[Freeswitch-users] WG: Turn configuration mod_sofia

Hi Brian,

we use the Freeswitch as "Man in the Middle" for WebRTC.

The WebRTC Clients (ICE Link Stack from Frozen Mountain) registered via SIP on the Freeswitch.
The SIP signalling is a special szenario and works successfully in several LAN WAN setups.
But now we need srflx (that's fine with teh STUN configuration) an relay candidates in the SDP that's ganerated by the Freeswitch.

My think is, for this case i need the possibility to configure the turn server with credentials in the sip profile like the stun configuration too.

-          STUN configuration "<param name="ext-rtp-ip" value=" stun:stun.freeswitch.org"/>"

-          ICE configuration could be? "<param name="ext-rtp-ip" value=" { 'stun:stun.freeswitch.org', 'turn:turn.myserver.com;username=xxx;password=123'}"/>"

Thanks a lot

There is little reason to use TURN when speaking to FreeSWITCH, What issue
are you trying to solve?

Betreff: Turn configuration mod_sofia

Hi all,

the stun configuration for the mod_sofia profile is very easy "<param name="ext-rtp-ip" value=" stun:stun.freeswitch.org"/>"
but what is to do, if i need a relay candidate in the sdp? How can i set the turn address and the login credentials?

Thanks a lot
