I am in the process of integrating the Xmedius fax server and cannot seem to get the server to communicate with the call manager. We are running CCM 4.2.3 and i have followe the Xmedius install guide. The Xmedius installer technicians cant figure it out either. The fax server wont send a fax or answer an inbound fax call. We have configured it as MGCP and the fax server is setup in call manager as an H.323 gateway. Any assistance would be greatly apreciated.
