I recently upgraded my Asterisk system to Dahdi and now I have an echo
<br>
problem.
<br>
<br>
I am running Asterisk 1.4.25 with Dahdi Complete 2.2.0, on a Digium
<br>
TE121B PCI express card with a HARDWARE echo cancellation module. All
<br>
this is housed on a CentOS 5.5 box, 2.6.18 Kernel. My incoming phone
<br>
service is an AT&T PRI (24 channel T1).
<br>
<br>
My configs:
<br>
<br>
********chan_dahdi.conf*********
<br>
<br>
[channels]<br>
; configuration for T1 card as PRI<br>
language = en<br>
<br>
group = 1<br>
echocancel = yes<br>
echotraining = yes<br>
signalling = pri_cpe<br>
switchtype = 4ess<br>
usecallerid = yes<br>
context = incoming<br>
channel => 1-23<br>
<br>
<br>
***********/etc/dahdi/system.conf*************
<br>
loadzone=us
<br>
defaultzone=us
<br>
span=1,0,0,esf,b8zs
<br>
bchan=1-23
<br>
dchan=24
<br>
<br>
When I run dahdi_cfg -vvv I get the following:<br>
<br>
DAHDI Tools Version - 2.2.0<br>
<br>
DAHDI Version: 2.2.0.1<br>

It is showing MG2 as the echo canceller, even though I don't have an
echo canceller specified. Is that the harwdare module? Do I even need
to specify an echo canceller in the configs if I have a hardware echo
module?
