Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a speed dial system that registers speed dials in a plurality of dial number storage areas according to predetermined dial key operations, and reads the speed dials to perform automatic dialing. Relating to feature telephones.

[Prior art]

In conventional answering machines, when setting the answering machine mode, if it is obvious that the caller is away from home, the caller is required to indicate the outgoing telephone number in a response message and call the caller back. However, this is undesirable because the calling party has to bear the charges for two calls, and if the subscriber is on the move, there may be no response after all, and in this case, the answering machine It was extremely inconvenient to have to call someone else's office and record a message about the matter, or find a time to call someone else when they were out of the office.

On the other hand, there are forwarding phones that transfer calls directly.
The problem was that the equipment cost was extremely high, as it required two central office lines.

[Summary of the Invention] The present invention focuses on the fact that a functional telephone having a speed dial circuit with a memory function as described above has recently been proposed. After registering the forwarding destination phone number in the area in advance and recording the message for each incoming call in answering machine mode, the answering machine releases the central office line, reacquires the central office line, and sends the corresponding address data. By performing automatic dialing in response to the output of the forwarding destination phone number read from a specific dial number storage area, the speed dialing means normally used for general speed dialing can be used for forwarding when in answering machine mode. The present invention provides an answering machine that eliminates the inconvenience of having to call back, etc. on the caller's side, and allows efficient use of lines and equipment. Hereinafter, the present invention will be explained in detail using Examples.

〔Example〕

FIG. 1 is a block diagram showing one embodiment of the present invention. In the figure, 1 is a telephone circuit, which includes a telephone circuit, a handset circuit, a bell circuit, etc.
It includes the usual circuits attached to regular telephones, except for the following dial-related circuits. 2 is a dial signal generation circuit which generates a DP or PB dial signal. This is constituted by, for example, a commercially available dial LSI (dial IC) with a memory function, and corresponds to the dial according to the normal dial input from the dial key circuit 3 having a push type or rotary type dial operation panel. Generates a signal and connects it to the station line terminal L
In addition to sending out a telephone number stored in advance in the memory area, speed dial input can be read out as address data and output. To write to the memory, follow the prescribed operation procedure of the dial keys. For example, as shown in Figure 2 a, after turning on the hook, key-in the desired destination phone number on the specific function key □*, and finally For example, this can be done by key-inputting an arbitrary number from a memory address of 20 areas from "00" to "19". similarly
In the case of a call to an outside line from within the PBX, registration is performed by storing an outside line calling number of, for example, "0" as shown in FIG. Further, readout is performed, for example, by pressing a specific function key □# and then inputting a memory address as a speed dial after on-hook, as shown in FIG. A dialing signal is generated. In the case of making an outside line call, for example, the user inputs the memory number, confirms the dial tone, and then inputs the □# key, as shown in FIG. 5B.

On the other hand, 4 is a control circuit equipped with a well-known CPU or microprocessor unit, etc., and when the answering mode is set by the operation switch provided in the operation and display circuit 5, the answering operation is performed according to a predetermined program. Therefore, next, this operation will be explained using the flowchart shown in FIG.

