ABSTRACT:
The present invention is directed generally to a system and method for monitoring a multi-party session. The system and method includes in one embodiment a matcher to match selected information in incoming RTCP packets with one or more of an orphan table and active session table and in another embodiment a first session endpoint that reflects or transmits a packet received from a second session endpoint to a session monitor. In yet another embodiment, the network address of the first and second endpoints can be included in the packet.
