h323 fast start

pl explain about h323 fast start & h323 slow start ?


  • H.323 signalling consists of 4 steps - SETUP, CALL PROCEEDING, ALERTING, CONNECT.

    After this, the H.245 media negotiation (IP address, codec, UDP port) is perfomed using a separate TCP connection. If using H.323 fast start, the H.245 media negotiation is performed within the initial SETUP message.
