It was me that said we where going to schedule an interim meeting. Which
we chairs failed to to in the previous cycles between meetings which was
our bad.

However, this time we have proposed a time and requested people to
submit agenda items to that meeting. Don't hold us WG chairs responsible
because you in the WG aren't providing input into what should be discussed.

I see an tendency on the mailing list to shout "Security Descriptions is
important!". But, when we ask for people willing to provide a proposal
for how to integrate it, or even provide input into a discussion that
could reach a WG conclusion that Security Description or some other
additional keying than DTLS-SRTP is desired people goes silent.

Without proposals we chairs where not seeing reasons to hold this
interim meeting.

If you want to discuss this, write a draft describing how how your
additional keying is to be integrated, what the pro and cons of it. That
will enable direct discussion of a proposal. The WG clearly are
opinionated on this matter, but apparently don't have energy to produce
