Call routing configuration between CME routers

Dial peers are used to identify call source and destination endpoints and to define the characteristics applied between two CME routers. The destination pattern, configured in a dial peer by using the destination-pattern command, associates a dialed string with a specific telephony device. If the dialed string matches the destination pattern, the call is routed to the remote dial peers. You have to configure a destination pattern for each voice-network dial peer that you define on your network routers.

The destination pattern can be either a complete telephone number or a partial telephone number with wildcard digits, represented by a period (.) character. Each "." represents a wildcard for an individual digit that the originating router expects to match. For example, if the destination pattern for a dial peer is defined as "555....", then any dialed string beginning with 555, plus at least four additional digits, matches this dial peer.
