[Example] Hereinafter, an example according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of an embodiment according to the present invention, and 1 in the figure is a block diagram for executing the control procedure shown in FIG. 3 and FIG. A central processing unit (hereinafter referred to as rcPUJ) in charge of overall control, 2 a read-only memory (ROM), 3 a random access memory (RAM), 4 a magnetic disk device which is an external storage device, and 5 a Line L1. From L2,
A converter 6 converts analog data sent through the matsive transformer 12 into digital data, and also converts digital data from the compression/expansion device 6 into analog data. ,
Also, a compression/decompression device 7 decompresses compressed digital data, and 7 is a line L1. A called detection circuit detects an incoming call from line L2, 8 is an answering mode changeover switch for switching whether or not to energize this device, and 9 is a call detection circuit for detecting an incoming call from line L1. A dial pulse detection circuit analyzes the dial pulse signal from L2 and detects the sent signal value, 10 is the line Ll, an MF that analyzes the MF signal from L2 and detects the sent signal value.
A signal detection circuit 11 is connected to the line LL under the control of the called detection circuit 7.
, a relay contact for creating a DC loop in L2, 14
is line L1. A switching circuit for connecting L2 to the telephone 30, 15 an external interface section for connecting the present device to an external device (eg, computer device 50), and 30 a telephone.

FIG. 2 shows an external view of this embodiment having the above configuration.

The same components as in FIG. 1 are given the same numbers.

In the figure, reference numeral 20 denotes an audio data processing device having the configuration shown in FIG. 1, on which a telephone 30 is installed. 4 is a magnetic disk device shown in FIG.

The operation of this embodiment having the above configuration will be explained below with reference to the flowcharts of FIGS. 3 to 5.

When the device is powered on, step S1 shown in FIG.
The called detection circuit 7 connects the line L1. Monitor calls from L2. Here, if there is a call from the caller, the call detection circuit 7 detects this and the process proceeds from step S1 to step S3. Here, it is checked whether the answering mode selector switch 8 is set to the answering mode and it is not a dolphin, and if it is not the answering mode, the switching circuit 14 remains connected to the telephone 30 side and does nothing.

Therefore, as shown in step S4, the telephone 30 continues to ring, and when the caller presses the on-footer or picks up the handset of the telephone 30 in step S5 (off-hook), the telephone 30 becomes ready to talk, and in step S6 Make the call as shown. Then, when the call ends, the user hangs up the telephone receiver (goes on-hook) in step S7 and ends the call.

During this time, the call operation is the same as using a normal telephone.

On the other hand, when the answering mode selector switch 8 is in the answering mode, the process advances to step S10, and the called detection circuit 7 controls the switching circuit 14 to disconnect the telephone 30 from the lines LL and L2. Subsequently, in step S11, the relay contact 11 is closed, a DC loop is generated in the lines Ll and L2, and a response is generated. As a result, it becomes possible to make a call, so step 312 follows.
The CPU then starts up the magnetic disk device 4 and reads out the message data to be responded to. Then, in step S13, the response message is decompressed by the compression/decompression device 6 and sent to the converter 5.The converter 5 converts the decompressed digital data into analog data, and connects the line to L2.
Send to.

The response message in this example is "Do you want to leave a voicemail? If you leave a voicemail, press ■ on your phone, if you do not leave a voicemail, press ■.
Please enter j.

The caller listens to this response message, determines whether to use it as an answering machine or a voicemail device (described later), and inputs the corresponding number. If the phone you are calling is a button phone, press and input the corresponding numeric button; if the phone is a normal rotary dial phone without a button, turn the corresponding dial number to input the number. conduct.

Therefore, in step S14, the dial pulse detection circuit 9
, or the MF signal detection circuit 10 waits for either the dial pulse signal or the MF signal, which is the telephone number signal, to be detected, and when either of the telephone number signals is received, the process advances from step 314 to step S15, where the received telephone number signal is detected. It is checked whether the received telephone number signal is 1'' or not. If 1'' is sent, the process advances to step S16 and the answering machine process shown in FIG. 4 is executed. Thereafter, in step S20, the relay contact 11 is opened, the DC loop is opened, the lines L1 and L2 are restored, and the switching circuit 14 is switched to the telephone 30 side. Then, the process ends and the process returns to step S1.

