--- Not sure if I understand you. What I mean is that a UAS could send a 400 response to the INVITE transaction (so the transaction remains to absorb retransmissions and the ACK). What about if the UAS receives in that moment a CANCEL for that *still existing* INVITE transaction? -- Iñaki Baz Castillo [EMAIL PROTECTED] _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
