Incoming call routes records are used to control the routing of incoming calls. Various aspects of the incoming call (for example the line it is on and the caller ID) are compared for matches to the available ICR records. The destination settings in the ICR record that is the best match are then used to route the call.

Click MSN Configuration to populate the incoming call route table with MSN or DID numbers. When you click MSN Configuration, you are prompted to specify a server.
