Unified communications is an evolving set of technologies that automates and unifies human and device communications in a common context and experience. It optimizes business processes and enhances human communications by reducing latency, managing flows, and eliminating device and media dependencies.
Unified communications (UC) is the integration of real-time communication services such as Instant Messaging (Chat), Presence information, Telephony (including IP Telephony), Video Conferencing, Data sharing (including web connected electronic whiteboards or Interactive White Boards), Call Control and Speech recognition with non-real-time communication services such as Unified Messaging (integrated Voicemail, e-mail, SMS and Fax). UC is not necessarily a single product, but a set of products that provides a consistent unified user interface and user experience across multiple devices and media types.
