If it is a plain H323-H323 call then there should not be any echo at all.

If you have a PSTN<->VoIP call and the PSTN leg uses analog lines then the PSTN side will create an echo which will be cancelled by the PSTN side of the gateway.

In my experience, most echo comes from the FAR end analog loop, not your local analog loop.
