This is with a TE411P (Digium Quad Span PRI with Voice Processing
Module). When I say pulled the zaptel trunk source, I mean I issued the
following command which pulled the latest available source code at that
time:<br>
<br>
svn checkout <a class="moz-txt-link-freetext" href="http://svn.digium.com/svn/zaptel/trunk">http://svn.digium.com/svn/zaptel/trunk</a> zaptel<br>
<br>
I followed up to a message previously with the exact trunk version that
I downloaded: SVN-trunk-r941<br>

is my last update to my issue. Finally my echo problem is
<br>
resolved. On Monday morning 2/13/06 I pulled the the zaptel trunk<br>
source. That night after my customers core business hours we built the<br>
new zaptel drivers, rebuilt libpri, asterisk, asterisk-addons. My echo<br>
disappeared almost entirely we made a few tweaks with the tx and rx<br>
gain settings. My echo problem disappeared completely with the<br>
additional tweaks to txgain. Occasionally at the very beginning of a<br>
local call echo will exist for a second or so, but then it goes away.
<br>
<br>
In two operating days there has only been one notice from a user about<br>
experiencing an echo. All the users were informed that they should<br>
notify us of any echo experiences.<br>
<br>
Here are my final configurations
