[0002]

2. Description of the Related Art In general, in a telephone device, when an incoming signal arrives at a line from an exchange based on a calling operation of a caller, a ring tone is sounded from an accommodated telephone terminal to notify the incoming call.
In this case, when the telephone device detects an incoming response operation on the telephone terminal side, it stops the ringing tone of the telephone terminal, closes the DC loop of the incoming line, and shifts to a call between the caller and the telephone terminal side. ing. In this case, the call fee is charged to the caller.

[0003]

As described above, the charge of the call based on the call originating by the caller is charged to the caller. For this reason, for example, when an employee of the company or a telecommuter calls the company for business use, the call charge is similarly borne by the calling party, but for such business calls, There is a strong demand for the company to pay the charges properly, rather than the individual caller. Therefore, an object of the present invention is, for example, when an employee or the like of a company makes a business call to the company, it is an object of the present invention to allow the company to appropriately bear the call charge.

[0004]

According to the present invention, there is provided a receiving means for receiving a calling number which is a telephone number of a caller arriving on a line prior to a call signal when the caller originates a call. A memory in which telephone numbers are registered in advance, detecting means for detecting a match between the received calling number and the telephone number in the memory, and calling after the detecting means detects a match between the calling number and the telephone number in the memory. Upon detecting the calling abandoning's automatic and ringtone sounding means for sounding the ring tone, with sets the recording mode when the response operation of the incoming after ring tone ringing in the ringtone sounding means is not detected Jo Tokoro time to caller A transmitting means for transmitting a signal and a control means for recording a signal from the caller via a line to a recording means when a response of the caller to automatic transmission of the transmitting means is detected.

[0007] As described above, the functional telephone device having the above-described configuration has a function of receiving the calling number notified from the exchange, and the function of notifying the calling number is shown in the sequence of FIG. It will be described based on the following. In the drawing, reference numeral 50 denotes a calling side device, reference numeral 60 denotes an exchange, and reference numeral 70 denotes a called side device which is this functional telephone device. In FIG. 4, the exchange 60, which has received the telephone number of the called side transmitted from the calling side apparatus 50 in step S1, performs steps S2 and S3 before transmitting the calling signal to the called side apparatus 70, respectively. Polarity reversal of lines L1 and L2, and I
An AC signal near 16 Hz indicating the D receiving terminal activation signal is intermittently transmitted to the called device 70 for a predetermined time.

[0008] These signals are detected by the open-loop reciprocity detecting circuit 11 and the incoming call detecting circuit 14 of the called device 70. In this case, in the called device 70, the loop closing circuit 2 closes the DC loop of the lines L1 and L2 in step S4, and returns a primary response to the exchange 60. Then
The exchange 60 transmits the calling number, which is the telephone number of the calling device 50, to the called device 70 by a modem signal. The called device 70 receiving this calling number via the modem 13
Releases the DC loop of the lines L1 and L2 closed by the loop closing circuit 2 in step S6, thereby notifying the exchange 60 of the reception of the calling number.

At this time, the received calling number is displayed on the display unit 16 of the called device 70, and the called device then issues a normal 16 Hz one-second ringing and a two-second pause transmitted from the exchange 60 thereafter. The buzzer BZ makes an incoming call ringing in response to the call signal, and it can be determined at this time whether or not to respond to the incoming call based on the calling number being displayed. In response to this paging signal, the called device 70 closes the DC loop of the lines L1 and L2 by the loop closing circuit 2 or closes the DC loop by off-hook operation in step S7, so that the switch 60 goes to step S8. Sends a secondary response signal.

Then, in the exchange 60, the polarities of the lines L1 and L2 are reversed in step S9, and this is
And the charging operation is started. Thereafter, a call is made in step S10, and thereafter, the process ends with the call termination in step S11. It should be noted that billing is not performed unless the direct current loop of the lines L1 and L2 is closed as in step S8 for the transmission of the calling signal.

