Thank you.

How do you think would be the best way to approach this problem? Do you
think anything else could also produce echo as well?

By nature, pure SIP connections will not generate echo.  This is an
acoustic problem on one or both ends.  If your client is using
headsets, make them get better headsets.  It also might be that they
absolutely love speakerphone and the room's acoustics are bad.
