Configuring Direct-Inward Dialing on a BRI Port
The following example shows how to configure a BRI port for direct-inward dialing (DID). This
configuration allows the called number information from the ISDN Q.931 setup message to be used for
routing on an ISDN line.
In this example, a call comes in to router 1 on the BRI port. The DID information allows the router to
route the call based on the called number. If the called number is 2xxx, the call is routed to router 2000,
and if the called number is 3xxx, the call is routed to router 3000.
Figure 4-5 illustrates the topology of this connection example.
