The SIP dialog is creted with the INVITE and 200, regardless of the presence/abscense of the ACK, so the call must be terminated with a BYE (from the caller or called). A CANCEL from UAC is not valid as the INVITE was already accepted. -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
