I agree. However some of the workarounds are why a UAS does silly things like sending a modified SDP within 18x/2xx which must be ignored. It allows a compliant UAC to ignore it while a non compliant UAC potentially treats it as an updated answer SDP (as a workaround for lack of support/use of 100rel, UPDATE, and/or forking) instead of sticking head in the sand until SIP's offer/answer rules allow for proper subsequent renegotiation. _______________________________________________ Sipping mailing list https://www.ietf.org/mailman/listinfo/sipping This list is for NEW development of the application of SIP Use sip-implementors@xxxxxxxxxxxxxxx for questions on current sip Use sip@xxxxxxxx for new developments of core SIP
