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 zaptel trunk pulled 2/13/06 approx 10:00am est.
