No UAC will send a CANCEL for a non-INVITE transaction. Of course it could occur, and also a UAC could send a request with method CHICKEN XDDD But if I receive a not-matching CANCEL I will consider that the INVITE associated to that CANCEL hasn't arrived yet. So the reply would be 484. -- Iñaki Baz Castillo [EMAIL PROTECTED] _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
