We are using the cards successfully with Zap 1.2.4 and Zap 1.2.5, but
I've never tried it with 1.2.1. The echo keywords are sensitive as to
where they are placed in the file. If you are still getting echo after
turning that on, I would start tweaking the rxgain and txgain.
The settings I've found that work the best so far are as follows:
## /etc/asterisk/zapata.conf ##
[channels]
echocancel=yes
echocancelwhenbridged=yes
echotraining=yes
<omitted>
group = 1
channel => 1-20
group = 2
context = fax
channel => 21-24

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
Giorgio Incantalupo
