sip and h323 interoperability issue

Dear experts,

we have got a problem with sip and h323 interoperability, the scenario is as follows,

we have many customers connecting to our soft switching cluster, using sip support ipphones ; but on the terminating leg sessions are initiated via h323 protocol , the problem is, when a client tries to make call, he atleast needs to try 3 times for the call to be established ,in the first two trys the originatig endpoint heres the voice of called party, but the termination endpoint does not here anything .

equipments used on terminating gateways are usually cisco router 3660/3640.

I realy do appriciate any suggestions in this regard .

Best Wishes