Next, the operation of the main part of the function telephone apparatus having the function of receiving the calling number notified from the exchange side when an incoming call is received will be described in detail with reference to the flowcharts of FIGS. When the primary response by the loop inversion of the lines L1 and L2 in response to the polarity reversal of the lines L1 and L2 and the ID receiving terminal activation signal sent from the exchange when the caller originates is returned to the exchange, the exchange described above. As described above, the calling number is notified by the modem signal. In step S21, it is determined whether or not the calling number is notified. Then, the notified calling number is received, and the determination in step S21 is “Y”.
Then, the loops of the lines L1 and L2 are opened, a reception completion signal of the calling number is transmitted to the exchange, and a calling signal is transmitted from the exchange. In step S22, the reception calling number and the telephone number registered in the memory 15 are registered. Is determined.

If the received calling number matches one of the telephone numbers registered in the memory 15 in advance and the determination in step S22 is "Y", the CPU 1 stores the calling number in the memory 15 and In step S23, the built-in automatic transmission monitoring timer is activated, and it is monitored whether or not the caller goes on-hook within a predetermined time measured by the activated timer. Note that even during the operation of such a timer, unless the caller goes on-hook to abandon the call, the calling signal from the exchange continues to reach the lines L1 and L2.

Here, when the caller goes on-hook within a predetermined time based on the time measured by the timer, the lines L1 and L
2 does not receive a call signal, and therefore the incoming call detection circuit 1
When the call signal is no longer detected via the CPU 4, the CPU 1 determines that the "caller line disconnected?" Of step S24 is "Y". In this case, the CPU 1 proceeds to step S26 in FIG.
The “automatic transmission process” shown in FIG. Even if the timer expires and the determination in step S25 becomes "Y", the caller does not abandon the call, and therefore, if the call signal is still arriving on the lines L1 and L2, the caller Assuming that a call has been made for an urgent matter, normal incoming call processing is performed in step S27.

That is, in the normal incoming call process in step S27, the switch SW is first driven to close its contact so that the calling signal from the incoming call detection circuit 14 is output by the buzzer B
Z to output a ringing tone. Then, when the user of the apparatus that has listened to the incoming ringing sound goes off-hook, the hook switch HS2 is closed, and an incoming call is made with the caller. When the calling number is not notified at the time of the incoming call and the determination in step S21 is “N”, or when the notified calling number does not match the telephone number in the memory 15, the determination in step S22 is “N”. If so, the process proceeds to step S27 to perform a normal incoming call process.

FIG. 3A is a flowchart showing a specific processing operation of the automatic transmission processing executed in step S26 of FIG. That is, when the disconnection of the caller line due to the on-hook of the caller is detected and the determination in step S24 of FIG. 2 becomes “Y”, in step S31 of FIG. 3A, a timer for monitoring the call operation for a predetermined time is started. . Then C
PU1 drives the ringer RNG in step S32 to cause the buzzer BZ to emit a ringing sound.

When the user of this apparatus goes off-hook due to the ringing tone, the DC loops of the lines L1 and L2 are closed by closing the hook switch HS2 and the CP is closed.
U1 detects the state of the hook switch HS1 interlocked with the hook switch HS2, and determines "Yring line capture?" In step S33 as "Y". In this case, the CPU 1 stops the ringing tone ringing output from the ringer RNG, and controls the voice recording / reproducing circuit 7 in step S34, thereby reproducing the voice message previously recorded in the recording / reproducing IC 6 and transmitting the voice message from the speaker SP. Send out. Here, if the apparatus is installed in a company, for example, and a telephone call is received from an employee, in step S34, the recording / reproducing I
From C6, a voice message to the effect that "there has been a call from an employee" is reproduced and notified to the user of this apparatus. Thereafter, the CPU 1 shifts the processing to step S35, and executes a return transmission processing shown in FIG.

On the other hand, when the ringing sound is transmitted from the buzzer BZ and the user of the apparatus does not respond to it and the timer times out and the determination in step S36 becomes "Y", , Ringer RN in step S37
Stop ringing sound output from G, and execute step S3.
After setting the recording mode in the memory 15 at 8, the loop closing circuit 2 is driven to close the DC loops of the lines L1 and L2. Then, thereafter, the return transmission processing of step S35 is executed.

