Press Release Body = Dialogic Debuts Hybrid Media Gateways for Unified Communications

Integrated system serves as VoIP gateway and mediation server in compact footprint

VoiceCon, San Francisco. August 21, 2007- Dialogic Corporation ("Dialogic"), a
global provider of world class products and technologies for media and signal
processing, announced the imminent availability of a new breed of media gateways for
unified communications today at the VoiceCon conference in San Francisco,
California.

The Dialogic® 4000 Media Gateway Series (aka "DMG4000 gateways") are 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 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. This unique 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.

Since the Fall of 2006, Dialogic, a Gold Certified member of the Microsoft Partner
Program, has been actively involved in supplying pre-production versions of its new
hybrid gateways to leading enterprise customers and channel partners worldwide for
early adoption testing and pilot installations. There has been significant interest
and early channel partner engagements have yielded positive feedback.

"We worked closely with Dialogic and Microsoft through the development and release
of Microsoft Exchange Server 2007 Unified Messaging last year, and currently with
Office Communications Server 2007," states Tim Bakke, Product Manager for Avtex,
Inc. "As a leading provider of end-to-end business communications solutions, we see
the arrival of the hybrid media gateway as a means of simplifying and reducing the
cost to deploy Microsoft unified communications platform for enterprise customers.
We've worked with Dialogic® products for years, and not only are their gateways easy
to use and reliable, but the level of support offered by the Dialogic team is
unparalleled. Having tested the combined Dialogic and Microsoft unified
communications solution during the beta phase, we anticipate great results for our
enterprise customers."

The DMG4000 Series feature the field-proven and reliable Dialogic® Diva® Media
Boards, Dialogic® Diva® SIPcontrolT 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 high performance 64-bit Dual-Core Intel®
Xeon® 5100 series processors, RAID 1 hard disk subsystem and redundant power
supplies, in a very compact 1U rugged design that can be deployed in a data center
rack. Planned enhancements and features from Dialogic are poised to be easily
installed on these standards based systems. 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.

"Dialogic is excited to be at the center of the unified communications revolution
that the telecom industry and business world is vigorously embracing," states James
Besley, Senior Vice President of Sales and Support for Dialogic. "We have put in
place programs to make it easy for our channel partners and end customers to start
offering and using our media gateways with the Microsoft unified communication
platform. The DMG4000 Series will be a great compliment to our existing media
gateway portfolio - unique in the market, and backed by the best training and
support programs in the industry."

Dialogic authorized distributors began taking advance orders for the DMG 4000
gateways from Microsoft channel partners eager to get familiar with the hybrid
technology on July 16, 2007. The DMG4000 gateway products are scheduled to begin
shipping in September 2007. For more information on these product introductions, or
