Hi,

I have updated the PR. The text now says that the offer must not
*finalise* the DTLS handshake until it has received the answer.

The text still allows to process media that is received before the answer
is received. I know Martin doesn¹t like that, and I have no idea what the
sec people will think about it, but I am trying to find some common
ground. I want to move the draft forward.

Is this something everyone can live with?

Actually, before you get the SDP answer you can¹t send any DTMFsŠ
