Unified Communications (UC) is the integration of real-time communication services such as instant messaging (chat), presence information, 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 on another. It should be possible to easily transfer any activity or message to another medium. For example, one can receive a voice mail message and choose to access it through email 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.
