[asterisk-users] TDM400P periodic sound clicks on FXS

[Costa Tsaousis]

Hi,

I am having periodic sound clicks (2-3 per second) on all FXS of a 
TDM400P when the remote end is my VoIP provider. However:

- recording the conversation on the asterisk, does not have the 
glitches, although I can hear them on a real phone.
- My VoIP provider to my VoIP phones through the same asterisk is OK.
- TDM to TDM through the same asterisk is OK.

I tried with and without echocancel and different values of echotrain 
(including 'no'), without luck.
The card is not sharing interrupts.

Any ideas?



Kernel is 2.6.9
asterisk is 1.2.19-BRIstuffed-0.3.0-PRE-1y-h
