Dialogic 4000 Media Gateway DDMG4008BRI

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 x64 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.

The Dialogic® 4000 Media Gateways contain field-proven Dialogic® Diva® boards and Dialogic® Diva® SIPcontrol™ Software in addition to Mediation Server software. These elements are integrated in a rugged, compact 1U Intel IP Network Server NSW1U, which features a high-performance 64-bit Dual-Core Intel Xeon processor 5100 series, resulting in a system that can be installed easily in a standard data center rack. The Dialogic® 4000 Media Gateways also offer dual Gigabit Ethernet interfaces for IP network connection. They can be configured to support up to 120 channels of unified communications traffic between legacy networks and an IP network hosting Office Communications Server 2007 R2
