As described above, the transfer telephone of the present invention automatically answers when there is an incoming call and connects the incoming call line to the audible signal receiving circuit. The registered dial code is sent to the transfer line, and the incoming call line is connected to the transfer line.

〔Example〕

Next, a transfer telephone according to the present invention will be explained with reference to the drawings.

FIG. 1 is a functional block diagram showing one embodiment of the present invention, and FIG. 2 is a flowchart showing an example of the main operation procedure of FIG.

In FIG. 1, the same components as those in FIG. 3 described in the prior art are given the same reference numerals and their explanations will be omitted.

In FIG. 1, a transfer telephone 1 includes telephone circuits 11, 20.
Handset 12. Changeover switch 13. Automatic response circuit 14.
Voice guidance circuit 15° Audible signal receiving circuit 16. Control circuit 1
7. Dial code registration circuit 18. It has an automatic dialing circuit 19° and a coupling circuit 21, accommodates two telephone lines, and connects one as the incoming call line 2 and the other as the transfer line 3 when switching to transfer.

When there is an incoming call from the incoming line 2, the automatic answering circuit 14 automatically sends a response signal to the calling party, and also sends a voice guidance circuit 15 to the sending line of the incoming line 2 and an audible signal to the receiving line. The receiving circuits 16 are connected to each other. The voice guidance circuit 15 is driven by the automatic response circuit 14, and can be configured to, for example, say [This is Abe. I'm away from home at the moment, but I'll transfer it to my office, so please wait for a while. ” is sent to the calling party. The audible signal receiving circuit 16 identifies the audible signal received from the called line 2 and notifies the control circuit 17 of the audible signal.

The audible signals received and identified from the called line 2 include pushbutton dialing (hereinafter PB) signals and busy tones transmitted by the exchange. The control circuit 17 indexes the outgoing dial code to be transferred from the dial code registration circuit 18 to the exchange based on the PB double signal received from the audible signal receiving circuit 16, and outputs it to the automatic dial outgoing circuit 19. 21 to connect the called line 2 and transfer line 3. The dial code registration circuit 18 registers and stores at least the dial code for speed dialing in addition to the dial code of the transfer destination.

Next, the operating procedure will be explained with reference to FIG. 2 and FIG. 1 together. As shown in FIG. 1, the changeover switch 13 is set to transfer due to absence.

When the automatic answering circuit 14 detects an incoming call on the called line 2, it automatically answers (step S1), sends a response signal to the calling party, and also causes the voice guidance circuit 15 to send a call on the called line 2. For example, ``This is Abe. I'm away at the moment, but if you would like to be transferred to someone outside the office, please press the button and dial 011.'' (Step S2) ), and connects the audible signal receiving circuit 16 to the receiving line and waits for reception of the PB double signal. Audible signal receiving circuit 1
6 receives the PB double signal (step S3) and dials code 01
1 When it is identified as an automatic transfer request (step S4), the control circuit 1
7 receives the dial code 011, searches the dial code registration circuit 18, and enters the dial code of the automatic transfer destination (for example, 0
3-213-4567) is read out (step S5) and transferred to the automatic dialing circuit 19. When the automatic dialing circuit 19 receives the dial code 03-213-4567, it activates the transfer line 3 via the telephone circuit 20, and automatically dials the dial code 03-213-4567 (step S6).
) to ring the called telephone. When the called telephone answers, the control circuit 17 that receives the response signal via the telephone circuit 20 (step S7) drives the coupling circuit 21 to couple the telephone circuit 20 to the automatic answering circuit 14, and connects it to the transfer line 3. A communication path is established with the call line 2 (step S8). Restoration of the telephone due to call termination is carried out by the audible signal receiving circuit 16 receiving and identifying a busy signal sent by the telephone line 2 or 3 due to a decrease in current or the exchange being restored.

In step S4, the control circuit 17 inputs, for example, the speed dial code *
When 01 is received, the dialing code registration circuit 18 reads out the sending dialing code 03-222-3333, which has been registered in advance for the abbreviated dialing code *01 (step S
9) and continues with the automatic calling procedure of step S6.

In the above embodiment, the dial code registration circuit is provided in common for both automatic transfer and speed dialing, but the automatic forwarding destination dial code registration circuit and the speed dial code registration circuit may be separated, and various types of dial code registration circuits may be used. Since a single microprocessor utilizes many programs and data to perform the circuit, the block mechanism is not limited to the above description.

In the above embodiment, automatic transfer was explained on the assumption that the caller made the call using the pushbutton dial. Considering that the call is being made from a telephone with a dial, the voice guidance is ``Please wait for a while as the transfer will be forwarded to your destination.'' If a speed dial code is received by the end of the voice guidance, the speed dial code setting will be applied. The automatic dialing procedure to the caller starts, and if the PB double signal is not received at the end of the voice guidance, the above step S5 is automatically performed.
The next step is to send the dialing code to the forwarding destination.

Furthermore, regardless of the presence or absence of the voice guidance circuit described above, automatic transfer may be started after waiting for a predetermined time limit for receiving the first PB signal.

Furthermore, by expanding the message content of voice guidance, it is possible to expand the processing to include not only transfer processing but also other functional processing.

〔Effect of the invention〕

As explained above, according to the transfer telephone of the present invention, when there is an incoming call on one of the two telephone lines, it automatically answers the call, receives the FB double signal from the caller, and registers it in advance. The system reads the dialing code and automatically sends the dialing code to the other forwarding line, allowing a subscriber who has set up call forwarding to call his or her own telephone and receive speed dialing service. It is possible to improve the operational service by being able to call the called party even if the user remembers the information.
