Construct a table similar to Table 10 for your own routers, assigning your own telephone numbers, IP addresses, and dial-peer tags.

Note The IP addresses shown in this guide are meant only as examples. When you configure your network, be sure to substitute your own IP addresses.

Enter the following information on the West router to create the dial-peer configuration given in Table 10:

West(config)# dial-peer voice 501 voip

West(config-dial-peer)#destination-pattern 1919555....

West(config-dial-peer)#session target ipv4:192.168.11.3

Cisco IOS software describes the remote network as the session target. This command is followed by the IP address of the remote router. The prefix ipv4 means IP version 4. Alternatively, you can use the prefix dns followed by the Domain Name System (DNS) name as follows:

West(config-dial-peer)#session target dns:voice.eastrouter.com

Configure a dial peer on each router for each telephone number on every other router connected to it.

Make things easier by configuring number expansion for East router telephone numbers on the West router:

West(config)# num-exp 5....

1919555....

Now users can dial a five-digit extension beginning with 5 from a telephone on the West router to reach a telephone on the East router.

These commands are summarized in Figure 16.
