Abstract

PURPOSE:To complete the purpose of a call only with a reply message depending on an opposite party and to attain delicate reception by using a DTMF(Dual Tone Multi-Frequency) signal after line connection so as to identify the opposite party and replying with a response message in response to the said opposite party. CONSTITUTION:When an incoming call comes from an opposite party and the line is connected, a reply message 20 is started for transmission. When a #signal is sent, a DTMF signal is converted into a code and stored in a RAM 4. When no # signal is sent, the communication is terminated. When a * signal is sent, the number stored in the RAM 4 is read. Then the said reply message is read from RAMs 21-24 storing the reply message of the opposite party in response to the number and sent to a telephone line 1 through a network controller NCU 2. When it is discriminated that the relevant number does not exist, the communication is terminated without further processing. However, the initial reply message is being sent in this case. Moreover, when no DTMF signal comes, only the initial reply message is sent.

Description

[Detailed description of the invention] [Industrial application field] This invention relates to an answering machine.

[Prior Art] Conventionally, answering machines have been able to automatically record and store messages from other parties even when the user is not present.

Furthermore, when a user receives a message from the other party, the number of messages to which the user can respond is only 1 to 2.3 messages.

[Problems to be Solved by the Invention] As described above, in the conventional example, when a message is received by an answering machine, the messages that the user can set as a response are limited to 1 to 2 or 3 messages. Even if it is possible to set multiple messages, the only way to use them is to switch between them depending on the time of day or to change them sequentially according to incoming calls, and it is not possible to control how to respond differently to each recipient. There was a problem.

This invention was made in order to solve the problems of the conventional example as described above.
Tone Multi-Frequency) identification means identifies the other party, and the message setting means makes it possible to respond with a response message suitable for the other party,
You can respond in detail, and depending on the recipient, you may be able to complete the transaction with just an @ reply message, so in that case there is no need to record the recipient's message, and you can save on media such as tapes and ICs. purpose.

(Means for Solving the Problem) Therefore, in this invention, the DTMF after line connection is
The message setting means has an identification means for identifying the other party by a signal, and a message setting means for setting a message for each predetermined party, and when receiving the message, the message setting means corresponds to the other party identified by the identification means. This object is achieved by an answering machine which is equipped with a control means to respond to unidentified parties with a common message.

(Function) The answering machine of the present invention identifies the other party using the DTMF signal after the line is connected by the identification means, sets a message for each predetermined party by the message setting means, and when receiving the message, 'the party identified by the identification means' A message setting means corresponding to the party is used to respond to the party, and a common message is controlled to respond to the party who is not identified.

〔Example〕

An embodiment of the present invention will be described below based on the drawings. FIG. 1 is a block diagram showing the configuration of an answering machine which is an embodiment of the present invention, and FIG. 2 is a flowchart for controlling the operation of this embodiment.

In Fig. 1 of the drawings, A is an identification means, which is composed of a microprocessor (CPU) 5,
F Freq% (Dual Tone Multi-Freq
This is a means of identifying the other party based on the ``uency''. B is a message setting means, and in this embodiment, 4 predetermined
It is comprised of RAM (Random Access Memory) 21 to RAM 24 in which response messages (hereinafter referred to as messages) for each person are stored. Control means C is composed of a CPU 5, and upon reception, the message setting means B responds to the party identified by the identification means A, and the response message stored in the RAM 20 is sent to the party who is not identified. This is means for controlling to respond with a certain common message 20a.

1 is a telephone line, 2 is a network control unit (hereinafter referred to as NCU), 3 is a dial numeric keypad, and 11 to 14 are 4 mentioned above.
It is a one-touch dial button switch for humans. still,
Messages 21 to 24 are created by first pressing one of the one-touch dial button switches 11 to 14 and then performing a response message recording operation.

Next, the operation of this embodiment will be explained with reference to the control means C.
This will be explained using the flowchart shown in the figure.

In the flowchart of FIG. 2, after a call is received from the other party and the line is connected, a response message 20 is first sent in step S1.
begins to be transmitted, and the process advances to step S2. When a mouth signal is sent in step S2, the DTMF signal is converted into a coat in step S3 and stored in the RAM 4. If no mouth signal is sent in step S2, the process ends. Step S
When the figure signal is sent in step s5, the number stored in the RAM 4 is read out, and in step s5, the response message of the other party corresponding to that number is stored in the RAM 2! or 2
The response message is read out from the telephone line !4 through the network control unit (NCU) 2 in step S6. Send to.

When it is determined in step s5 that there is no corresponding number,
Exit. However, even in this case, the first response message continues to flow. Further, if no DTMF signal is received, only the first response message is sent.

Note that although the DTMF signal received after the line is connected starts with the surrounding signal in the above embodiment, it may also be a signal from another country.

Further, the number based on the received DTMF signal may be, for example, the telephone number of the other party registered in the one-touch dial button switch, or the number of the one-touch dial button.

Furthermore, even if it is an individual message, it may be possible to delete it if the time limit has passed. Alternatively, you can have multiple individual messages and switch between them depending on the time of day.

〔Effect of the invention〕

As explained above, according to the present invention, D
It becomes possible to identify the other party using the TMF signal and respond with a response message appropriate for the other party, which has the effect of allowing detailed response.

Further, depending on the recipient, the business may be completed with just the response message, so in that case there is no need to record the recipient's message, which has the effect of saving media such as tape or IC.
