Hi everybody, I followed this tutorial

https://kb.asipto.com/freeswitch:kamailio-3.3.x-freeswitch-1.2.x-sbc#kamailio_33x_and_freeswitch_12x_for_media_services_and_sbc

And it works fantastic!

The next step was to add WebRTC support, so I added WebSockets module to enable web clients to register on kamailio. It works flawlessly and webphone clients register OK! (Followed this http://nil.uniza.sk/sip/kamailio/configuring-kamailio-4x-websocket )

Now, when I call from a softphone (eyeBeam) to the web client (jssip) the other party reach okay, rings okay, but when I pickup de call (from the web client), the softphone goes directly to the VoiceMail.

From the logs I see the jssip throw this error:

"Failed to set remote offer sdp: Called with SDP without DTLS fingerprint."

I would like to avoid RTPEngine, because from what I understand, FreeSwitch can handle the media part.

Can somebody please have the kindness to guide me on how to enable webrtc between Kamailio and FreeSwitch? If somebody needs to see the "kamailio.cfg" please let me know, and i would upload the file to a gist.

Cheers,

Emanuel.
