Abstract

PURPOSE:To prevent recording contents from being listened to by persons other than persons concerned, by detecting and collating group information of the terminal recorded in a recording device and group information of the terminal for which the read operation for the recording device is performed. CONSTITUTION:In case that information stored in recording device 7 is read from extension telephone set 2, central control circuit 8 is started to read out presentative selection information corresponding to extension telephone set 2, which is stored in presentative selection group memory circuit 12, and this information is transmitted to collating circuit 14 when extension telephone set 2 dials the read special number for recording contents from recording device 7 after oscillation tone connection. Meanwhile, presentative selection information of extension telephone set 1 stored in temporary memory circuit 10 is read out and is transmitted to collating circuit 14. These information are compared with each other by collating circuit 14; and if they agree with each other, recording track connecting circuit 15 is started to listen to recording information from telephone set 2.
