Enterprise Voice Routes specify how Office Communications Server 2007 R2 handles outbound calls made by Enterprise Voice users. The routes assign destination phone numbers to specific media gateways and telephone usage records. Communications Server maintains a table of outbound call routes. When a user makes a call, the server normalizes the phone number if necessary by translating it into E.164 format and trying to assign it to a SIP URI (Session Initiation Protocol, Uniform Resource Identifier). If mapping is not possible, the server applies number-based routing logic for outbound calls.

The routing table with the routing logic for outgoing calls used by the server for numbers of a private branch exchange or a public switched telephone network (PSTN) is populated with these routes.

To add a route, you must have previously deployed at least one media gateway and, if necessary, a Mediation Server, as well as a location profile and a telephone usage record. In order for a route to work, the numbers forwarded to the gateway must be located at the gateway with the gateway's administration interface.

For details about how to configure outbound call routing, see the Operations section of the Office Communications Server Technical Library.
