I hate to tell you this, but if you have turned on the aggressive suppressor 
you aren't cancelling echo.  You have turned your phone into a half-duplex 
communication medium.  With the aggressive suppressor enabled, when zaptel 
detects you talking, it MUTES the received audio.

Try it -- call up a friend and ask him to burp the alphabet.  While he's doing 
that, talk to him.  You will stop hearing him whenever you talk.
