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