These routes populate the routing table, which embodies the outbound call routing logic that is followed by the server for PBX and public switched telephone network (PSTN) numbers.

To add a route, you must have previously deployed Session Initiation Protocol (SIP) Trunking or at least one media gateway and, if necessary, Mediation Server, as well as a location profile and phone usage record. For a route to work, numbers routed to a gateway must be localized at the gateway, using the gateway’s administrative interface.
