Hi Christer, Thanks for generating the draft. The following are a few comments and questions. -brett ------------- Various sections mention "successfully updated" or "successfully changed" (some spelled "sucessfully") as the criteria to not rollback the modified session parameters. The meaning should be explicitly defined concerning being tied to offer/answer rules and/or other criteria. Section 1 last sentence indicates that the same applies to other parameters (non session parameters); however such normative statements are missing from section 6. What are the successfully updated/changed rules concerning non session parameters (such as Contact)? I find the section 5 "unclear" statement humorous; however I guess that it helps subdue complaints about the fix shown within section 6.1 not being backward compatible. :) _______________________________________________ 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
