    HONG KONG--(BUSINESS WIRE)--May 12, 2005--Powered by WiseSpot and RADVISION's first commercial 3G UMTS video conference solution, 3 Hong Kong has launched the world's first 3G user-self-enabled video conference service, which allows up to four 3's customers to participate in a video conference anytime and from different parts of the world. This service adopts RADVISION's SCOPIA(TM) advanced video services platform combined with WiseSpot's WiseVSAA video service application architecture.
    WiseSpot, a leading provider of advanced telecommunication value-added solutions in Greater China, and RADVISION, a global provider of multimedia communication and conferencing technologies, have combined their experience and expertise to bring a new dimension to multiparty communication to Hong Kong: that of visual interaction for up to four 3G users at any one session.

With this break-through solution, 3 Hong Kong can deliver enhanced video communication experience to their customers.

By partnering with WiseSpot and RADVISION, we are pleased to introduce the world's first 3G user-self-enabled video conference service. This technological breakthrough brings much convenience and flexibility by allowing customers to engage multiple parties in a single video call to have business meetings, as well as get-togethers for family and friends."
    Franky Lai, Chairman of WiseSpot (Hong Kong) Ltd., said: "With 3G, communication is no longer confined to voice or static visual elements. WiseSpot is a forerunner in the development of video solutions that translate the latest technology into user-friendly services. This video conferencing application demonstrates how, when combined with professional application development and implementation, the power of RADVISION's cutting-edge communication technology can be unleashed to make people's lives easier and more fulfilling."
    "RADVISION is happy that Hutchison chose SCOPIA as the core video services platform upon which they are providing their video conferencing service. RADVISION believes that the future of 3G is in providing innovative and revenue-generating visual services. By teaming with WiseSpot as our local partner, and using RADVISION experience and professional services capabilities, we are confident that additional and exciting applications will be available to 3G users", said Mr. Eitan Livne, General Manager of RADVISION in Asia Pacific.
