[Freeswitch-users] Firefox WebRTC 'fingerprint' SDP attribute missing 200OK response

Wed Jul 10 20:44:52 MSD 2013

I have a recolection there is a way to turn that off in the js settings.  I would compare to what we have running on webrtc.freeswitch.org.  I can't recall the setting off the top of my head.

One difference I did notice in the offer INVITE for the Freeswitch web site media transport attribute (m=audio 51710 UDP/TLS/RTP/SAVPF 109 0 8 101) contains 'UDP/TLS' where as in my version these two protocols are missing.  Really note sure if that is an issue but it is a difference.

I completed a similar WebRTC call via Freeswitch website 'https://webrtc.freeswitch.org/sipml5/' and the 'fingerprint' SDP attribute exists.  Am I missing an configuration setting?
