I thought that I had the echo problems licked but after a reboot they came back. I have run fxotune -i before and there is a /etc/fxotune.conf file and I have a backup of it. However the echo problems came back after being gone for months. I ran fxotune -i and the compared the backup fxotune.conf with the new one and there is no difference, but the echo is gone.

Do the TDM modules just like attention ever few months??

Not normally :) but make sure that fxotune -s is successfully run somewhere appropriate in the init scripts (they are run at startup, I suspect in your case you are possibly running it after asterisk starts.), but there are a couple of settings (rxgain= and txgain= in the zaptel or dahdi conf file depending)) that can sometimes make it easier for fxotune and whatever E.C. methodology you use to do their job.
