Unified communications (UC) is the integration of real-time communication services such as instant messaging (chat), presence information, telephony (including IP telephony), video conferencing, 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 a single product, but a set of products that provides a consistent unified user interface and user experience across multiple devices and media types.UC also refers to a trend to offer Business process integration, i.e. to simplify and integrate all forms of communications in view to optimize business processes and reduce the response time, manage flows, and eliminate device and media dependencies.UC allows an individual to send a message on one medium and receive the same communication on another medium. For example, one can receive a voicemail message and choose to access it through e-mail or a cell phone. If the sender is online according to the presence information and currently accepts calls, the response can be sent immediately through text chat or video call. Otherwise, it may be sent as a non real-time message that can be accessed through a variety of media. Unified Communications DefinitionAn evolving communications technology architecture which automates and unifies all forms of human and device communications in context, and with a common experience. Its purpose is to optimize business processes and enhance human communications by reducing latency, managing flows, and eliminating device and media dependencies. Communication LatencyOne of the main focuses of unified communications is to reduce communication response time, or in other words perceived speed, which often is essential in decision making and acting upon instructions. For example, an important action that takes two days to complete but is received a day late, takes three days to complete. Unified communications technology aims to minimize that del...
