Technical Bulletin 11572

Changes to Local Digit Maps on SoundPoint® IP Phones

This technical bulletin provides detailed information on how to modify the configuration files to automate the setup phase of number-only calls.

This information applies to SoundPoint IP phones running SIP application version 2.1 or later.

Introduction

Enhancements have been made to this feature that can eliminate the need for using the Dial or Send soft key when making outgoing calls. For example, it can match the behavior of removing the 9 or 0 from a string of dialed digits or adding the area code before dialed digits when a switch to 10 digit phone numbers occurs.

As soon as a digit pattern matching the digit map is found, the call setup process will complete automatically. The configuration syntax is the same as that specified in 2.1.5 of RFC 3435. The phone’s behavior when the user dials digits that do not match the digit map is configurable. It is also possible to strip a trailing ‘#’ from the digits sent, prepend a ‘+’ to digits, or to replace certain matched digits with the introduction of ‘R’ to the digit map.

Configuration File Changes

If a single dial plan is used for the entire company, the dial plan is best specified in the application configuration file (sip.cfg). You can also create multiple dial plans and specify which phones are to use which in the phone-specific configuration file (phone1.cfg).

Configuration changes can performed centrally at the boot server or locally:

Central

Configuration file:

Specify impossible match behavior, trailing # behavior,

(boot server)

sip.cfg

digit map matching strings, and time out value.

 

 

For more information, refer to Dial Plan in Application

 

 

 

Configuration File on page 2.

 

 

 

 

Configuration file:

Specify per-registration impossible match behavior,

 

phone1.cfg

trailing # behavior, digit map matching strings, and time

 

 

out values that override those in sip.cfg.
