BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described. As the present embodiment, a case where the present invention is applied to a voice storage device for PHS will be described.

First, referring to FIG. 1, the system configuration of the PHS including the voice storage device 1 will be described. Voice storage device 1
Is connected to the public communication network 3, for example, an ISDN communication network which is a communication network having a caller number display function. In addition, the voice storage device 1 uses the caller terminal 5 via the public communication network 3,
It is connected to a radio base station 7, and is further connected to a PHS telephone 9 as an arbitrary mobile communication terminal via a radio line via the radio base station 7.

Next, with reference to FIG. 2, the configuration of the voice storage device 1 will be described. The voice storage device 1 is connected to the ISDN communication network via the call control unit 11. The call control unit 11 performs recording, reproduction, setting operations, and call control of call origination, call termination, and call end according to the present invention. A central processing unit 13, a memory 15, a voice storage unit 17, a guidance storage unit 19, and a service control unit 21 are connected to the call control unit 11. The voice storage unit 17 is a memory for recording a message addressed to the user, the guidance storage unit 19 is a memory for holding various guidances output from the voice storage device 1, and the service control unit 21 stores a timer 23.
