Configuring
Both PBXs in this example use E&M interface Type 2, with
In this example, West users can dial 5 and a
The West router connects to the PBX through an E&M VIC port 0/0. This port is associated with a POTS dial peer for incoming calls. But you no longer need to associate every telephone number with its own port. Instead, you can configure a local dial peer as if all the West telephones (represented by a wildcard destination pattern) are connected directly to this port, as shown in the following commands:
West> enable
Password:
West# configure terminal
West(config)#
Configure VoIP dial peers for outgoing calls and associate destination phone numbers on the East router with that router IP address, as shown in Figure 20, and in the following commands:
West(config)# | voice 121 voip |
session target ipv4:192.168.11.3 | |
exit | |
West(config)# |

Now configure number expansion so that numbers beginning with 5 (belonging to the East office) and sent by the West PBX to the West router are expanded into the full destination pattern:
West(config)# | 1919555.... |
Note You do not need to configure number expansion for calls from one West telephone to another West telephone because the PBX switches those calls.
Finally, enter the following global configuration
West(config)#
