Neither me! :)

Sure. The problem is: what would you do if another SIP client (i.e.
Blinks) offers you (JsSIP) an SDP with audio/video and MSRP? :)

NOTE: I have not the response for this scenario, honestly I consider a
IETF failure to allow mixing in the same SDP audio/video + MSRP.

Note however that the Session.js and MediaSession.js modifications
used yesterday in SIPit were removed later from JsSIP master branch
(they still exist in a fork in which Firefox developers have commit
rights to test Firefox's WebRTC stack). This is because changes were
applied too soon and all those changes will be refactorized soon and
commited into master.
