PROBLEM TO BE SOLVED: To improve user-friendliness for reporting and conforming of paging contents. SOLUTION: When the paging channel selecting function and the speaking function of one of plural interphone master machines 1a, 1b, 1c,...1n are made active, contents of paging are reported from plural speakers 5a, 5m, 5c,...5n for paging through a paging adapter 2 and an amplifier 3 for paging, and they are recorded in a sound storage part 4a included in a paging storage device 4 while the paging channel selecting function is made active. The activated paging channel selecting function is made inactive, time counting of a timer part 4b included in the paging storage device is started, and contents of paging recorded in the sound storage part are erased after a certain time. Contents of paging recorded in the sound storage part are reproduced while the paging storage device channel selecting function of one interphone master machine is made active.
