H.323 Configuration for Multiple Remote sites

[pndscm]

I have many remote sites (> 20). I have them presently set up so that any remote can exit any other remote Gateway's local lines (Toll ByPass) using MGCP.
I have complaints that no one is getting incoming CallerID from the local lines. (FXO CallerID doesn't work with MGCP) My thought is to move the Gateways to H.323 to correct this but I'm concerned. Do I have to explicitly define all the remotes' local NPA-NNX's in every Gateway with a VoIP dial peers pointed to each Gateway or can I put a blanket wildcard VoIP dial peer pointed to CCM and have CCM decide where the call needs to go? With in excess of 700 NPA-NNX combinations, this could become an administrative nightmare if I have to define all of them everywhere.

Never mind, I got my answer.

Just a word of caution on H.323 and caller ID. The incomming call will hear 2 to 3 rings before the Call Manager process the call and the intended phone begains to ring. The H.323 gateways are slow in processing the caller id string.
