CommuniGate System's Jon Doyle to Deliver Keynote Address for Ziff Davis Enterprise Virtual Trade Show Focusing on Unified Communications

Doors open at 9 a.m. EDT on October 10 for free, full-day virtual event

Mill Valley, CA - October 8, 2007 - CommuniGate Systems, the leader in scalable carrier-class Rich Media solutions, today announced that Jon Doyle, Vice President of Business Development, will deliver the keynote address for the Ziff Davis Enterprise Unified Communications Virtual Tradeshow on Wednesday, October 10 at 11:00 a.m. EDT/8:00 a.m. PDT. Doyle's presentation will kick off a full day, information-packed virtual event from Ziff Davis Enterprise titled, "Unified Communications- Opportunity Talks: Unified Communications Come of Age."

Doyle's keynote address, "The Business Benefits of Unified Communications," explores how companies can reap enormous benefits from Unified Communications in terms of money, employee productivity, and time. Along with Doyle, Charlene O’Hanlon, Senior Editor at Ziff Davis Enterprise, will moderate the presentation.

"With each new form of communication and rich media technology, we're adding another level of complexity - another platform to manage, and another password to remember. Just take a look at your colleague's business card; there's an office number, a mobile number, e-mail address, IM identity, Skype number, and on and on," said Jon R. Doyle, VP Business Development at CommuniGate Systems. "Unified Communications has the potential to save us from this complexity  multiple media types, one account, and true portability of address. So whether you want to send an e-mail, download a song, set up a videoconference, read the latest RSS feed, or chat with a colleague overseas, you don't need to shuffle identities or switch from one application to another."
