Abstract

PROBLEM TO BE SOLVED: To allow a caller to save labor and time for entering the telephone number of the caller himself, when the caller requests call-back. SOLUTION: When a call is incoming from a trunk line to a key telephone system 1, and the user of a telephone set 7 is unable to answer due to the absence of the user, this incoming call is transferred to a voice mail device 8. A message from the caller is stored in a storage part 82 of the voice mail device 8. On the other hand, at the time of incoming a call from the turn line, an modem signal receiving part 6 of the key telephone system 1 receives a caller number transmitted from the trunk line by a caller telephone number service, and a central controlling part 2 transmits the received result to the voice mail device 8. The voice mail device 8 stores this in the storage part 82 by making it correspond to the message. When the message is confirmed, the caller number corresponding to the message is read, and transmitted from a dial transmitting circuit 42.

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

Referring to FIG. 1, an embodiment of a key telephone system with a voice mail function according to the present invention comprises a key telephone device 1, an extension telephone 7, and a voice mail device 8. Are shown.

The key telephone apparatus 1 includes a central control unit 2 for controlling the entire apparatus, and a time-division switch 3 for forming a communication path.
A telephone line interface unit 4 for controlling the capture and release of the telephone line, a telephone interface unit 5 for communicating with the telephone 7 and the voice mail device 8, and a caller sent from the telephone line when an external line arrives. A modem signal receiving unit 6 for receiving a telephone number and notifying the central control unit 2 of the telephone number.

The central control unit 2 comprises a microprocessor unit (MPU) 21 and a main storage unit 22 in which a control program is written. The office line interface unit 4 includes an office line interface circuit 41 for capturing and releasing office lines, and a dial sending circuit 42 for sending dials.
And a control unit 43 for controlling these units.

The telephone 7 includes a control unit 71, a dial keypad 72, a handset 73, and a ring tone transmitting unit 74.
It is composed of The voice mail device 8 includes a control unit 81 that controls the operation of the voice mail device, and a storage unit 82 that stores a message and a caller number.

Next, the operation of the embodiment of the present invention will be described with reference to FIGS. First, in the message reception and caller number registration operations, when an outside line incoming call is detected by the office line interface circuit 41 of the office line interface unit 4 (step 1: S1), the incoming call information is transmitted from the control unit 43 to the central control unit 2. (S2). MPU of central control unit 2
The control unit 21 controls the time-division switch 3 in accordance with the control program of the main storage unit 22 to make an incoming call to the corresponding telephone 7 (S3). The control unit 71 of the telephone 7 receives this, and makes a call by the ringing tone transmitting unit 74 (S4).

Here, the MPU 21 determines whether or not there is a telephone response (S5), and when a response is obtained, performs a normal operation for connecting the calling side and the called side (S6). On the other hand, when a response is not obtained, that is, when the user of the telephone 7 is absent or does not respond to the incoming call for some reason, the MPU 21 of the central control unit 2 operates according to the control program of the main storage unit 22. The division switch 3 is controlled to transfer the incoming call from the telephone 6 to the voice mail device 8 (S7).

In the voice mail device 8, the control section 81 reads out a response message to record a message to the corresponding user from the storage section 82, and sends it to the local line sender (S8). The caller sends a message to the voice mail device 8 according to this, the message is received by the voice mail device 8, and the recorded content is stored in the storage unit 82 (S9). When the caller is recording a message in the voice mail device 8, the voice mail device 8 notifies this information to the MPU 21 (S
10).

On the other hand, the caller ID notification by the calling telephone number service sent from the office line is received by the modem signal receiving unit 6 via the office line interface circuit 41 (S1).
1). The modem signal receiving section 6 converts the caller number into a format of data used inside the key telephone apparatus, and notifies the MPU 21 of the central control section 2 (S12).
When receiving the recording information in S10, the MPU 21 notifies the voice mail device 8 of the caller number already received (S13).

The control unit 81 of the voice mail device 8 determines whether or not the recording of the message has been completed (S14). If the recording has not been completed, the process returns to S9. The corresponding numbers are stored in the storage unit 82 (S
15).

Next, in the callback operation, when the user of the telephone 7 inputs an access code from the dial keypad 72 to confirm the recorded contents, the control unit 71 of the telephone 7 receives this (S21), This data is sent from the control unit 71 to the control unit 81 of the voice mail device 8 via the MPU 21 of the central control unit 2 (S22).

The control unit 81 of the voice mail device 8 receives this message and reproduces and outputs a message addressed to the user from the storage unit 82 (S
23) After that, a dial input request message for confirming whether or not to perform the callback is read out from the storage unit 82 and transmitted to the user of the telephone 7 (S24). Telephone 7
If the user wants to call back, the user inputs a dial code for instructing the callback from the dial keypad 72, and the control unit 71 determines and recognizes this (S2).
5), this dial information is sent from the control unit 71 to the central control unit 2
Control unit 81 of voice mail device 8 via MPU 21
Sent to Upon receiving this, the control unit 81 stores in the storage unit 82
To retrieve and extract the caller number associated with the message currently being reproduced and output (S26), send the extracted caller number to the MPU 21, and dial the caller number, that is, call back. To MPU21
(S27).

The MPU 21 of the central control unit 2 instructs the control unit 43 of the central office interface unit 4 to capture the local line and send out the dial, and also controls the time division switch 3 to communicate with the telephone 7 and the voice mail device 8. The communication path between the office line and the telephone 7 is released, and the communication path between the office line and the telephone 7 is established. On the other hand, the control unit 43 of the office line interface unit 4 controls the office line interface circuit 41 to capture office lines, and based on the dial information from the central control unit 2, a dial sending circuit 42.
Sends the corresponding caller number (S28).

[0021]

As described above, according to the present invention, when a message is recorded by the voice mail device connected to the key telephone device, the caller number sent from the central office is associated with the message. The stored caller number is read out and sent when confirming the message, so if the caller wants to request a callback when recording the message, dial his / her own phone number. It is not necessary to input, and the convenience of the subscriber can be improved.
