Abstract

(57) [Summary] [Problem] To reduce the communication cost of the other party who receives a call in answering machine mode. When an incoming call is detected when an answering mode is selected on a telephone set, a received caller number is sent to a control circuit. When the caller number is sent, the control circuit 7 searches the caller number stored in the incoming call record table 81 of the memory 8 and checks whether the same telephone number as the sent caller number is stored. If the same telephone number as the transmitted caller number is stored in the incoming call record table 81, it is determined that there is an incoming call from the same caller before that, and the line is set as a non-response. Disconnect.

Description of the Related Art Generally, an answering machine transmits a response message in response to an incoming call when an incoming call is received while the answering machine is set to an answering mode. When the setting of the answering mode is cancelled, it is often the case that a call is made again to the other party who received the call during the answering mode. When making a call back to the other party in this manner, the telephone number of the other party is checked by looking in the address book or by writing down the telephone number recorded as a voice message.

[0003]

However, if a response message is transmitted by responding to the other party every time an incoming call is made in the absence mode, if the same party repeatedly receives a call, the other party sends the same message. I had to listen repeatedly and had to pay a telephone charge each time. Also, when making a call to the other party who received a call while in Answering Machine, you can check the phone number of the other party by looking in the address book, or by writing down the phone number recorded as a voice message and checking it. , It is complicated to check the phone number and the phone number is easy to make mistakes,

DESCRIPTION OF THE PREFERRED EMBODIMENTS A communication device according to the present invention comprises a switching matrix connected to a line interface,
It has a telephone, a terminal interface connecting the switching matrix and the telephone, a PB signal control circuit, a data modem, and a control circuit and a memory for controlling the operation of the entire communication device. The memory has an incoming call record table. The incoming call record table has an area for storing an incoming date, an incoming time, and a caller number, and stores the date and time when there is an incoming call and the caller number of the called party.

When an incoming call is detected by the line side interface when the answering mode is selected by the telephone, when the line side interface closes the line DC loop, the caller number sent from the central office is transmitted to the data modem. Received by
The received calling party number is sent to the control circuit. When the caller number is sent, the control circuit searches the caller number stored in the incoming call record table of the memory and determines whether the same telephone number as the sent caller number is stored. . As a result of this determination, if the same telephone number as the transmitted caller number is stored in the incoming call record table, it is determined that there is an incoming call from the same caller before that, and the line is determined as a non-response. Disconnect. In this way, when the same caller repeatedly receives an incoming call during absence, the second and subsequent calls do not respond, thereby preventing the caller from paying unnecessary communication costs.

[0008]

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. As shown in the figure, the communication device includes a switching matrix 2 connected to a plurality of line interfaces 1a-1n, a plurality of telephones 3a-3i, and terminal interfaces 4a-4i connecting the switching matrix 2 and the telephones 3a-3i. And a control circuit 7 for controlling the operation of the PB signal control circuit 5, the data modem 6, and the entire communication device, and a memory 8. The data modem 6 sends the calling number received via the line interface 1 and the switching matrix 2 to the control circuit 7. The control circuit 7 stores the transmitted caller number in the memory 8. The memory 8 has an incoming call record table 81 and a callback number management table 82 for each of the telephones 3a to 3i.

As shown in FIG. 2, the incoming call record table 81 has an area for storing an incoming call date, an incoming call time, and a caller's number, and the date and time when there is an incoming call and the caller of the called party. Remember the number. Callback number management table 82
As shown in FIG. 3, there is provided an area for specifying the telephone number of the other party and the presence of an incoming call, and the telephone number of the other party to be called again when receiving a call in the absence mode is registered in advance.

A process of responding to an incoming call when the answering mode is selected on the telephone 3a of the communication apparatus having the above-described configuration will be described with reference to a flowchart of FIG.

When an incoming call is detected by the line-side interface 1a (step S1), the line-side interface 1a closes the DC loop of the line, and when the caller number sent from the central office exchange is received by the data modem 6, The received caller number is sent to the control circuit 7 (step S2). When the caller number is sent, the control circuit 7 searches the caller number stored in the incoming call record table 81 corresponding to the telephone 3a in the memory 8 and finds the same telephone number as the sent caller number. It is determined whether it is stored (steps S3, S4).
As a result of this determination, if the same telephone number as the transmitted caller number is stored in the incoming call record table 81, it is determined that there was an incoming call from the same caller before that, and the line Is cut (steps S5 and S12). In this way, when the same caller repeatedly receives an incoming call during absence, the second and subsequent calls do not respond, thereby preventing the caller from paying unnecessary communication costs.

When the same telephone number as the transmitted caller number is not stored in the incoming call record table 81,
The transmitted caller number is stored in the incoming call record table 81 together with the incoming date and time (step S6). Next, the control circuit 7 searches the callback number management table 82 corresponding to the telephone 3a in the memory 8 and determines whether the same telephone number as the calling number stored in the incoming call recording table 81 is registered. Is confirmed (step S7).
As a result of this check, if the same telephone number as the calling number received this time is registered, it is specified that there is an incoming call to the corresponding telephone number in the callback number management table 82 (steps S8, S9). Thereafter, the call is answered and a voice message is sent to the caller, and then the communication is cut off (steps S10, S11, S12). If the same telephone number as the caller number received this time is not registered in the callback number management table 82, the call is immediately answered, a voice message is sent to the caller, and then the communication is cut off (step). S7, S10 to S12).

Next, a description will be given, with reference to the flow chart of FIG. 5, of an operation for making a call again when the answering mode is released to the called party when the answering mode is selected.

When the answering mode of the telephone 3a is released (step S21), the control circuit 7 stores the telephone 3 in the memory 8.
The callback number management table 82 corresponding to a is searched (step S22). Then, the telephone number specifying that there is an incoming call is read out and displayed on the display unit 31 of the telephone 3a as shown in FIG.
23). When the person who confirms this display selects the telephone number displayed on the display unit 31 and presses the call button, a call is made to the selected telephone number and a normal call is made (step S2).
4, S25). When this transmission is completed, the same transmission is performed for the next telephone number (steps S26 and S23). When the transmission is performed for all telephone numbers for which there is an incoming call in the callback number management table 82, the process ends ( Step S26). In this way, it is possible to make a telephone call only to the necessary destination. Further, since a call is displayed on the telephone 3a to the telephone number of the other party, erroneous calling can be prevented.

[0015]

As described above, according to the present invention, the caller number received when the answering mode is set is confirmed, and no response is made when the same caller number is received again. Therefore, even if the caller repeatedly makes a call, there is no need to pay unnecessary communication costs, and the communication costs can be reduced.

Also, it is checked whether or not the caller ID received when the answering mode is set is a telephone number registered in advance, and the calling number coincides with the registered phone number when the answering mode is canceled. Because we display caller ID,
It is possible to accurately recognize the telephone number of the other party who makes the call again.

Furthermore, since the automatic call is made to the telephone number selected from the telephone numbers displayed when the answering machine mode is released, the outgoing call can be prevented.
