Unified Communications (UC) is a marketing buzzword describing the integration of real-time, enterprise, communication services such as instant messaging (chat), presence information, voice (including IP telephony), mobility features (including extension mobility and single number reach), audio, web & video conferencing, fixed-mobile convergence (FMC), desktop sharing, data sharing (including web connected electronic interactive whiteboards), 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.〔 〕 In its broadest sense, UC can encompass all forms of communications that are exchanged via a network to include other forms of communications such as Internet Protocol Television (IPTV) and digital signage Communications as they become an integrated part of the network communications deployment and may be directed as one-to-one communications or broadcast communications from one to many. 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. ==Definition== There are varying definitions for unified communications.〔(Cloud network architecture and ICT - Unified communication(UC) technologies, integration of telecommunications, computers, middleware and the data systems that support, store and transmit UC communications between systems. )〕 A basic definition is "communications integrated to optimize business processes and increase user productivity," but such integration can take many forms, such as: users simply adjusting their habits, manual integration as defined by procedures and training, integration of communications into off-the-shelf tools such as Thunderbird, Outlook, Lotus Notes, BlackBerry, Salesforce.com, etc., or purpose-specific integration into customized applications in specific operating departments or in vertical markets such as healthcare.〔(UCStrategies on "What is Unified Communications?" )〕 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.〔(Rick McCharles Article on UC )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Unified communications」の詳細全文を読む スポンサード リンク
