Hi,
I'm Asterisk newbie, and I have a big problem with echo on one of my customers sites, I have an HP AMD QUAD Core server with 1GB RAM + Digium, Inc. Wildcard TE122 single-span T1/E1/J1 card with EC: VPM150M module,
The Dahdi Version is:
lombaspbx*CLI> dahdi show version
DAHDI Version: 2.2.1 Echo Canceller:
my /etc/dahdi/system.conf looks like that:
root@pbx# cat /etc/dahdi/system.conf
span=1,0,0,esf,b8zs
e&m=1-24
loadzone = us
defaultzone = us
my /etc/asterisk/chan_dahdi.conf looks like that:
root@pbx# cat /etc/asterisk/chan_dahdi.conf

rxwink=300
usecallerid=yes
hidecallerid=no
callwaiting=no

callwaitingcallerid=yes
threewaycalling=yes

callgroup=1
pickupgroup=1
channel => 1-24
What would be the problem? Please help me out,
Thanks and Regards,
Hello,
Have you tried with echotraining=no as the training will be done by the hardware module and not the software?
Please post also the output from the following commands:
dmesg
dahdi_scan
dahdi_hardware
HTH,
Ioan
First you need to install DAHDI 2.3.0. Unload all the current dahdi drivers, then run the command ‘dmesg -c’. Then load the drivers again. Run the command ‘dmesg’ and check if it finds the VPM or not. It should use firmware version 1.20. If you have any questions please contact Digium Support.
Hi,
Thanks for your support, i’ve changed the value echotraining to no and I’m waiting results from my customer, by the other hand here is my dmesg:

On a some what related note, you will want to load the wcte12xp driver with the latency option so that it doesn’t reset several times.
modprobe wcte12xp latency=12
