Hi,

...

>P.P.S. Regardless of what we do, we do need the mux exclusive document. Upon more careful re-reading of RFC5761 it looks like it requires for the offerer to provide a fall back RTCP destination when rtcp-mux is not accepted.

That's why I've been saying the whole time - and that's the reason I wrote mix-exclusive to begin with :)

>We need to update the rtcp-mux-exclusive draft to make sure it updates RFC5761 to allow offers without RTCP fallback destination.

Currently, the draft defines that, in addition to the new attribute, you also insert the rtcp-mux attribute. So, if we keep that, I guess we would need to add something to 5761.

But, if we ONLY include the new attribute (I got the impression that's what people prefer), there is no need to update 5761.

Regards,

Christer
