POTS Dial-Peer Configuration

The administrator must know how to identify the far-end voice-enabled device that will

terminate the call. In a small network environment, the device may be the IP address of the

remote device. In a large environment, identifying the device may mean pointing to a Cisco

CallManager or gatekeeper for address resolution and Call Admission Control (CAC) to

complete the call.

You must follow these steps to configure VoIP dial peers:

How to Configure VoIP Dial Peers

Step Action

1. Configure the path across the network for voice data.

2. Specify the dial peer as a VoIP dial peer.

3. Use the destination-pattern command to configure a range of numbers reachable by the

remote router or gateway.

4. Use the session target command to specify an IP address of the terminating router or

gateway.

5. Use the remote device loopback address as the IP address.

The dial peer is specified as a VoIP dial peer, which alerts the router that it must process a call

according to the various parameters that are specified in the dial peer. The dial peer must then

package it as an IP packet for transport across the network. Specified parameters may include

the codec used for compression (VAD, for example), or marking the packet for priority service.
