CallWave First to Market With Enterprise Unified Communications Solution for Apple iPhone

CallWave, Inc. (NASDAQ:CALL), a leading global provider of mobile and Web-based unified communications solutions, today announced the first true enterprise unified communications solution for the Apple iPhone. The new version of CallWave's award-winning WebMessenger Mobile extends Microsoft's industry-leading unified communications platform, Office Communications Server (OCS), to iPhone-carrying mobile workers. WebMessenger Mobile for the Apple iPhone can be downloaded by users from the Apple App Store, and is being demonstrated this week in the CallWave booth, number 1112, at Interop New York.

Microsoft OCS manages all real-time (synchronous) communications including instant messaging, VoIP, audio and video conferencing. Microsoft OCS also powers presence, a key benefit of Microsoft unified communications that unites all the contact information stored in Active Directory with the ways people communicate. WebMessenger Mobile extends similar functionality to the iPhone, enabling business professionals to achieve the same collaboration and productivity benefits in the field that they experience in the office. WebMessenger Mobile was the recipient of the best enterprise application award in the 2008 AT&T Fast-Pitch competition at a recent mobile industry event.

"Users want more choice, and enterprises want to give them greater communication capabilities by extending their communications infrastructure to their iPhones," said Joe Naylor, senior vice president of sales, CallWave. "Companies are investing in Microsoft OCS and need to support mobile workers using iPhones. WebMessenger Mobile for the Apple iPhone answers the call by helping business professionals work wherever, whenever and however they choose. Again, CallWave is at the forefront of innovation in the mobile unified communications market."

CallWave's WebMessenger federates IM, IP telephony and presence technology across leading platforms, allowing mobile professionals to collaborate seamlessly on any service in a secure environment. In addition to supporting the iPhone, CallWave is the only provider extending Microsoft OCS out to BlackBerry and Nokia smartphones.
