[Freeswitch-users] ICE/DTLS handshake

[Mirko Brankovic]

And I was wrong, nothnig to do with STUN,
Problem is that engine state (switch_rtp_ready(engine->rtp_session) is
false) is not ready at the moment that STUN/ICE is starting.

Not to see what is holding Audio engine to get to ready state (I'm
suspecting the TRANSCODING_NECESSARY event)
