AudioCodes' Mediant 3000 and Mediant 1000 Enterprise Session
   Border Controllers Are the First Products in the Market to be
      Certified With Microsoft Lync Server 2010 and Microsoft
   Office Communications Server 2007 R2 for Secured SIP Trunking
                Connectivity Into Verizon Business

LOD, Israel, Nov. 18, 2010 (GLOBE NEWSWIRE) -- AudioCodes
(Nasdaq:AUDC), a leading provider of Voice over IP (VoIP) technologies
and Voice Network products, today announced it has achieved
interoperability qualification for its Mediant 3000 and Mediant 1000
Enterprise Session Border Controllers with Microsoft Lync Server 2010
and Microsoft Office Communications Server R2, when used in conjunction
with Verizon Business' SIP Trunking service. The qualification testing
was conducted by tekVizion Labs, Microsoft's Unified Communication Open
Interoperability Program (UC OIP) testing partner.

By using the AudioCodes' Enterprise Session Border Controllers (E-SBC),
enterprise customers can securely connect their Microsoft Unified
Communications environment to Verizon Business' SIP trunking services,
as well as to other SIP trunking service providers worldwide. The
tekVizion certification confirms interoperability and feature
transparency between the Microsoft system and the SIP trunking service.
With AudioCodes Mediant platforms, customers can support PSTN and SIP
Trunk interfaces in the same box, preventing forklift upgrades, and
enabling gradual migration from costly PSTN circuits to SIP Trunking
services, providing security and interoperability.

AudioCodes' Mediant 1000 platform is a flexible networking device,
supporting a number of services for the Microsoft UC environment. The
Mediant 1000 can simultaneously connect the Microsoft Lync 2010 server,
Microsoft Office Communications Server 2007 or Microsoft Exchange
Server 2007/2010 into existing TDM PBXs, IP-PBXs or PSTN services, as
well as into SIP Trunking services. In addition, it can be configured
as a standalone "Basic" or "Enhanced" gateway, as well as a "Basic
Hybrid Gateway" or "Survivable Branch Appliance", integrating Microsoft
software inside. It can be ordered as a TDM-to-IP gateway, a
Multi-Service Business Gateway, an Enterprise Session Border
Controller, or a combination of the three, supporting up to 120
TDM-to-IP channels and 150 SBC sessions.

AudioCodes' Mediant 3000 platform is an enterprise-class, high density,
fault tolerant Media Gateway and Session Border Controller. It supports
redundant configurations of up to 2016 TDM-to-IP and 1000 SBC sessions,
enabling TDM and IP connectivity for large enterprise' Microsoft UC
environments.

"We are happy to announce another milestone in our roadmap to enable
ubiquitous connectivity for Microsoft UC networks," stated Nimrod
Borovsky, Vice President of Marketing at AudioCodes. "Our Mediant
family of VoIP platforms has been key to our success in delivering
secure and interoperable connectivity solutions for the Microsoft
environment. Enterprises can safely use our products to create a fully
connected Microsoft world, supporting the evolution from TDM PBXs and
PSTN networks, to IP systems and SIP Trunking services."
