Hello Francois,
this is my zaptel.conf:
# 12 red modules (FXO) on tdm2400
fxsks=1-12
fkoks=13-16
defaultzone=it
loadzone=it
This is my zapata.conf:
[channels]
context = outbound_zap
canpark = yes
echocancel = 128
echocancelwhenbridged = yes
faxdetect = incoming
language = us
musiconhold = default
signalling = fxs_ks
callerid = "FGA" <0293500178>
channel => 1
... the same for all FXO channels, haven't specified FXS channels until
FXO ones work correctly
I haven't seen any led on my echo cancellation module...sorry!

I think it is all right...
Another question for you:
which kind of test or instrument do you use to analyze echo on analog
lines? I've heard about ztmonitor but I do not know exaclty what it does
and infos on internet are not many. Or do you use something else? If I
hade some sort of instrument for measuring echo my work on it could be
easier instead of changing randomly rxgain, txgain and all the other
parameters.
TIA

Hello Giorgio,
I am a TDM2400 happy user. :-)
Could you show your zaptel.conf zapata.conf config files ?
Think to tell us how many modules you have and where they are plugged on the
TDM2400P.
Are the leds on the echocan modules running as a LasVegas casino (scrolling
in a circular pattern) ?
If you have an echocan module aboard and well running you must see it at
Linux boot (syslog):
The 4 echocan chipsets are sequencialy checked and return an hexadecimal
code different of "FF" if ok, just before to tell "VPM: Present and
operational (Rev X)", if I remember well.
If the VPM is ok, zaptel echocan software is automaticaly disabled for this
zap channels in Asterisk server.
The echotraining is not applicable for this card and generate an error
message on the Asterisk console if enabled in your zapata.conf, but don't
care, this doesn't affect Asterisk and the call itself.
The settings must be done as usual with TDM400 cards.
I hope this can help a little.
Best Regards,
Francois BERGERET,
France.

Objet : [Asterisk-Users] TDM2400P with echo canceller not working
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
