Now I test webrtc communicate with SIP Client(sx20)
I send invite message with webrtc sdp. but sip client answer has not finger print, and
sip client answer is not SRTP just RTP.
So I need to turn off SRTP in WEBRTC. Can I do it?
and one more question... I think, finger print is encrypt key,
so, sender and receiver need to each key? we need two key? sender's key, receive's key?
or we need just sender' key?
For testing purposes, Chrome Canary and Chrome Developer both have a flag which allows you to turn off SRTP, for example:
cd /Applications/Google\ Chrome\ Canary.app/Contents/MacOS/
./Google\ Chrome\ Canary --disable-webrtc-encryption
Then your SDP with the RTP setup would look more like:
m=audio 17032 RTP/AVPF 111 126
Instead of:
m=audio 17254 UDP/TLS/RTP/SAVPF 111 126
