Scenario: 3CX Phone System and PCI Modem are on same server. Specs: Windows Server 2003 R2 3CX Phone System 6 Lucent V.90 Data/Fax/Voice Modem (PCI) Issue: I cannot find and option to connect 3CX Phone System with PCI modem. All apps show incoming signal (i.e. Windows Fax, CallderID, etc.) and works fine, but not 3CX. Any ideas?
