Openwave Messaging Suite brings simple, integrated user experience of messaging services including E-mail, Voicemail, text-to-speech and Fax

REDWOOD CITY, Calif. - March 30, 2005 -- Openwave Systems Inc. (Nasdaq: OPWV), the leading provider of open software products and services for the communications industry, today announced that Spanish fixed, broadband and mobile telecommunications operator Auna Group has selected Openwave's voice messaging as its new IP-based next generation voicemail system. Both Auna Tlc and Amena will implement Openwave's unique IP Integrated Messaging infrastructure, based on Openwave's "all-IP" Messaging Mx platform, to deliver converged messaging services to its fixed and mobile customers.

Openwave's Messaging Suite will enable Auna Group to differentiate by converging mobile and broadband messaging experiences, providing its customers with a variety of integrated messaging services including E-mail, Voicemail and text-to-speech functionality. Whether accessed via the web or a mobile WAP interface, Auna customers will be able to manage messages of any type through a single inbox and simple user interface. As such, Openwave's infrastructure will enable Auna to differentiate its service offering with an improved user experience, bringing a degree of flexibility otherwise unavailable in the market today.

To ensure that its messaging customers are protected against spam and virus attacks, Auna will also reinforce its offering with Openwave's Mx-integrated anti spam and anti virus solution. Through the Mx Extensions technology, Auna has the ability to "plug in" value-added and best-of-breed processing software such as anti-virus, anti-spam or lawful mail interceptions (CALEA) efficiently and cost effectively.

"We are extremely excited to be working with Auna to help it deliver a fully integrated messaging experience to its customers and to further extend its leadership within this market by improving their service quality, said Rich Wong, general manager, messaging products group, Openwave. "With years of experience at the forefront of IP messaging, Openwave is delighted to enable Auna to both differentiate its service offering as well as protecting Auna's customers from spam and virus abuse."

As part of the messaging solution, Auna has selected Brooktrout's SnowShore Media Server™, which has been optimized to work with Openwave's messaging suite. The SnowShore Media Server leverages the simplicity and flexibility of SIP and VoiceXML to provide an open, scalable IP media server solution, powering a broad range of voice and video services for next-generation wireline, wireless and broadband networks.

"Brooktrout's expertise in media processing platforms, coupled with Openwave's leadership in multimedia messaging and email software provides an ideal platform for the deployment of standards-based messaging applications," said Peter Vescuso, vice president of Market Development for Brooktrout Technology.
