Cisco Catalyst 4000 Access Gateway Module Installation and Configuration Note
OL-3008-01
Chapter 5 Configuring the Voice Interfaces
ISDN BRI Configuration (H.323)
gateway (config-if)# isdn spid1 spid-number [ldn]
gateway (config-if)# isdn spid2 spid-number [ldn]
Note Although the LDN is an optional parameter in the command, you might need to enter it so the
gateway can answer calls made to the second directory number.
For further information on configuring ISDN, refer to the chapters “Configuring ISDN” and
“Configuring DDR” in the Wide-Area Networking Configuration Guide publication.
BRI Direct-Inward Dialing Configuration
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 AGM 1 on the BRI port. The DID information allows the AGM to
route the call based on the called number. If the called number is 2xxx, the call is routed to AGM 2000;
if the called number is 3xxx, the call is routed to AGM 3000.
Figure 5-1 illustrates the topology of this connection example.
