Document: draft-ietf-avtext-rtp-grouping-taxonomy-07 Reviewer: Robert Sparks Review Date: 6 Jul 2015 IETF LC End Date: past IESG Telechat date: 9 Jul 2015 Summary: Ready for publication as an Informational RFC Thanks for addressing the comments I made at LC. Very small nit: I still worry that with "at least some content ... at some point during its lifetime" that you are improperly excluding streams that may never send RTP packets (because of silence suppression or the way a codec works), when RTCP will be sent. This could happen in a multimedia situation where multiple microphones are signaled, but one just happens to never get used for example.
