Ekr, Jonathan, et al,

We are now discussing the need for ICE updated offer (see below and the related threads on the MMUSIC list). As Flemming mentioned below, we have not yet heard opinions from everyone participating at the discussion at the previous meeting.

I tried to summarize the discussions so far also here:
https://mailarchive.ietf.org/arch/msg/mmusic/n1qOI7To4LuZRO41WGu4g702TvU

Could you please comment with your views so that we have the latest opinions from all sides.


Thanks,
Ari (as individual)

Basically want to have option to never do the updated O/A exchange, with an indication in the signaling that you will not be doing it. Of course can always initiate a new O/A exchange whenever you want to.

What I would suggest is that the author (Ari) actively engages the people that expressed an opinion at IETF 90 in this discussion to get their points of view. We can then discuss at IETF 91 again and take another consensus call based on all the information available. We will make sure to also take that consensus call to the mailing list subsequently to hopefully agree on the way forward (or at least get explicit consensus).
