each pattern, depending on the voice-mail system and type of access. The tag in the configuration pattern must match the number defined in the voice-mail system's integration file to identify the type of call. The keywords—CGN (calling number), CDN (called number), and FDN (forwarding number)—define the type of call information sent to the voice-mail system.

SUMMARY STEPS

1. vm-integration

2. pattern direct [tag1 {CGN | CDN | FDN}] [tag2 {CGN | CDN | FDN}] [tag3 {CGN | CDN | FDN}] [last-tag]

3. pattern ext-to-ext busy [tag1 {CGN | CDN | FDN}] [tag2 {CGN | CDN | FDN}] [tag3 {CGN | CDN | FDN}] [last-tag]

4. pattern ext-to-ext no-answer [tag1 {CGN | CDN | FDN}] [tag2 {CGN | CDN | FDN}] [tag3 {CGN | CDN | FDN}] [last-tag]

5. pattern trunk-to-ext busy [tag1 {CGN | CDN | FDN}] [tag2 {CGN | CDN | FDN}] [tag3 {CGN | CDN | FDN}] [last-tag]

6. pattern trunk-to-ext no-answer [tag1 {CGN | CDN | FDN}] [tag2 {CGN | CDN | FDN}] [tag3 {CGN | CDN | FDN}] [last-tag]

DETAILED STEPS
Command

Purpose
Step 1
vm-integration

Example:
Router(config) vm-integration
Enters voice-mail integration mode and enables voice-mail integration with DTMF and analog voice-mail system.
Step 2

pattern direct [tag1 {CGN | CDN | FDN}] [tag2 {CGN | CDN | FDN}] [tag3 {CGN | CDN | FDN}] [last-tag]

Example:

Router(config-vm-int) pattern direct 2 CGN *

Configures the DTMF digit pattern forwarding necessary to activate the voice-mail system when the user presses the messages button on the phone.

•The tag attribute is an alphanumeric string fewer than four DTMF digits in length. The alphanumeric string consists of a combination of four letters (A, B, C, and D), two symbols (* and #), and ten digits (0 to 9). The tag numbers match the numbers defined in the voice-mail system's integration file, immediately preceding either the number of the calling party, the number of the called party, or a forwarding number. The Cisco SRS Telephony router supports a maximum of four tags.

•The keywords—CGN, CDN, and FDN—configure the type of call information sent to the voice-mail system, such as calling number (CGN), called number (CDN), or forwarding number (FDN).

Step 3

pattern ext-to-ext busy [tag1 {CGN | CDN | FDN}] [tag2 {CGN | CDN | FDN}] [tag3 {CGN | CDN | FDN}] [last-tag]

Example:

Router(config-vm-integration) pattern ext-to-ext busy 7 FDN * CGN *

Configures the DTMF digit pattern forwarding necessary to activate the voice-mail system once an internal extension attempts to connect to a busy extension and the call is forwarded to voice mail.

Step 4

pattern ext-to-ext no-answer [tag1 {CGN | CDN | FDN}] [tag2 {CGN | CDN | FDN}] [tag3 {CGN | CDN | FDN}] [last-tag]

Example:

Router(config-vm-integration) pattern ext-to-ext no-answer 5 FDN * CGN *

Configures the DTMF digit pattern forwarding necessary to activate the voice-mail system once an internal extension fails to connect to an extension and the call is forwarded to voice mail.

Step 5

pattern trunk-to-ext busy [tag1 {CGN | CDN | FDN}] [tag2 {CGN | CDN | FDN}] [tag3 {CGN | CDN | FDN}] [last-tag]

Example:

Router(config-vm-integration) pattern trunk-to-ext busy 6 FDN * CGN *

Configures the DTMF digit pattern forwarding necessary to activate the voice-mail system once an external trunk call reaches a busy extension and the call is forwarded to voice mail.

Step 6

pattern trunk-to-ext no-answer [tag1 {CGN | CDN | FDN}] [tag2 {CGN | CDN | FDN}] [tag3 {CGN | CDN | FDN}] [last-tag]

Example:

Router(config-vm-integration) pattern trunk-to-ext no-answer 4 FDN * CGN *

Configures the DTMF digit pattern forwarding necessary to activate the voice-mail system when an external trunk call reaches an unanswered extension and the call is forwarded to voice mail.
Although it is unlikely that you will use multiple instances of the CGN, CDN, or FDN keyword in a single command line, it is permissible to do so.

