Lucent Technologies Announces Agreements with Two Companies to Deliver VoIP and IMS-Enabled Services Via Mobile Devices And PCs Openera and Xten Networks' Solutions to be Integrated with Lucent's Industry- Leading IP Multimedia Subsystem (IMS) Convergence Solution MURRAY HILL, N.J., Feb. 14 /PRNewswire-FirstCall/ -- Lucent Technologies (NYSE:LU) today announced it will integrate software solutions from Openera and Xten Networks (OTC:XNWK) (BULLETIN BOARD: XNWK) with Lucent's industry-leading IP Multimedia Subsystem (IMS) convergence solution to support the delivery of voice over IP (VoIP) and new converged "lifestyle" services -- across a variety of wireless and wireline networks -- to mobile phones, personal digital assistants (PDAs) and personal computers (PCs). Both Openera and Xten Networks will provide downloadable clients that can support a wide range of devices and enable the delivery of converged service bundles. Under the agreements, Openera will supply its Mobile IMS Client, which enables the delivery of advanced IMS-based multimedia services including Active Phone Book, push-to-talk and video sharing on mobile phones. Openera's Mobile IMS Client can be rapidly deployed across a range of mobile phone manufacturers' existing handsets and can be customized and re-branded for use within a service provider's network. Xten Networks will supply its X-PRO SIP "softphone" application, which simulates the features and functionality of a small business phone system and enables VoIP services on wireline or wireless broadband connections for PC- based and Pocket PC based devices. Xten Networks' softphones are available for Windows, Mac OS X and Pocket PC operating systems. "Lucent is committed to helping service providers increase customer satisfaction and reduce churn by delivering Value Over IP(TM), VoIP and 'blended-lifestyle' services, and IMS-capable devices are a critical piece of the equation," said John Leonard, vice president of offer management for Lucent's Mobility Solutions Group. "By incorporating these solutions from Openera and Xten Networks into our Accelerate(TM) Next Generation Communications Solutions portfolio, which includes Lucent's IMS solution, service providers will be able to offer their subscribers exciting new services on a plethora of popular devices." The foundation of Lucent's converged networking portfolio is the Lucent IMS solution, a service delivery platform that enables service providers to simply and cost-effectively introduce new VoIP and multimedia services. Lucent's IMS solution enables operators to deliver services that blend voice, video and data capabilities, simplifying the creation of converged "lifestyle" service bundles. It also helps reduce the introduction costs and time-to- market for new services by leveraging a common applications infrastructure to deliver services with a common "look and feel" across third-generation (3G) mobile, WiFi, and wireline networks. Lucent and Openera are demonstrating Lucent's IMS solution and Openera's Mobile IMS in Lucent's hospitality suite (on the Pantiero just outside the Palais des Festivals) at the 3GSM World Congress 2005, taking place from Feb. 14 - 17 in Cannes, France.
