[Freeswitch-users] Significant audio clipping when bridging webrtc to sip

[Anthony Minessale]

It all depends if the endpoint you are using actually tries to establish
media on a 183.  The dtls negotiation needs time.  You should try master
instead of 1.4 if you are playing with webrtc because there are many
changes going on the 1.4 is probably actually less stable in some cases.

If no media exchange is going on the dtls can't setup so all you can really
do is explicitly answer the WebRTC call before bridging to SIP or work on
getting media to actually flow during early media stage with the sipml5
guys.
