Free WEB 2.0 Widgets Are Key Elements of Company's Strategy to Integrate Voice and Text

SANTA BARBARA, Calif. -- CallWave, Inc. (NASDAQ:CALL) today announced the launch of its text messaging widget (also known as a gadget) - a free, desktop-based application enabling users to send text messages worldwide right from their desktop.

"Our SMS text platform maximizes the time consumers spend at their computer and demonstrates CallWave's commitment to simple and innovative uses of the desktop as a companion to the mobile phone," said David Hofstatter, Chief Executive Officer for CallWave. "Text messaging continues to grow in popularity, but many consumers find it difficult to text on a phone's small interface. By making it easier to send text messages worldwide from the desktop, we believe we will dramatically increase text adoption and daily usage. When combined with our voice applications and ability to store all messages in a permanent, searchable archive that is accessible from a personal web page, CallWave can deliver tremendous value to today's highly mobile, internet savvy consumers."

Continued Hofstatter, "WEB 2.0 widgets are an explosive channel for delivering cutting-edge software and services to end-users. They are extremely simple to download and this one creates an innovative new way to send text messages. However, the real opportunity for CallWave is to extend the benefit of these lightweight applications to our carrier partners as a way to extend their brand to the desktop, increase daily use and create the ultimate retention solution."

The CallWave Free Text Messaging Google Gadget

For mobile phone users who also use the web each day, the CallWave Free Text Messaging gadget (also known as a widget) delivers invaluable ease and efficiency - making the PC a natural companion to the mobile phone. It allows users to send text messages to virtually anyone, anywhere, right from their desktop - whether their handset is nearby or not. During the beta, subscribers can send unlimited text messages from the United States and Canada.

The Google Desktop enables consumers to create their own personal homepage on Google. Gadgets can be added from the "add stuff" link. The CallWave Free Text Messaging gadget can be found in the "Communication" section or by simply typing in "CallWave" in the search field. With the gadget running on the Google Desktop, users can view a list of contacts and select who to text. Replies to the message can be routed to either the subscriber's handset or email, depending on their personal settings. Subscribers will eventually be given access to their messages stored in a permanent, searchable archive, accessible from a personal web page.
