Step 9 Verify Cisco CallManager setting for the H.323 gateway to determine if the H.225 session was rejected by Cisco CallManager because the wrong IP address was configured for the H.323 gateway. Configure the correct IP address for the H.323 gateway, 172.16.13.16. For more information on CallManager configuration and IP address configuration, see the Cisco CallManager Administration Guide, Release 3.3(2) "Device Configuration" chapter, "Adding Gateways to Cisco CallManager" and "Adding a Cisco IOS H.323 Gateway" sections.

Step 10 Use debug commands to verify that the next call completes, as shown in the following partial debug output:

The following lines show that after a two-minute call, the IP phone user hangs up and the call is disconnected with normal call clearing:
