Unified Communication

Unified Communication  is the integration of Real-time Communication Services such as Instant Messaging (Chat), Presence Information, Telephony (including IP telephony), Video Conferencing, and Data Sharing with non-real-time communication services such as Unified messaging (Integrated Voice mail, E-mail, SMS and Fax). UC is not a single product, but a set of products that provides a consistent Unified User Interface and User Experience across multiple devices and media types.
