Subject: [Freeswitch-users] ICE -> FreeSWITCH tries exclusively the first candidate

Hi,

currently I have the problem that the FreeSWITCH only serves the first candidate from the candidate list via STUN request.

I expected it to try to reach all candidates relatively soon (trickle).

In the source code I saw that there are four ICE types:

ICE_GOOGLE_JINGLE

ICE_VANILLA

ICE_CONTROLLED

ICE_LITE

What is behind them, and how can I select them from the "outside"?

Or am I on the wrong track? What to do, that the FreeSwitch serves the candidates according to Trickle?

I have the same result for mod_sofia and mod_verto (is clear, they use the same media stack).

Thanks and greetings

Alex
