Improves reliability of IP-based unified communications by maintaining connectivity for up to 1,000 users per branch, even if WAN goes down

San Jose, CA -April 4, 2011 - Dialogic Inc. (NASDAQ: DLGC), a leading provider of communications technologies that power advanced networks and a Microsoft Gold OEM / Hardware Partner, has joined the Microsoft Technology Center Alliances Program. The Microsoft Technology Centers (MTCs) are collaborative environments that provide access to innovative technologies and world-class expertise, enabling customers to envision, design, and deploy solutions to meet their exact needs. By joining the MTC Alliances Program, Dialogic is able to help Microsoft demonstrate the unified communications capabilities of Microsoft® LyncTM Server 2010 utilizing the Dialogic® 4000 Media Gateway Survivable Branch Appliances (DMG4000 SBAs).

The DMG4000 SBAs were designed with ease of use, ease of deployment and security as top priorities. When deployed with Lync Server 2010, the solution set improves the reliability of the IP-based unified communications in a branch location by maintaining voice resiliency even if the connection to primary Lync services in remote corporate data centers fails. With a range of models capable of supporting 25 to 1,000 users, the DMG4000 SBAs are well suited for replacing legacy PBX infrastructure in branch locations of many sizes.

"A reliable, easy to deploy Unified Communications solution is essential to enterprise customers to maintain optimum productivity and efficiency," said Chris Kunze, Technology Architect from the Minneapolis MTC. "In other words, corporate communications services can't go down. Now, with Micosoft Lync and the DMG4000 survivable branch appliances, Unified Communications connectivity can be maintained regardless of WAN status."

"The introduction of Lync Server 2010 and the DMG4000 survivable branch appliances allows customers to consolidate communications services in regional data centers and move forward confidently with PBX replacement in the branch, eliminating many legacy voice infrastructure and maintenance costs, while benefiting from the productivity strengths of unifying their communications," said Franz-Josef Eberle, vice president and general manager, Value Added Services and Cloud Enabling Group at Dialogic. "We are pleased to participate in the Microsoft Technology Center Alliance Program to help demonstrate these competitive advantages."
