[Nice] Fwd: compatibility with rfc5766-turn-server

[Youness Alaoui]

I just tried rfc5766-turn-server and it seems to work fine with both the
simple-example and the stun/tools/stunbdc, I'm not sure why it wouldn't work for
you.

The wireshark capture you sent shows that the server receives and responds to
the STUN request properly. The "STUN demux error: no cookie!" however doesn't
make any sense because it means it can't find the rfc5389 cookie, which means
it's trying to parse it as a rfc5389 message, but that's not logical since it's
using rfc3489 for the stun requests.

Let me know if you were able to find anything else about this problem.

Thanks,
Youness.
