Hi I have reviewed this document as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review. Document editors and WG chairs should treat these comments just like any other last call comments. Document Reviewed: draft-ietf-mmusic-mux-exclusive Status: Ready Summary: This draft defines a new SDP media-level attribute, 'rtcp-mux-only' to indicate exclusive RTP/RTCP multiplexing. It also updates RFC5761 with clarifying statements. I found the document well put together, and I especially found the section on the updates to RFC 5761 very well done, and a nice example for others. tim
