[Asterisk-Users] Help with IAX , voice Distortion or Breakage.

[Alexey Ostrovsky]

Hello all,

We have the following problem:
 
When calling via iax, the sound is off after a while - most often after 
about 5 minutes (sometimes later or earlier) - at one end or at both 
ends. While the channel is up, and packages are still being transmitted, 
you just can't hear anything. Sometimes you can hear something just a 
little, but with the voice greatly distorted, sounding like a robot's 
voice.
This problem emerges whichever phone is called or whichever phone a call 
is made from (softphone, ipphone, local phones thru TDM cards)

System details:

- Linux Slackware 9.1 kernel 2.4.6
- CPU PIII 800
- RAM  500 Mb
- motherboard Asus TUSL-2c
- hard drive IDE

- Asterisk last cvs update
- 3 TDM400 cards 
- codec g729 voiceage

Help please.
May be somebody have same problem.

Thank you.