Configuring Integration Files on Legacy Voice-Mail Systems

To configure the integration files for a legacy voice-mail system, follow the instructions in the voice-mail system's analog voice mail integration configuration guide or recommended documents. You must design the DTMF integration patterns appropriately, so that the voice-mail system and the Cisco SRS Telephony router work with each other. For a confutation example, see the "Configuration Examples for Cisco SRS Telephony V2.1" section

Configuration Examples for Cisco SRS Telephony V2.1

12.2(11)T

This command was integrated into Cisco IOS Release 12.2(11)T and implemented on the Cisco 1760 routers.

12.2(11)YT

The extension-pattern keyword was added.

Usage Guidelines

Directory numbers for the Cisco IP phones are expected to be entered in extension number format. The extension number should be greater or equal to the extension length. Otherwise, the extension number cannot be converted to a qualified E.164 number. The dialplan-pattern command creates a global prefix that can be used to expand the abbreviated extension numbers to fully qualified E.164 numbers. The dial-plan pattern is also required to register the Cisco IP phone lines with a gatekeeper. The dialplan-pattern command can resolve an incoming call with a full E.164 number to a Cisco IP phone extension number.

The extension-length keyword enables the system to convert a full E.164 telephone number back to an extension number for the purposes of caller-ID display, received, and missed call lists. For example, a company uses extension number range 5000 to 5099 across several sites, with only the extensions 5000 to 5009 present on the local router. An incoming call from 5044 arrives from the company's internal VoIP H.323 network and this call includes the calling number as 4085555044 in its full E.164 format.

The no-reg keyword provides dialing flexibility. You have the option not to register some specific numbers to the gatekeeper so that those numbers can be used for other telephony services.

When the called number matches the dial-plan pattern, the call is considered a local call and has a distinctive ringing identifying the call as internal. Any call that does not match the dial-plan pattern is considered an external call and has a distinctive ringing different from the internal ringing. The valid dial-plan pattern with the lowest tag is used as a prefix to all local Cisco IP phones.

The number of extension-pattern characters must match the extension length. For example, if the extension length is three, then the extension-pattern can be 8.., 1.., 5.., and so forth.

Examples

The following example shows how to create dial-plan pattern 1 for extension numbers 5001 to 5099 with the telephone prefix starting with 408555. If the following example is set, the routers recognize that the 4085555044 matches dial-plan pattern 1, and uses the extension-length keyword to extract the last four digits of the number 5044 and present this as the caller ID for the incoming call.
Router(config)# call-manager-fallback
Router(config-cm-fallback)# dialplan-pattern 1 40855550.. extension-length 4 no-reg
In the following example the dialplan-pattern command creates dial-plan pattern 1 for extensions 801 to 899 with the telephone prefix starting with 4085559. As each number in the extension pattern is declared with the number command, two POTs dial-peers are created. In the example, they are 801 (an internal office number) and 4085579001 (an external number).
Router(config)# call-manager-fallback
Router(config-cm-fallback)# dialplan-pattern 1 40855590.. extension-length 3 
extension-pattern 8..
Router(config-cm-fallback)# phone-dn 1
Router(config-ephone-dn)# number 801

Usage Guidelines

The pattern direct command is used to configure the sequence of DTMF digits passed to a voice-mail system attached to the Cisco IOS Call Transfer and Forward Supplementary Services router through one or more voice ports. When a call is placed directly from a Cisco IP phone attached to the Cisco IOS Call Transfer and Forward Supplementary Services router, the voice-mail system expects to receive a sequence of DTMF digits at the beginning of the call that identify the mailbox of the user calling the voice-mail system accompanied by a string of digits indicating that the caller is attempting to access the designated mailbox in order to retrieve messages.

Although it is unlikely that you will use multiple instances of the CGN, CDN, or FDN keyword in a single command line, it is permissible to do so.

Examples

The following example sets the DTMF pattern for a calling number ($CGN) for a direct call to the voice-mail system:
Router(config) vm-integration
