FOR IMMEDIATE RELEASE: Tokyo, Japan — February 4, 2004 — INTERNATIONAL SYSTEMS RESEARCH CO. (ISR) announced today that the development of PPPhone , the mobile IP telephone system, has been successfully completed, marking its entry into the IP Telephony solutions business. ISR will offer PPPhone, the mobile IP phone service, in partnership with major IP telephony carriers and ISPs. PPPhone may be used with mobile devices like Notebooks and PDAs, and may be combined with network solutions such as IP Centrex and IP-VPN. PPPhone transforms the IP Phone terminal into a ubiquitous phone extension (inside or outside the office) and provides the capability of making calls to external lines as well as receiving calls. A key feature of PPPhone is ISRs proprietary PPPush function (patent pending) which allows a mobile device equipped with @FreeD flat-rate PHS card to receive inbound calls even if it is turned off. The PDA is automatically awaken from power-off/-saving mode by WakeOnRing (*1). As compared to existing cellular phone services, PPPhone can: 1) Allow a PDA to be used as an internal telephone (extension line) away from offices free of charge. The conversation of PPPhone Softphone -to- PPPhone Softphone or PPPhone Softphone -to- subscribed IP phone becomes a conversation between extension telephones. 2) Allow users to make calls directly to an extension number outside the office thanks to the connectivity with the IP Phone providers' network solutions such as IP centrex and IP-VPN.
