Try this link for an overview of IP-IP Gateway. It is titled Cisco CallManager to H.323 Service Provider Connectivity.

You will then need to simply add the H323 GW into CCM. Don't forget to Bind your H323 signalling to a specific address. Also replace your default inbound voip dialpeer.

only think jgolia hasn't mentioned in his good advice, is that you also need a different image (the IP-to-IP gateway one) on the 2811. These image names ends in _ivs. Cisco requires a license too.

The alternative is to enable direct IP communication between CCM and the h323 service provider.
