In the following example, the leading prefix digit for the 3-digit extension numbers is transformed from
0 to 4, so that the extension-number range becomes 400 to 499.

In the following example, the dialplan-pattern command creates dial-plan pattern 2 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 4085559001 (an external number).

Enabling Digit Translation Rules
Digit translation rules can be enabled during Cisco CallManger fallback. Translation rules are a
number-manipulation mechanism that performs operations such as automatically adding telephone area
codes and prefix codes to dialed numbers. Translation rules can be used as follows:
• To manipulate the answer number indication (ANI) (calling number) or dialed number identification
service (DNIS) (called number) digits for a voice call.
• To convert a telephone number into a different number before the call is matched to an inbound dial
peer or before the call is forwarded by the outbound dial peer.
To view the translation rules configured for your system, use the show translation-rule command.
Note Digit translation rules have many applications and variations. For further information about them, see
the “Configuration Dial Plans, Dial Peers, and Digit Manipulation” chapter of the Cisco IOS Voice,
Video, and Fax Configuration Guide, Release 12.2.
If you are running Cisco SRST 3.2 or a later version, use the configuration described in the “Enabling
Translation Profiles” section on page 66 instead of using the translate command as described below.
Translation Profiles are new to Cisco SRST 3.2 and provide added capabilities.
