<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi,<br>
<br>
I do not believe I ever tried rfc5766-turn-server. I was testing with<br>
<a href="http://turnserver.org" target="_blank">turnserver.org</a> but libnice should work if the server follows the RFC.<br>
I believe Madaro did a lot more testing with TURN than I did and maybe he can<br>
provide some help.<br>
Without the code you used to setup libnice or logs, there's not much I can help<br>
you with.<br>
Unfortunately, I do not have time at the moment for libnice maintenance so I<br>
can't test it for now.<br>
If you figure out what the issue is and it's a bug in libnice, a patch would be<br>
welcome.<br>
<br>
Thanks,<br>
Youness.<br>
