[Nice] Can't get TURN candidates

Fri Jun 28 02:00:14 PDT 2013

Hi Youness,

Thanks for your answer.
The wiresharks captures are quite relevant (well, I guess) :

   - with the stun : 1. binding request, 2. allocation request, 3. binding
   response, 4. 5. 6. : allocate requests.
   - with the turn :  1. binding request, 2. allocation request.. and the
   same three times more, but no response from the turn.

I already changed the compatibility to google mode for the stun, as it
didn't work with the RFC compliant at first.
The basic application works with libjingle. I have no more information
about the compatibility..
I didn't set up the server, and nobody seems to be able to answer this
question at work. ;)
I join the two output of the simple-example (with stun and turn), if it can
help.
