Dial peers establish logical connections, or call legs, to complete an end-to-end call. Cisco voice-enabled routers support two types of dial peers: –POTS dial peers: Connect to a traditional telephony network –VoIP dial peers: Connect over a packet network

Basic POTS dial-peer configuration consists of defining the dial peer with a tag number and POTS designation, defining the destination pattern, and defining the voice port to which the device is connected. Basic VoIP dial-peer configuration consists of defining the dial peer with a tag number and VoIP designation, defining the destination pattern, and defining the remote voice-enabled router through the session target command. The destination-pattern on a dial peer can utilize wildcards to simplify configuration. The default dial-peer is used when no match in the configured dial peers is found. Summary
