Abstract
PURPOSE:To take a rapid and adequate countermeasure by automatically recording the contents of an emergency information call by utilizing an existing private branch switching function nearly as it is, and by reproducing and monitoring them accordingly. CONSTITUTION:By dialing a special number for emergency information from an optional extension telephone set TEL, a special telephone set SPTEL for reception of emergency information is called. Those telephone sets and a call voice recording and reproducing device VRS are placed in multiparty calling mode to record the contents of an emergency information call automatically. After the emergency information call is terminated, the special telephone set SPTEL is connected to the device VRS in accordance with calling by dialing a special number for emergency information call reproduction, and the contents of the emergency information call recorded are reproduced and transmitted.
