Debug Messages and Show Commands on the Cisco IOS Gateway

In the previous section, the Cisco IOS Gatekeeper show commands and debug outputs were discussed in detail. This section focuses on the debug output and show commands on the Cisco IOS Gateway. In the topology for this case study, calls are going through the

Cisco IOS Gateways. The Cisco IOS Gateway interfaces to the PSTN or PBX with either T1/CAS or T1/PRI interfaces. Debug output of commands such as debug voip ccapi inout, debug h225 events and debug h225 asn1, are shown below.

In the following debug output, the Cisco IOS Gateway is accepting the TCP connection request from Cisco CallManager (172.16.70.228) on port 2328 for H.225.

*Mar 12 04:03:57.169: H225Lib::h225TAccept: TCP connection accepted from 172.16.70.228:2328 on socket [1]

*Mar 12 04:03:57.169: H225Lib::h225TAccept: Q.931 Call State is initialized to be [Null].

*Mar 12 04:03:57.177: Hex representation of the received TPKT03000065080000100

The following debug output shows that the H.225 data is coming from the Cisco CallManager on this TCP session. Important to notice in this debug output is the protocolIdentifier, which indicates the H.323 version being used. The following debug shows that H.323 version 2 is being used. The called and calling party numbers are also shown.
