Try turning off of echotraining. Sometimes it does more harm than good.

Hi all, I have a TDM2400P w/ echo cancellation, 8 FXSs and 8 FXOs.
They are installed respectively on banks 1,2,5 and 6. The problem I am
having is that when I make a call using the ZAP channel, I can hear
perfectly but the person on the other end is hearing my voice with
lots of ticks. It would seem I am making this call over a very bad
bandwidth which is not the case since this is the PSTN. My
configuration files are below, I have the latest versions of Zaptel,
Libpri and Asterisk. I am using Polycom’s IP301 and IP430 Phones. I
would appreciate help since I have to put this in production on
Saturday.
