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



A sysadmin that is so inaccurate as to say 500Mb instead of the obvious 512 Mb?



I think  there is no differents  for my problem.
Thank you a  lot.

- 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.



Can you verify you are using g729. Also what kind of network are you doing the IAX call over? What else is on the network at the time of the call.

Most of what you say sounds a lot like you are running short of
bandwidth. Sounds like the classic problem of running out of the
buffered content and decoding what you have when you get it.




Yes of course  I am  using   g729b  codec.
I have  SHDSL  line  with 128 bit/c bandwidth.
Nothing else  on the network in testing time.
