I have a T1 PRI terminated in a 2821 router. It has a 100 number DID block. There is a H.323 gateway between the router and a IP Fax server. There is also a H.323 gateway to the call manager and also MGCP gateway to the call manager. I want to use some DID numbers for sending it to fax server and some DID numbers to be sent to the CCM for call processing. In this scenario, is it possible to use H.323 for the fax purpose and H.323,MGCP for calls to the CCM? In other words, can a router have both H.323 and MGCP running together where we can say what protocol needs to do what?
