Hi All, I want to know how to implement TCP connections in SIP, are there some documents describe them? I saw some people in the mailist ever discussed it, but I don't know their conclusions? I wanna know, 1) SIP client and server use one TCP connection or several separate TCP connections for sending or receiving SIP messages during a transaction procedure, i.e. sending REQUEST uses a TCP connection, and close it, and then create another TCP connection for sending RESPONSE? 2) Could each subscriber's SIP register and calls share a TCP connection? i.e., after a successful registration, SIP client will go on to keep the TCP connection for subsequent calls until de-registration? 3) If 2) yes, how about re-register process? if a TCP connection is maintained between SIP client and server, is re-register not needed yet because we could check TCP status?
please tell me your opinions or implemations about it. Thanks and Regards, JC _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
