For your information, H323 Gateways do not register with CCM as they do with MGCP.

You can obviously debug h323 h225 to verify whether you see messages from CallManager, however it would be easier to configure the H323 gateway name in CCM with the IP address with which you binding h323.

Although the gateway status is always shown as unknown, the IP address should be shown if you configure the endpoint as above, this indicate that both are communicating.
