Adding Number Expansion Sets

In most corporate environments, the telephone network is configured so that you can reach a destination by dialing only a portion of the full telephone number.  You can define an extension number as the destination pattern for a dial peer.

A number expansion set is all number expansions configured on a gateway.

Adding a number expansion set enables you to define a set of digits for the router to add to the beginning of a dialed string before passing it to the remote telephony device. This reduces the number of digits that a user must dial to reach a remote location.

Use this procedure to add a number expansion set for a zone.

Prerequisite: You must specify number expansion rules for all number expansion sets added to the dial plan.
