We are in the middle of designing a similar solution with Kamailio and rtpengine and after some initial problems things are going really well. I can tell you that we ended up going with SIPjs over JSSip and it handled a lot of the weird browser specific issues we were having.
I'm not sure about the media description error, however, the crypto error is probably not a real issue. Richard explained it here: http://lists.sip-router.org/pipermail/sr-users/2014-December/086271.html I corrected the other issues I was having and that one seemed to resolve itself.
