Can you point me to the minutes from the IETF 77 discussion where this consensus was reached ?

The discussion during the newt IETF (IETF-77) resulted in recommending only RFC5761 and "only" recommending other mechanisms. This was reflected in version -08 and was not changed in today's -09 version.

I'm not disagreeing with Magnus, just saying that the RTCP is not a problem, it's the RTP we have problems with.

This seems critical given the fact that a larger percentage of the deployed equipment does support RTCP. I think the specification needs to add back in what to do when there is not RTCP support or it needs to be brought back to the WG for discussion.
