The Dialogic 4000 Media Gateway Series (DMG4000 Gateways) is a set of integrated systems designed to connect Microsoft Office Communications Server 2007 R2 to existing PBX systems and PSTN networks. Based on a standard rack-mount server running the Windows Server 2008 x 64 operating system, the Dialogic 4000 Media Gateways are basic hybrid media gateways which are designed, and certified, for the Microsoft Office Communications Server 2007 R2 and therefore include the role of Mediation Server, which is Microsoft's technology providing PSTN and PBX interoperability, high-fidelity VoIP, and security.
The Dialogic 4000 Media Gateways have a familiar user interface, which minimizes Total Cost of Ownership (TCO) by reducing the need for operational and administrative training and special maintenance. In addition, the DMG4000 Gateways keep the number of devices needed to support Office Communications Server 2007 R2 to a minimum by integrating the Mediation Server into a gateway, reducing hardware maintenance.
