Before reviewing the following traces, it is important to understand the meaning of the term H.323. By way of a brief explanation, there are several protocols that are used when establishing an H.323 session. One protocol is H.225, which is primarily used for call signaling and is a subset of Q.931. Another protocol is H.245, which is used for capability exchange. One of the more important functions of H.245 is the Compressor/Decompressor (codec) type negotiation, such as G.711, G.729, and so on, between the calling and called side. Once the capability exchange is complete, the next important function of H.245 is performing a UDP port negotiation between the calling and called sides.

The following trace shows that the H.323 code has been initialized and is sending an H.225 setup message. You can also see the traditional HDLC SAPI messages, the IP address of the called side in hex, and the port numbers.

15:20:21.421 CCMOut Message -- H225SetupMsg -- Protocol= H225Protocol

15:20:21.421 CCMMMan_Id= 1. (iep= 0 dsl= 0 sapi= 0 ces= 0 IpAddr=e24610ac IpPort=47110)

The following trace shows the calling and called party information as well as the H.225 alerting message. Also shown is the mapping of a Cisco IP Phone’s hex value to the IP address. 172.16.70.231 is the IP address of the Cisco IP Phone (1001).

15:20:21.437 CCMStationD - stationOutputCallInfo CallingPartyName=1001, CallingParty=1001, CalledPartyName=, CalledParty=3333, tcpHandle=0x5138d98

15:20:21.453 CCMIn Message -- H225AlertMsg -- Protocol= H225Protocol

15:20:21.953 CCMStationD - stationOutputOpenReceiveChannel tcpHandle=0x5138d98 myIP: e74610ac (172.16.70.231)

The following trace shows the compression type used for this call (G.711 µ -law).

15:20:21.953 CCMStationD - ConferenceID: 0 msecPacketSize: 20 compressionType:(4)Media_Payload_G711Ulaw64k

Once the H.225 alert message has been sent, the next part of H.323 is initialize: H.245. The following trace shows the calling and called party information, and the H.245 messages. Notice the TCP handle value is the same as before, indicating this is the continuation of the same call.

15:20:22.062 CCMH245Interface(3) paths established ip = e74610ac, port = 23752 15:20:22.062 CCMH245Interface(3) OLC outgoing confirm ip = e24610ac, port = 16758 15:20:22.062 CCMMediaManager - wait_AuConnectInfo - received response, forwarding

The following trace shows the H.225 connect message, as well as other information that was explained earlier. When the H.225 connect message is received, the call has been connected.

15:20:22.968 CCMIn Message -- H225ConnectMsg -- Protocol= H225Protocol

15:20:22.968 CCMStationD - stationOutputCallInfo CallingPartyName=1001,

CallingParty=1001,

CalledPartyName=, CalledParty=3333, tcpHandle=0x5138d98
