〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a telephone exchange according to the present invention.

This telephone exchange includes a switching network 6, a central control unit 7, a main storage unit 9, and a CRT 8. It includes an output device consisting of a printer 82, a CRT control device 10, a recording device 1, an interface circuit 2, and a three-way trunk 3, and accommodates subscriber telephones 4 and 5. The recording device 1 is connected to the exchange network 6 via the interface circuit 2, and when the three-party call trunk 3 is connected, it notifies the central controller 7 of the recording start position flag, and also sends the recording start position flag to the central controller 7. recording from the flag specified by the instructions,
Play and cut. The main storage device 9 stores recording service subscriber phone numbers and passwords in addition to the known information stored in the exchange. Call information consisting of a location flag and call end time is registered for each call.

Next, the operation of this embodiment will be explained.

Assume that subscriber phone 4 has subscribed to a recording service and that a call has been received from subscriber phone 5. Central control bag M
7 checks whether the telephone number of the subscriber telephone 4 is subscribed to the recording service by dialing the subscriber telephone 5, and when it is confirmed that the telephone number is subscribed to the recording service, the subscriber telephone 4. Recording device 1 between 3
and start the recording device Ml. The recording device 1 sets a flag indicating the position where recording is to be started and notifies the central control unit W7 of the flag. The central control device 7 connects the subscriber telephone 4
The telephone number, the other party's telephone number, the connection time, the recording device 1, the recording start position flag, and the end time of the call are registered in the main storage device 9. After that, when the subscriber of the subscriber telephone 4 dials the recording/playback request number, own telephone number, and PIN, the central control unit #7 confirms the PIN and searches for call information using the recording/playback requester's phone number. to read the flag,
