I was told you can leave echocancel=yes with no problems, the drivers
will see it and take over if the echocancel card is present.<br>
<br>
I have found no method of monitoring echo cancellation(other than
listening for echo on live calls) without altering asterisk or zaptel
code. But there are no tools for it built in to asterisk or zaptel.<br>
<br>
Currently the echo tails are hardcoded and are not configurable. I
think it's set at 16ms for all channels on the card. Talking with
support at Digium and they said it may be an option to set it
differently in a future driver version.<br>

Hi all,<br>
<br>
1. Just bought a new TE411P and about to install it replacing the
existing TE410P. I am assuming I need to set echocancel=no and
echocancelwhenbridged=no now that it will be done in hardware, correct?<br>
<br>
2. Is there any way to monitor hardware echo cancellation to ensure it is working (apart from being on a call)?<br>
<br>
3. The Digium webite says "By supporting 16ms with 128 channels or 64ms
on 32 channels this card will perform in the most difficult of
environments.". How do I switch the echo tail size between 16ms and
64ms?<br>
<br>
<br>
Thanks.....<br>
