7102 and H323 Nating

Dear All,
I have two Avaya IP office PABX connected to 7102 routers.
the addresses of the Ip office are nated on the routers.
the nat is a one to one nat.
When trying to connect from one site to the other, the h323 signaling is passing, but no voice is getting through.
I think this is a problem related to nating.
did anyone face this issue before?
(When replacing the IP office by PC's network commnication is working fine).

Help is appreciated
