PROBLEM TO BE SOLVED: To provide a nurse call system that uses a SIP server for communication, and has an information accumulation function to store an incoming call history, voice, and video. SOLUTION: The nurse call system includes a nurse call slave unit, a nurse call master unit, and a portable nurse call master unit. A patient in a sickroom uses the nurse call slave unit for call and speech. The nurse call master unit and the portable nurse call master unit display a call from the nurse call slave unit and respond to the call. The nurse call master unit and the portable nurse call master unit are mutually connected by a SIP server connecting extensions. The SIP server includes storage units such as a hard disk and an SSD. Each storage device stores a call signal and a caller of the nurse call slave unit, and displays them as an incoming call history. COPYRIGHT: (C)2011,JPO&INPIT
