The eyeBeam feature set includes all of the robust SIP telephony features expected from Xten, plus H.263 and H.264 IP video conferencing, CDMA cellular network support and a host of new IP telephony features. The eyeBeam production software and low-level SDK will support wireless CDMA cellular networks, like those offered by Sprint, Verizon and Telus. Wireless Carriers will be able to provide direct calling from eyeBeam SIP softphones to cellular phones, and visa versa, without any transcoding.

Based on our research, eyeBeam is the first SIP softphone in VoIP history to complete bi-directional full duplex voice calls to and from a wireless CDMA cellular phone without the aid of a Media Gateway," explains Erik Lagerway, President and Chief Operating Officer of Xten. "Wireless carriers could realize significant reductions in equipment costs alone, not to mention the flat-rate revenue potential for calling plans which offer calls between Internet-based SIP softphones and wireless cellular phones. Wireless VoIP suddenly has a whole new meaning!" The upcoming Beta release of eyeBeam will only be available to select Xten partners, with the commercial release scheduled for October. Open standards based Instant Messaging and Encryption will be available later in the fall. Xten's softphones are carrier-grade IP telephony SIP endpoints, delivering the quality of service and features large providers require for their customer base. Xten's feature-rich FREE SIP softphone - X-Lite(TM) - does not include some of the advanced features found in our commercial software but still provides superior call quality. Xten's softphones are fully RFC3261 (SIP), RTP/RTCP (RFC 1889) and SDP (RFC 3264) compliant. They are available for Windows (Windows 98SE/ME/NT 4/2000/XP/CE), Mac OS X, Linspire and Pocket PC operating systems.
