> Oh excellent, then it's a "No Plan" for SRTP as well.  Cool.

Hi Hadriel,

Actually this isn't correct.  The plan of record for this is DTLS/SRTP:

Once the DTLS handshake has completed, the keys are exported [RFC5705
and used to key SRTP for the media channels.

If you think that plan isn't clear enough in the security architecture and
security documents,
suggested text would be welcome.  The point of an SDES discussion wasn't to
create an
initial plan, in other words, or event to discuss changing the existing
plan, but to consider
whether other options were to be included.

We haven't set an agenda for Berlin, but the obvious thing to do here is
not to wait, but to kick of the discussion on the list with a draft
proposing what you want to see; or, as I said below "Working group
discussion on the point, and documents addressing it, are welcome at this
point, if folks do want to re-open the topic in this venue. "

best regards,
