I'm not exactly sure what you are asking. RFC 5373 discusses auto-answer in case you are referring to this or another mechanism.
RFC 3311 discusses UPDATE. The 500 with Retry-After text and 491 text is likely of interest to you. Your race condition is also likely discussed within RFC 5407 and/or draft-ietf-sipping-sip-offeranswer. > -----Original Message----- > From: [email protected] [mailto:sip- > [email protected]] On Behalf Of RAMESH RANGARAJAN > Sent: Tuesday, February 03, 2009 4:14 AM > To: [email protected] > Subject: [Sip-implementors] Query on UPDATE when Auto-answer is enabled? > > Hi, > > I am stuck with a scenario where Auto-Answer is enabled on the SIP Phone > and it receives UPDATE method(before session negotiation is complete) . > > Can some point out what should be the behaviour? > > Regards, > Ramesh > _______________________________________________ > Sip-implementors mailing list > [email protected] > https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
