Note You can use the period symbol (.) to represent variables (such as extension numbers) in a telephone number.

The information included in this example needs to be configured on both Router 1 and Router 2.

Configure Number Expansion

To define how to expand an extension number into a particular destination pattern, use the following command in global configuration mode:

Command

Purpose

num-expextension-number extension-string

Configure number expansion.

 

 

You can verify the number expansion information by using the show num-expcommand to verify that you have mapped the telephone numbers correctly.

After you have configured dial peers and assigned destination patterns to them, you can verify number expansion information by using the show dialplan number command to see how a telephone number maps to a dial peer.
