Christer, >> . >> >> >> Regarding from tags there is no explicit text, but 22.2 says: >> >> When a UAC resubmits a request with its credentials after receiving a >> 401 (Unauthorized) or 407 (Proxy Authentication Required) response, >> it MUST increment the CSeq header field value as it would normally >> when sending an updated request. >> > > So, I guess that means that the second INVITE in Dale's example should > have Cseq => 3. I interpreted this as "MUST increment (relative to the INVITE being challenged)". I guess for initial INVITEs the minimal requirement is that the CSeq be different, else merged request detection (8.2.2.2) could kick in and prevent the call from succeeding. So both 2 or 3 are valid, the text is ambiguous Regards, Jeroen _______________________________________________ Sip mailing list https://www1.ietf.org/mailman/listinfo/sip This list is for NEW development of the core SIP Protocol Use sip-implementors@cs.columbia.edu for questions on current sip Use sipping@ietf.org for new developments on the application of sip
