(OTCBB: XNWK), a provider of VoIP (Voice over Internet Protocol), Video over IP, Instant Messaging (IM), and Presence SIP softphones, today announced that Technology Marketing Corporation (TMC(R))'s Communications Solutions magazine online (http://www.tmcnet.com/comsol) has named Xten's eyeBeam Software Development Kit (SDK) as a recipient of a 2004 Product of the Year Award. "We are very pleased to be recognized by an industry leading publication for the innovation that goes into our products," said Erik Lagerway, COO and President of Xten. "We aim to continue this award-winning pace with the release of eyeBeam 2.0 SDK due to be released sometime this year." Xten's softphones for Windows, MAC OS X, Pocket PC and now Linux are software applications, which run on devices such as personal computers (PCs) or personal digital assistants (PDAs) or can be integrated into set-top boxes, embedded devices, instant messenger applications and alike. When an Xten softphone is connected to a service provider's network, the user can make and receive calls to and from other "on-net" callers (IP-to-IP) and/or "off-net" callers (IP-to-PSTN/Cellular) with the same quality of service they would expect from an IP handset. However, at a fraction of the cost, while providing more features and functionality than an IP handset. "Each year Communications Solutions magazine bestows its Product of the Year awards on companies that have demonstrated excellence in technological advancement and application refinements. Xten Networks has demonstrated to the editors of Communications Solutions that its products or services have gone the extra mile to help improve both the customer experience and the ROI for the companies that use them," said Rich Tehrani, President and Group Publisher of Communications Solutions.
