Someone online mentioned separate cert file (dtls-srtp.pem dtls-srtp.pem to DTLS). Do I need to put add something to dtls-srtp.pem ? My dtls-srtp.pem was there by default said:I think, You should use the same cert and key, which are used for SIPS, priv key on top, cert file on bottom.
I have done personally some dialplan add ons since fusion4.0 to allow WEBRTC almost out of the box. You will need to deal with endpoints,since webrtc doesnt use user/, i dont remember by hard, but it uses other. Google it, you will find it. After that, you will need to do some dialplan configuration so allow WEBRTC to ring in the web browser and in the sip extension as well (if you want to support them both)
