Thanks for that. We're using G.729 over H.323, incoming and outgoing.
Outgoing works perfectly but on incoming we get the underwater sound
periodically. It clicks in randomly but once there the only way to clear it
is to end the call and try again.

One thing we have thought of is co-loing an * box directly at the Telco and
plugging in to their switch directly. We'd then be in control of the VoIP
part and know that over IAX it would work fine. Can anyone enlighten me as
to how we'd connect to them physically on-site? Would it be a PRI or would
there be a different method as the PSTN wouldn't be between us and their
switch?
