If you're getting echo of your own voice, but the remote is getting a
clear signal, then Asterisk echo cancellation is working properly.  It
is the remote provider not echo cancelling properly.

Think of the echo in this way:  what you're hearing is your voice on
the remote receiver being picked up by the remote microphone and
sent back to you.

You might ask your remote party not to use a speakerphone and to
press the receiver tightly against his/her ear, as this will dampen the
sound detected by the microphone and lessen the echo.
