Why don't you record the call at asterisk? Leave the zaptel settings as 
default, i.e. standard echo cancel and rxgain=txgain=0. Don't use 
MixMonitor, just leave everything as in and out. It will help you 
isolate whether it's PSTN echo. If you don't hear any echo in the 
recording, then the problem is most likely your phone.
