[Asterisk-Users] TDM2400P with echo canceller not working

[Giorgio Incantalupo]

Hi,
I have  a box with Debian Sarge, Asterisk 1.2.1 (and zaptel 1.2.1) and a 
TDM2400P with echo canceller. I installed the card but no echo 
cancellation is being made...seems like the echo canceller module does 
not work, infact the software cancellation is working.

My zapata.conf has echocancel = 128 and echocancelwhenbridged = yes but 
no echotraining parameter which gives a warning.

I found no info about how to use this card and how to correctly set 
zapata.conf, which zaptel version to use, etc...

Does anybody knows how to use this card?

TIA
