Southborough, MA – September 21, 2004 – For the fifth year, Network World is challenging IP PBX vendors to prove their claims at the Voice on the Net (VON) conference and exposition. VON hosts this showdown on Wednesday, October 20 from 2:45 to 4 p.m. where six prominent VoIP vendors, Avaya, Cisco, Lucent, Mitel, Nortel and 3Com, have been invited to present their solution to a hypothetical request-for-information (RFI) from a fictitious company.

The six vendors will be given the opportunity to walk through their proposed architecture and its advantages and then field questions from John Dix, Editor-in-Chief, Network World, and Carl Ford, VP of Community Development, VON.

"We take the time to organize debates and showdowns so that IT professionals have the opportunity to see vendors battle it out on a level playing field," said John Dix. "For years, IT departments have been trying to get these competitive firms at their site at the same time so they can compare apples-to-apples. At this year's VON, we give the vendors the opportunity to prove themselves."

VON is being held at Boston's Hynes Convention Center from October 17 to 21. Last year's conference attracted over 3000 IT professionals interested in IP platforms. Full conference detail is available at