When the incoming call detection circuit 6 detects an incoming call (step 100), the control circuit 4 operates the line relay RL (step 101). As a result, the contact rl is switched from the state where it is connected to the telephone circuit 1 side shown in the figure to the answering machine section side that includes the hybrid amplifier 7. Next, the control circuit 4 switches the analog switch
SW1 is turned on (step 102), and the recording/reproducing circuit 8, specifically the tape deck, is controlled to reproduce the response message previously recorded on the cassette tape. The response message is sent from the playback head through amplifier 9 and hybrid amplifier 7 to local terminal L.
(step 103). In this case, the response message may be a message informing the subscriber that the system is in place to transmit the message recorded by automatic transfer to the subscriber after a while. When the response message is completed (step 104), the control circuit 4 turns off the analog switch SW1 (step 105), turns on the analog switch SW2 instead (step 106), and controls the recording/playback circuit 8 again to perform a predetermined operation. A message from the caller is recorded in the tape area of the caller. The voice signal sent from the calling party via the office line terminal L is transmitted to the recording head via the hybrid amplifier 7 and the amplifier 10, and is recorded (step 107). After the termination (step 108), the control circuit 4 restores the line relay RL and immediately opens the central office line (step 108).
109). At the end of this message, the line disconnection detection circuit 1 detects a click sound accompanying the caller's on-hook.
1, or by detecting that no audio input has continued for a predetermined period of time using an audio switch.
In addition, if the click sound cannot be detected for some reason, or if a prank call is taken into consideration, the central office line is forcibly opened when the timer measures that a predetermined period of time has elapsed. After the line relay RL is restored, a timer is set (step 110), and after a predetermined period of time has elapsed, the exchange side is completely restored (step 111).
operates the on-foot relay RH (step
112). This on-hook relay RH serves as a relay for on-hook dialing, and this operation closes the contact rh connected in parallel to the hook switch HS of the telephone circuit 1, resulting in a state similar to that of off-hook. Next, the control circuit 4 sends a control signal to the abbreviated dial number data generation circuit 12, and outputs specific address data corresponding to a predetermined memory number of the aforementioned dial signal generation circuit 2, for example "19".
to occur. Since the forwarding destination telephone number has been registered in advance at address 19 using the operating procedure explained using FIG. reads out the forwarding destination telephone number and sends it to the curved terminal L, whereupon automatic dialing is performed (step 113). Next, the control circuit 4 operates the line relay RL again to switch and connect the office line to the answering machine unit including the recording/reproducing circuit 8 (step 114). On-foot relay
RH is restored and telephone circuit 1 is restored (step 115). When the called party answers at the transfer destination, the control circuit 4 detects this by the called party response circuit 14 (step 116), turns on the analog switch SW1 (step 117), and controls the recording/playback circuit 8. A transfer message indicating that the recorded business message will be transferred is reproduced and sent out (step 118), and after completion (step 119), the recording and playback circuit 8 is controlled again to reproduce and send out the business message (step 120). Note that the forwarded message may be omitted or may be a specific audible signal.
Further, although omitted in FIG. 4, if the transfer destination is busy, the central office line may be released and the process may be repeated from step 112 after a certain waiting time. After sending the business message (step 121), control circuit 4 restores line relay RL (step 121).
122) After turning off the analog switch SW1 (step 123), the recording/reproducing circuit 8 is controlled to perform recovery operations such as locating the beginning of the response message tape in preparation for the next incoming call (step 124).

In this way, by using the dialing signal generating circuit normally used for speed dialing, it is possible to automatically dial a pre-registered forwarding destination in the answering machine mode and to forward a business message. Incidentally, although omitted in FIG. 4, if the caller goes on-hook without recording the business message, the central office line is immediately opened and the process shifts to restoring the recording/reproducing circuit 8.

In addition, in the embodiment described above, the telephone circuit 1
Although the contact rl of the line relay RL is used to switch and connect the side and the answering machine unit side, it is also possible to make a branch connection between the two and to use the line relay RL as a closing relay exclusively for the answering machine unit. In this case, the dial signal from the dial signal generating circuit 2 may be separated only in the case of a transfer call and sent from the answering machine section.

Furthermore, the line relay RL is restored when the recording of the message is finished, and the on-hook relay RH is operated again after re-acquiring the office line to connect the office line to the answering machine, but the recording of the message is finished. Afterwards, without restoring the line relay RL, the central office line may be opened for a certain period of time using other means on the answering machine side, and after the central office line is recaptured, a dial signal may be sent from the answering machine side.

Further, although a recording tape is used as a means for recording and reproducing each message, it goes without saying that a method may also be used in which the audio signal is stored in a memory as a digital signal and reproduced by voice synthesis.

〔Effect of the invention〕

As explained above, according to the present invention, an answering machine is built into a functional telephone equipped with a speed dial circuit with a memory function, and a part of the memory area for speed dialing is used to automatically dial a forwarding destination. This has the effect of eliminating the inconvenience of having to call back, etc. on the calling party's side, and also enabling efficient use of lines and equipment.

That is, specifically, there are the following effects.

(a) Since the speed dial line with memory function of a multi-function telephone is also used, there is no need for an automatic dial memory dedicated to the forwarding destination call number.

(b) Registration of the forwarding destination phone number can be done by the normal speed dial registration operation, so there is no need for new, unfamiliar operations.

(c) No new configuration means or operating program is required for forwarding phone number registration.

(d) A low-cost integrated telephone can be obtained since no new parts are required.

(e) The memory area where the forwarding destination phone number is stored is originally the speed dial memory area of the multi-function telephone, so if the user does not use the forwarding destination call function, this area can be used as the speed dial number area. Yes, and the speed dial function of the multifunction phone will not be affected in any way.

(f) Furthermore, in the present invention, since the dial IC in the telephone has a speed dial memory, there is no need to use the station's speed dial service. Therefore, there is no need for the subscriber to resubscribe to a new PB line, there is no need for the subscriber to receive a speed dial service, and the subscriber is not forced to spend extra money. Furthermore, since there is no need for a telephone for PB dialing, there is no need to choose the type of telephone, and since the dial IC for speed dialing is inexpensive, it is possible to reduce the cost of the device.
