Dialogic 4000 Media Gateway Series
®
The Dialogic
®
4000 Media Gateway Series (DMG4000
Gateways) is a set of integrated systems designed to connect
unified communications solutions to existing PBX systems
and PSTN networks. Based on a standard rack-mount server
running the Windows Server 2008 x64 operating system,
®
the DMG4000 Gateways are basic hybrid media gateways
designed for Microsoft Office Communications Server 2007
®
Release 2 (R2) and therefore include the role of Mediation
Server, which is Microsoft’s technology providing PSTN and
PBX interoperability, high-fidelity VoIP, and security.
Features
Benefits
Large Logo

subsystem, and a failover and load balancing Ethernet
network connection
Provides high availability
Supports supplementary services on ETSI-DSS1, QSIG, and
other TDM protocols
Brings important supplementary services, such as call
transfer, call hold, MWI, and call party information, to an IP
environment

The DMG4000 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 DMG4000 Gateways contain field-proven Dialogic Diva Media Boards and Dialogic Diva SIPcontrol Software in addition
®
®
®
®
™
to the Mediation Server software. These elements are integrated in a rugged, compact 1U rack-mount server featuring a high
performance 64-bit Intel Xeon processor. The DMG4000 Gateways also offer dual Gigabit Ethernet interfaces for IP network
connection, as well as various interface options to the PSTN or PBX, including Analog, ISDN BRI, and E1/T1 interfaces. 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.
Fax Functionality and Third-Party Application Hosting
In addition to the role of hybrid media gateway for Office Communications Server 2007 R2, a DMG4000 Gateway can be used as
a high-density Fax over IP (FoIP) gateway, providing up to 120 channels of fax at V.34 (33.6 kbps) speed.
A DMG4000 Gateway is also capable of hosting third-party Windows Server 2008 based applications, including fax server and
IP-PBX software. A runtime version of the ESTOS Call Control Gateway (ECCG) is pre-loaded on each DMG4000 Gateway with
five complimentary seat licenses for trial purposes. When hosted on a DMG4000 Gateway, this third-party application can provide
remote call control functionality for existing PBX infrastructure (classic, hybrid, or pure VoIP).
The ECCG is middleware for Windows , which enables Office Communications Server 2007 R2 to control an existing PBX and PBX
®
desk phone. The Microsoft Office Communicator Client can initiate PBX desk phone activities, allowing Office Communications
®
Server 2007 R2 to capture presence information for a legacy PBX desk phone and share it across an enterprise and with
federated partners.
