Hi,
I think you need to remove the line echocanceller in system.conf
You could also try to use fxotune, it'a really improving things.
You also need to put echocancel=yes in chan_dahdi.conf

If I installed a Digium echo cancellation module on my TE121 card,
do I need to remove the echocanceller line under the system.conf?
How should I have it?
This is my system.conf:
bchan=1-23
dchan=24
echocanceller=mg2,1-23
Thank you!

Internal calls should be SIP to SIP. Yes we do have the acoustic
echo cancellation active on the Polycom phones.

Yes, I believe so. I asked an Asterisk expert to make sure
everything is working correctly when installing the hardware
module. If the setting don't look correct, what should be there
when we use the hardware module?
Thank you!
