[Asterisk-bsd] Clicking noise on TDM400P

[Aaron Seelye]

Hello,

I have a TDM400P with 4 FXO ports, currently using one.  When sending or 
receiving calls on this card, there is a nearly constant popping/clicking 
sound, which some digging said it was 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 jack, 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'm running the latest zaptel and asterisk btw.

Thanks,

Aaron Seelye
