Seems related to Perfect Forward Secrecy  https://hacks.mozilla.org/2015/02/webrtc-requires-perfect-forward-secrecy-pfs-starting-in-firefox-38/

I have a small patch that fixed Firefox Developer Edition for me.  Waiting for the CLA to get approved so I can submit it.

> Whenever calling a webrtc peer which uses firefox version 39 (or 40 beta), I get  error messages like "res_rtp_asterisk.c: DTLS failure occurred on RTP instance '0x7fefe800e9e8' due to reason 'no shared cipher', terminating" after the SDP exchange, and the call terminates.
> Hopefully you can reproduce it yourself on the latest version of asterisk by using
> http://www.sipml5.org/call.htm (I'm not sure if asterisk is doing anything wrong or just firefox/sipml5)
> I will provide more info if it's not easily reproducable.
