H.323 Tunneling
The H.245 protocol is a control protocol that manages the media sessions. It is a part of the
H.323 protocol suite. The H.245 protocol is used primarily to negotiate the master-slave
relationship between communicating systems. The H.245 messages can be encapsulated and
carried between H.225 controlled system within H.225 messages. This way of "piggy-backing"
an H.245 message to the H.225 message is referred to as H.323 Tunneling. The tunneling feature
relies on H.225 system-to-system connectivity (via TCP) to pass H.245 messages, and uses the
H.225 communication channel without creating a separate TCP socket connection (per H.323
call) for media control.
