CallWave Launches ISP Reseller Program for Its VoIP Software Application; Value-added Application Helps ISPs Retain Customers and Earn Incremental Revenue

Business Wire, May 10, 2005

SANTA BARBARA, Calif. -- CallWave, Inc. (Nasdaq:CALL), a leading provider of VoIP enhanced services, today announced the launch of its ISP Reseller Program. Under the program, dial-up and broadband ISPs can profitably resell CallWave's VoIP-based call management application designed for consumers and small businesses.

Unlike VoIP services that require subscribers to replace their existing phone service, CallWave's software-based VoIP application allows users to get more out of their existing landline, wireless and Internet services without purchasing additional hardware. With CallWave, both dial-up and broadband ISP customers can receive important phone calls they otherwise would have missed, screen messages in real time and instantly transfer incoming calls to the most convenient phone. CallWave users immediately know whether they're receiving an emergency call from a family member, an important business call, or a telemarketer solicitation -- giving them the power to decide to take the call.

"CallWave gives ISPs a VoIP-based offering that provides immediate and compelling value for subscribers -- and it's simple to use," said Josh Fraser, Vice President of Business Development for CallWave. "ISPs can easily offer their customers enhanced call management through CallWave's existing VoIP softswitch platform. Our ISP partners improve customer retention, strengthen their brand, and increase average revenue per user by reselling CallWave software."

Steve Mossbrook, President of Wyoming.com, a Midwest ISP, adds, "Our subscribers are able to take advantage of highly valuable services like Internet call waiting and real-time call screening and transfer through co-branded CallWave software. These new services help us to differentiate ourselves from other ISPs -- enabling us to attract new customers and retain existing subscribers."

Charter members of CallWave's ISP Reseller Program include: Wyoming.com, AT&T WorldNet, CoreComm - Voyager, Fidelity Communications, Alacrity.com, DixieConnect, GoBigWest, GoGreatLakes, OhioHills, OneWest.net, SISNA, STIC.net, and Slic.com.

ISPs interested in CallWave's ISP Reseller Program should contact Josh Fraser, Vice President of Business Development, at josh.fraser@callwave.com or 805-690-4139.
