Configuring Voice-over-IP
Table 10
Remote Location
East
Construct a table similar to
IP addresses, and dial-peer tags.
The IP addresses shown in this guide are meant only as examples. When you configure your network, be
Note
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

dial-peer voice 501 voip
destination-pattern 1919555....
session target ipv4:192.168.11.3
num-exp 5.... 1919555....
The West router is now configured to send calls to the East router.
