[Freeswitch-users] sip to webrtc - sdp invalid description

Thu Jul 13 03:24:50 UTC 2017

Hi David,

I have:

[iOS/Android app with Linphone SIP stack] <-> Kamailio <-> FS <-> Kamailio
<-> [WebRTC]

And it works correctly in all combinations (both Kamailios are only
signalling, rtp goes from clients to FS directly).

Tomorrow i'll send you the combination of codec parameters we are using so
you can compare, we can do more tests from there with the traces.

Joel.
