5. H.323 uses a single fixed TCP port (1720) to start a call using the H.225 protocol (defined by H.323 suite) for call control. Once that protocol is complete, it then uses a dynamic TCP port for the H.245 protocol (also defined by the H.323 suite) for capabilities exchange (caps exchange) and channel control. Finally, it opens up two dynamic UDP ports for each type of media that was negotiated for the call (audio, video, far-end camera control, etc.). This first port carries the RTP protocol data (defined by the H.225 specification) and the second one carries the RTCP data (defined by the H.225 specification).
