we had the same problem, call manager clusters need to talk to each other via intercluster trunks so if you use ios gateways basically the call managers do not know where the call has come from. if you have to sites connected via a WAN you do not need a H323 gateway this is only needed to talk to the pstn or a PBX etc
It seems to me like you are trying to tandem switch voip calls on a router. You can't do this and really don't need to. For intercluster calls point the gateway at each of the other callmanager IP addresses. You don't need to send the call to the router. The only time you would really send the call to the router is if it had a voice interface that you wanted to send the call out. The would be a voip to pots call. You can't do voip to voip calls on a normal gateway.
