[JRE] According to Dean's definition of RT, it does not change the Request-URI (only the Route header field presumably, or maybe not even that). So C, D and E are the same. Also A and B are the same, and F and G are the same. So I think: - UA-Loose-routing gives you C/D/E - To gives you A/B - PCPID gives you C/D/E - Target gives you C/D/E - Hist-info gives you A/B, C/D/E and F/G. > > -hadriel > > > > _______________________________________________ > Sip mailing list https://www1.ietf.org/mailman/listinfo/sip > This list is for NEW development of the core SIP Protocol > Use [EMAIL PROTECTED] for questions on current sip > Use [EMAIL PROTECTED] for new developments on the application of sip > _______________________________________________ Sip mailing list https://www1.ietf.org/mailman/listinfo/sip This list is for NEW development of the core SIP Protocol Use [EMAIL PROTECTED] for questions on current sip Use [EMAIL PROTECTED] for new developments on the application of sip
