Unified Communications (UC) is a technology that combines multiple communication methods, such as instant messaging, video conferencing, and voice calling, into one system. It allows users to access and manage communications from a single, unified platform, streamlining communication and collaboration across an organization. UC solutions also offer features such as presence detection, so users can see if someone is available to communicate and select the best way to reach them. With UC, organizations can reduce costs, increase efficiency, and improve customer service.
