Dialogic DMG 4000

The Dialogic DMG 4000 is a set of integrated systems designed to connect Microsoft Office Communications Server 2007 to existing PBX systems and PSTN networks. Based on a standard rack-mount server running the Windows Server 2003 R2 operating system, the Dialogic 4000 Media Gateways are basic hybrid media gateways designed for the Office Communications Server 2007 and therefore include the role of Mediation Server, which is Microsoft's technology providing PSTN and PBX interoperability, high-fidelity VoIP, and security.
