If you say it like that, can a UAC ignore the "real" SDP answer, if it received a precursor of the SDP answer in an unreliable response? Imagining that I am such I-am-a-new-implementor-and-I-would-like-to-get-it-right-from-the-beginning: - What answer shall the UAC take if they are different? I would expect that the rule be lenient on what you receive and be strict in what you send out also applies here, so just killing the session is not an option. Intuitively I would say take the "real" answer as that is probably the best you can get? /Hans Erik van Elburg _______________________________________________ Sipping mailing list https://www.ietf.org/mailman/listinfo/sipping This list is for NEW development of the application of SIP Use sip-implementors@xxxxxxxxxxxxxxx for questions on current sip Use sip@xxxxxxxx for new developments of core SIP
