Subject: [asterisk-users] TDM400P FXO click sounds

Hello,
 
I have a TDM400P with 4 FXO ports, currently using three.  When sending or
receiving calls on this card, there is a nearly constant popping/clicking
sound, it is related to the echo cancellation?.  I adjusted my gains
properly, but to no avail.  I even found that setting echotraining=no in
zapata.conf didn't change the scenario at all.  I've plugged analog handsets
into the same jacks, and the line is crystal-clear. Below is my zapata.conf,
if you guys have any ideas how I might resolve this, I'd appreciate it.  I
have installed from sources Asterisk 1.2.22 and zaptel-1.2.19 on a debian
etch x86_64.
