SPEAKER NOTES: VoIP is a path to UC.
A general definition of Unified Communications is: Unified Communications is when multiple communications tools come together in a way that brings much more value to the end user than any of the communication tools stand alone.
AT&T’s definition of Unified Communications and Collaboration is the integration of multiple communication & collaboration tools with presence, behind a single user interface, accessible from wired and wireless devices, and is designed to deliver real business benefits to customers.
UC gives you a single control point to access multiple applications utilized independently today - with the device you want to access it through.
Unified Communications offers businesses the ability to significantly improve how individuals, groups and companies interact and perform.
Collaboration has become mission-critical for enterprises seeking to create agile, effective organizations.  Imagine connecting employees, partners and vendors in a manner that suits them wherever they are, over any device - wired or wireless, PDA or personal computer. 
Presence
Mobility
Desktop
Unified Communications Integrates multiple communication tools with presence, behind a single user interface that is accessible from almost any device from virtually anywhere
