FRAMINGHAM, MA, Feb. 13, 2006–NMS Communications (NASDAQ: NMSS), a leading provider of technologies and solutions for mobile applications and infrastructure, today announced it has signed a definitive agreement to acquire Openera Technologies, a leading provider of mobile application handset solutions for converged mobile networks. Openera will become an integral part of NMS’s Mobile Applications business, reporting to Mark Grindeland, vice president and general manager

Openera’s Mobile IMS Client serves as a single, simplified pathway for launching and managing Openera’s portfolio of presence-based applications, including Peer-to-Peer Video Sharing, Active Phone Book for community services, Push to Talk over Cellular and Instant Messaging. Openera’s SIP-based solutions enable the rapid delivery of these emerging IP multimedia communication services on mobile devices spanning 2.5G, 3G, IMS and WiFi networks.

We are very excited about the strategic value of this acquisition, which brings us important new applications, product expertise and customer relationships”

The acquisition positions NMS as a leading mobile service enabler, delivering personalized, content-rich, user-centric applications and services. Openera’s integrated portfolio of client-based 3G and IMS mobile applications for smart-phone and feature-phone platforms complements NMS’s network-based applications and technology, enabling the company to deliver exciting new services to existing and new customers. The combined capabilities will provide mobile operators and next-generation service providers with an end-to-end solution – incorporating network integration, applications, content and an optimal user experience – targeted specifically at 3G wireless, IMS, and mobile Internet applications and services.

“We are very excited about the strategic value of this acquisition, which brings us important new applications, product expertise and customer relationships,” said Bob Schechter, NMS Communications’ chairman and CEO. “Through our MyCaller(TM) offering, NMS Communications has gained a substantial market footprint as a leading provider of ringback tones and personalized caller entertainment services. Leveraging that experience and this acquisition, we’ll bring to market a complete set of end-to-end application solutions that incorporate subscriber ease of use and personalization, content search and discovery, and that set the stage for highly targeted and effective content marketing. These solutions will help operators and next-generation service providers realize the full potential of their network investments and customer relationships in today’s mobile communications services market and the rapidly emerging mobile Internet.”

“At Openera, we recognize the benefits of providing an end-to-end solution with a long-established industry leader like NMS,” said Joel Hughes, Openera CEO. “With the resulting ability to deliver community-based mobile applications, multimedia personal communications, licensed and user-generated content applications and complete mobile marketing solutions, NMS will be uniquely positioned to provide mobile operators with the next generation of high-value applications and technology that have the greatest impact on their business.”

“The merger represents a strong validation of Openera’s market and technology leadership and of our core belief that world-class technology products can be conceptualized, designed and developed in India,” said Jawad Ayaz, Openera founder and CTO. “We firmly believe that the unique strengths of the individual businesses will come together to create an entity that will be a market leader in the wireless applications space.”

NMS will maintain Openera’s operations in Bangalore, India, and Hughes and Ayaz will play critical roles at NMS in the ongoing development of the company’s Mobile Applications business.

Completion of the transaction is expected to occur within the next few weeks, for consideration of $16.4 million in stock, approximately 51 percent of which is contingent upon the continued employment of key employees of Openera over the 30-month period following the closing. The company anticipates the financial effect of the transaction to be neutral to its 2006 earnings, before taking into account the effect of amortization of the non-cash compensation and other purchased intangibles. The effect of these non-cash amortization charges will be determined based on an asset valuation analysis yet to be completed and will have a significant effect on the company’s GAAP earnings.
