[asterisk-users] Has anyone succeeded in making a WebRTC call from Mozilla Nightly to Asterisk?

[Miguel Oyarzo]

You have to load the module res_srtp (secure media) in Asterisk.

 > module load res_srtp.so

(this is a requirement to talk websocket)

If you don't have it, must build it and install it.

Cheers,
