LOD, Israel, March 16, 2010 (GLOBE NEWSWIRE) -- AudioCodes
(Nasdaq:AUDC), a leading provider of Voice over IP (VoIP) technologies
and Voice Network products and a Microsoft Gold Certified Partner, is
extending its product range for customers seeking access to the
Microsoft Unified Communications environment with the introduction of
AudioCodes' SIP Phone Support (SPS) for Microsoft Unified
Communications. AudioCodes' SPS allows economically affordable
connections to Microsoft Office Communications Server via standard SIP
IP Phones. A direct connection to Office Communications Server is
supported both for currently installed phones and newer models, as well
as connecting mobile phones using AudioCodes' Mobile Clients, utilizing
AudioCodes' gateway technology.

"Office Communications Server 2007 R2 has been a game changer for our
customers, providing enhanced communications, significant ROI, and
short time frames for payback. The ease by which any telecommunications
environment can be UC-enabled with Office Communications Server 2007 is
truly unique in the industry," said Hugh Oakes, Managing Director
Time2Market. "Now with AudioCodes' SPS, it's even easier and more
cost-effective to migrate to Office Communications Server 2007 R2. The
requirement of changing out your legacy handsets is mitigated, we can
leverage the SIP handsets already in place. The ability to use the
existing handsets makes the migration to Unified Communications even
more cost-effective and provides yet another reason why we always
recommend that our customers deploy Office Communications Server with
AudioCodes' gateways." Time2Market is a Microsoft Gold Certified
partner with the coveted voice specialization.

Enterprises migrating into the Microsoft Unified Communications
environment have been showing great interest in enabling cost-effective
IP Phones to connect to Office Communications Server. According to
Synergy Research, the current installed base of IP Phones in the market
is approximately 65 million. By 2014, around 20 million new IP Phones
will be sold annually. Most of these phones have not had direct access
to Microsoft Office Communications Server. Gartner Magic Quadrant for
Unified Communications 2009 stated that "Enterprises looking into UC,
particularly those with Microsoft applications already in place, should
understand the Microsoft portfolio, because it represents a new
paradigm for communication by a market leader. Microsoft's solution,
while comprehensive, is also the basis for a range of partner
offerings." Based on the Microsoft leadership and customers' demand for
partner solutions, customers can now protect their existing investment
in third-party IP-Phones, while enjoying the full benefits of the
Microsoft infrastructure, including unified call control, integration
with their Microsoft Office Communicator, presence information and
more.

"We believe that this is a very significant announcement since many
enterprises are dependent on Microsoft desktop applications and have
been forced to live in two separate worlds, one for their phone
technology and the other for their desktop software environment," said
Elka Popova, North American Program Director, Unified Communications &
Collaboration, Frost & Sullivan. "Many enterprises are looking for
integrating the two worlds by connecting their existing installed base
of IP Phones directly to the Microsoft Unified Communications
environment."

The IP phones supported by SPS include AudioCodes' 300HD family of High
Definition IP Phones, as well as other third-party IP Phones, such as
Cisco, Avaya, Aastra, Polycom and other standards-based SIP phones. The
mobile smart phones support is enabled using AudioCodes' Mobile SIP
clients, supporting all major smart phones' operating systems,
including Windows Mobile, iPhone OS, Symbian and Android.

AudioCodes' 300HD family of IP Phones offer integrated, DSP-based
support of Microsoft Real Time Audio (RTA) codec and the support of
Secured Real Time Protocol (STRP) and SIP over TLS, enabling maximum
security, high definition calls between IP Phones and Office
Communicator clients. In addition, AudioCodes' phones provide enhanced
presence and Active Directory support in the phone user interface,
offering enhanced user experience for the Microsoft clients.

"Utilizing AudioCodes' Mediant family of Media Gateways, SPS can enable
connectivity of other vendors' SIP phones into the Microsoft
environment," stated Lior Aldema, Chief Operating Officer at
AudioCodes. "Supporting Secure RTP and enabling a wide variety of
narrowband and wideband codecs, AudioCodes' SPS can connect legacy SIP
phones into the Microsoft Office Communications Server environment,
while maintaining security, providing high quality voice and user
presence."

Existing customers of AudioCodes' Mediant gateways can now upgrade
their existing installed base to support SPS. The same gateway can
support the SPS functionality while providing a Media Gateway function
between Microsoft Office Communications Server and/or Microsoft
Exchange Server and the enterprise TDM PBX and/or the PSTN. SPS can
scale from small demos of a few users all the way up to supporting
enterprise installations of thousands of IP Phones and SIP Mobile
Clients. By optionally integrating it with the different AudioCodes'
Mediant Media Gateways it can scale from 120 concurrent RTP to SRTP
calls on the Mediant 1000 all the way up to 884 calls on the
fault-tolerant Mediant 3000.
