That is correct but here we are mixing network behavior with UAC behavior. UAC can send such MESSAGES, 3261 does not restrict UAC.

If the UAC sends: - INFO "1" (CSeq 101) - INFO "2" (CSeq 102) - INFO "3" (CSeq 103) and it doesn't wait for each transaction to be terminated, then if the third request (CSeq 103) arrives before the others, the others will be rejected when arriving (since CSeq is less than the last received: 103). -- Iñaki Baz Castillo <i...@aliax.net> _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
