Centra Summit 2004 is Centra's Fifth Annual Worldwide User Conference, set for May 11th to the 14th, at the Westin Copley Place Hotel in Boston, Massachusetts. Head Coach Bill Belichick of the New England Patriots, football world champions, and Paul R. Gudonis, Centra's President and CEO, will deliver the keynote addresses, kicking off the four-day event themed "Driving Value Through Collaboration."

Centra Summit 2004 is the largest vendor-hosted event in the online business collaboration industry and is expected to draw a record number of attendees from around the globe. Attendees can expect Centra Summit to deliver on a tradition of excellence with comprehensive, high-quality programs that include speakers from leading organizations, hands-on labs, a solutions demo center, and more than 60 customer- and partner-led workshops. Attendees will also benefit from a host of networking opportunities and festivities, highlighted by an evening at the Fogg Art Museum, Harvard's oldest art museum.

"On behalf of Centra and our entire user community, we want to thank Andrea for their sponsorship participation in this year's Centra Summit, where our conference attendees will have a great opportunity to learn more about this world-class organization and their technology," said Joseph Gruttadauria, Senior Vice President, Professional Services of Centra Software. "A long-term partnering commitment from companies like Andrea fuels our growth and success. Because of their contribution, we are all looking forward to an exciting, information-packed week at Centra Summit 2004."

As the premier sponsor, Centra Summit attendees will be directed to visit Andrea's booth where they will receive the newly introduced Andrea NC-95 Anti-Noise Headset. Additionally, Andrea will conduct a workshop during the Summit titled "Best Real Time Collaboration Audio Input/Output Practices." The goals of this workshop are to educate conference attendees on the importance of quality desktop audio input/output devices, to discuss microphone technologies applicable to various working environments and to demonstrate Andrea's portfolio of complementary audio hardware and software products.
