Dialogic Debuts Hybrid Media Gateways for Unified Communications

Dialogic introduced its DMG4000 Media Gateway series designed to connect Microsoft Office Communications Server 2007 to existing PBX systems and the PSTN.


Based on a standard rack-mount server running Microsoft Windows Server 2003, the DMG4000 gateways are in the class of "basic-hybrid gateways" designed to provide both the media gateway function and the Mediation Server role of Office Communications Server 2007.



Mediation Server provides PSTN and PBX interoperability, high-fidelity audio via the Microsoft RT Audio Codec, and VoIP security for Office Communications Server 2007.



Dialogic said its integration of a media gateway subsystem and Windows Server 2003 delivers two key elements of an Office Communications Server 2007 deployment in one easily managed, 1U rack mount device. The Mediation Server software from Microsoft is a required element of an Office Communications Server 2007 deployment with PBX or PSTN integration, and will come pre-installed on the Dialogic 4000 Media Gateway Series.



The DMG4000 Series feature the Dialogic Diva Media Boards, Dialogic Diva "SIPcontrol" software, Windows Server 2003 and the Mediation Server software for Office Communications Server 2007. These elements are integrated in an Intel IP-Network Server featuring 64-bit Dual-Core Intel Xeon 5100 series processors, RAID 1 hard disk subsystem and redundant power supplies, in a 1U rugged design that can be deployed in a data center rack.



The media gateway sub-system offers dual load-balancing Gigabit Ethernet interfaces towards the IP networks, as well as a choice of either two or four T1/E1 interfaces towards the PSTN or PBX. The two integrated turnkey configurations can support up to 60 or 120 channels of unified communications traffic between legacy networks and the IP network and thus are capable of supporting hundreds of IP endpoints registered to Office Communications Server 2007. Multiple units can be co-located or distributed across a managed IP network as enterprises scale up their unified communications deployments.