Next, in the return transmission processing of FIG.
First, in step S41, a calling process for reading out the calling number stored in the memory 15 and giving it to the dial circuit 3, and outputting the dial signal from the dial circuit 3 to the capture lines L1 and L2 is executed. Next, in step S42, it is determined through the reverse detection circuit 12 whether or not there is a response from the other party (response from the caller). When the response from the other party is detected, one of the following two processes is performed.

That is, when the recording mode is set in the memory 15 and the determination in step S43 is "Y", a message indicating absence is sent from the recording / reproducing IC 6 to the sender in step S44, and then in step S45. A recording process for recording the message of the other party (sender) on the recording IC 6 is executed. Then, when the recording ends, a call termination process is performed and the process ends. If the recording mode is not set in the memory 15 and the answer is "N" in the step S43, a normal telephone call is made between the user of the present apparatus that went off-hook and the caller (step S46).

As described above, when the caller makes a call to the present device, the present device receives the calling number notified before the arrival of the call signal, and the received calling number is registered in the memory 15. Then, after the caller goes on-hook, a call is automatically sent to the caller and the caller is contacted. Therefore, the memory 15 of the apparatus installed in the company
If the employee's telephone number is registered in advance in the office, if the employee makes a business call to the company, the device can return to the employee and make a call to the employee to contact the employee. The company can accurately bear the call charges based on the outgoing call.

If the user of this apparatus is absent and cannot send a call back to the employee, the call is automatically sent to the employee, and when the employee answers, a message indicating the absence is sent out.
In order to record the message from the employee to the recording / playback IC6,
Employees can contact the company without incurring call charges. Further, even during the absence mode, by switching to the call mode by operating the apparatus, it is possible to make a call between the employee and the user of the apparatus. In this embodiment, an example of a single telephone device accommodating one line has been described, but a key telephone device or an exchange accommodating multiple lines can be similarly realized. Also,
By adopting the following method as an example other than the above, it is possible to quickly contact the caller.

That is, as soon as an on-hook of a caller is detected, an automatic call is sent to the caller in a recording mode and an incoming call is sounded. When the user of the apparatus goes off-hook, the above message is sent to the user. Switch to call mode. At this time, if the message message of the sender is
Even during recording on C6, by switching this to the call mode, a call between the caller and the user of the present apparatus is enabled. As a result, it is possible to quickly contact an employee (caller) who has made a call from a mobile phone or the like. In addition, the apparatus accommodates multiple lines, and when the calling number arriving at the first line matches the telephone number in the memory 15 based on the caller's call, the call is transmitted using the second line. By automatically sending the caller, the time required for contacting the caller can be further reduced.

[0023]

As described above, according to the present invention, when a caller makes a call to the present apparatus, the present apparatus receives the calling number arriving before the calling signal, and the received calling number is stored in the memory. If it is registered in the company, the caller is automatically sent back to the caller based on predetermined conditions, so this device is installed in a company, for example, and the phone number of the employee of the company is registered in the memory in advance. In other words, if an employee makes a business call to the company, he / she can contact the employee by making a call back to the employee from the device, and therefore the call charge based on the employee's call Can be properly borne by the company. Also, if abandonment of the caller is detected after a match between the calling number and the phone number in the memory is detected, a ring tone is sounded and an automatic call is sent to the caller upon detection of an incoming call response operation. Thus, the user of the apparatus and the caller can be reliably connected to the line. When a match between the received calling number and the telephone number in the memory is detected, a call is automatically sent to the caller. When a response from the caller is detected in response to the automatic call, a signal via the caller's line is sent. Even if the user of this device cannot return to the caller due to absence, the message can be automatically sent to the caller and the message of the responded caller can be recorded. Employees can contact the company without incurring call charges. In addition, after the caller abandons outgoing call after detecting the coincidence between the received calling number and the telephone number in the memory, the caller is automatically sent to the caller side, and the device side responds to the automatic call before detecting the call operation. When detected, the signal from the caller is recorded, so that the message of the caller can be accurately recorded.
