I have the following questions on 22.1 (page 194) of RFC3261. "UACs creating an ACK message will duplicate all of the Authorization and Proxy-Authorization header field values that appeared in the INVITE to which the ACK corresponds."
1. What does "will duplicate" mean? Is it same as MUST duplicate? 2. Will proxies sending an ACK for a non-2xx response also do this duplication? 3. Why is this not specified as a MUST for proxy-generated CANCELs, as well? _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
