Xten software on Symbol handheld computers provides a mobile voice solution that enables next generation connectivity and collaboration across Symbol's voice capable Windows Mobile platforms. The first product supported is the MC50 Enterprise Digital Assistant (EDA). Generating an overwhelming positive response, Xten demonstrated the handheld SIP softphones with the Symbol MC50 EDA at the Voice on the Net show in March of this year. "Wireless IP communications is the future and our Pocket PC softphone is an important component in our wireless strategy," commented Erik Lagerway, COO and President for Xten. "Symbol has a long standing reputation for producing top quality Pocket PC devices for the Enterprise. We are excited to take this first step in working with Symbol, and see this as an excellent opportunity for Xten to increase visibility for our handheld wireless VoIP software in vertical markets, such as retail, where Symbol is a recognized worldwide leader." "Symbol's MC50 is designed for mobile professionals seeking to capture, move and manage information at the point of business activity in order to increase productivity and efficiency, while improving customer responsiveness and satisfaction," said Chuck Dourlet, vice president of Mobile Computing, Symbol Technologies. "With Xten's validated voice solution, the MC50 can become an even more powerful and versatile tool for our customers - enabling on-the-spot decision making with real time access to people and information." Introduced in October 2004, the MC50 is the first in a new family of EDA products specifically designed for business-essential applications within the enterprise environment with a particular focus on durability, manageability and lifecycle management. Featuring industry-standard-based and additional Symbol wireless security capabilities, the MC50 also includes integrated voice capability with a designed-for-voice electrical and mechanical design. With the MC50, VoIP solutions can be deployed enabling in-building and on-campus communications for real-time responses and improved customer satisfaction. Xten's softphones for Windows, MAC OS X and Pocket PC are software applications, which run on devices such as personal computers (PCs) or personal digital assistants (PDAs) or can be integrated into web pages or web applications. 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 their IP handset at a fraction of the cost, while providing more features and functionality than the IP handset.
