Hi,

Please take a look at

http://www.voip-info.org/wiki/index.php?page=Asterisk+v1.2+upgrade+to+v1.4+gotchas

iax.conf The new threading model is great, but the default of 10 threads is
way too low. Symptoms include total loss of audio until the channel is hung
up.


   - in general section, add: iaxthreadcount = 200
   - in general section, add: iaxmaxthreadcount = 1000

Hope this helps.

Regards,
Cristian