On the other hand, the telephone number signal sent in step S15 is 1.
If not, the process advances to step S17, where the command message stored in the magnetic disk device is read out, the command message is decompressed by the compression/decompression device 6 as in step S13, and sent to the converter 5, where the converter 5 decompresses the command message. The converted digital data is converted to analog data and sent to lines LX and L2.

The command message in this example prompts you to enter a command number to select which voicemail function to perform. Please enter the V command number 1
However, the message sent to the caller is not limited to this.

The caller listens to the response message and enters the number corresponding to the desired voice mail function. Therefore, step S1
Step S8 waits for the telephone number signal from the caller to be sent, and when the telephone number signal is detected, the process proceeds to step S19, where command processing corresponding to the telephone number signal shown in FIG. 5 is executed.

Then, the process advances to step S20.

Next, the answering machine processing in step S16 will be explained with reference to the flowchart of FIG.

First, in step S41, a response message as an answering machine is read from the magnetic disk device 4 in the same manner as in step S12, and the read message is sent to line L11L2 in the same manner as in step 313. Here, as a message, enter ■ to start the answering message, and input ■ to end the message.1 will be sent. Next, in step S42, the caller waits for a number input, and if there is a telephone number available, it is checked in step S43 whether °゛1'' has arrived.If it is not °゛1'', the process returns to step S42;
In the case of “1°”, the process advances to step S44. Analog voice information to be recorded from the calling side is input to the converter 5 via the transformer 12. Therefore, the converter 5
converts the received analog audio information sent in step S44 into digital information and sends it to the compression/expansion device 6.

In the compression/expansion device 6, the converter 5
The digitized data is compressed using a known method and sent to the CPUI in predetermined units. CPUI in step S46
This compressed data is written to the magnetic disk device 4. Then, in the following step S47, the calling side checks whether 2'' has been input as a telephone number signal, and if "2" has been manually input, the process proceeds to step 34B, and if it has not been input, the process returns to step S44, and the process is sent. Continue writing the incoming audio information to the magnetic disk device.

On the other hand, in step S48, a file number is assigned and registered to the audio information written in the magnetic disk device 4. Then, the process ends and returns.

Next, the command processing in step S19 will be explained with reference to FIG.

First, in step S51, the CPU selects the magnetic disk device 4.
Among the digital audio data files recorded in the data file, the data file having the number specified by the telephone number signal is located. Then, in the next step S52, the audio data of the file located at the beginning is read from the magnetic disk device 4, and the audio data read out in step S53 is compressed/
The data is sent to the decompression device 6, and decompression processing is performed on the compressed data. The compression/expansion device 6 transfers the decompressed audio data to the converter 5.

The converter 5 converts this expanded digital audio data into analog audio data in step S55, and converts the expanded digital audio data into analog audio data in the transformer 12.
It is sent to lines LL and L2 via. Then, in step S56, it is checked whether or not the output of the data file from the magnetic disk device 4 has been completed. If the output of the data file has not been completed, the process returns to step S52 and the current data file is read and played back. continue.

If the output of the data file has been completed, the process ends and returns.

As explained above, according to this embodiment, it is possible to quickly respond to calls from the line (public communication line), and by storing response messages in the magnetic disk device 4, a wide variety of messages can be retained. can.

In addition, by recording the transmission message from the caller in the magnetic disk device 4, random reading is possible.
It also becomes easier to search for a desired message.

In addition, the desired transmission message stored in the magnetic disk device 4 can be accessed and read out onto the line by a simple operation that does not require special equipment, such as inputting a telephone number signal from the telephone of the calling party. You can achieve the following voicemail functions.

(1) Mailbox function: If you post a message in the recipient's mailbox, the recipient can retrieve the message at their convenience.
