Here's the answer from Section 13.2.2.3 of 3261 - "A single non-2xx final response may be received for the INVITE. 4xx, 5xx and 6xx responses may contain a Contact header field value indicating the location where additional information about the error can be found. Subsequent final responses (which would only arrive under error conditions) MUST be ignored."

What should be the UAC behavior in such a scenario? - Andy Send instant messages to your online friends http://in.messenger.yahoo.com _______________________________________________ Sip-implementors mailing list Sip-implementors@cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors ********************** Legal Disclaimer **************************** "This email may contain confidential and privileged material for the sole use of the intended recipient.
