Since this is an open matter, no full text was included.

1 is a circuit diagram of a telephone for carrying out the invention, and FIG. 2 is a flow chart according to the invention.

Claims (4)

A device for storing phone numbers and automatically dialing in the absence of a multifunction telephone, comprising: a ring detection circuit for detecting a ring signal from a trunk line, a voice signal at the time of call, and an electrical signal at the time of call. And a DTMF receiver which decodes each dialing signal from the other party received from the trunk line into binary data, and a trunk line, connected to the trunk line, and connecting the trunk line to the conversation circuit in response to a control signal. A pass control circuit for connecting a dialing signal to the DTMF receiver, a voice synthesis circuit for generating and supplying a predetermined voice message to the call circuit during operation, an indicator for displaying a telephone number, first, second and second A ring input in response to the first service key, having a key input circuit for dialing a telephone number, and having a memory; The memory is generated every time an output signal is input, the voice synthesis circuit is activated whenever the communication circuit is connected to a trunk line in response to the control signal, and the memory allocated to each dialing signal in the received order. Storing the data sequentially in the area, sequentially outputting the dialing signals stored in sequence to the indicator when the second Servisky is operated, and outputting the control signal in response to the operation of the third service key. A telephone number memory display and automatic dialing device for a multifunction telephone, characterized in that the multi-function telephone is configured to transmit a dialing signal corresponding to the telephone number selected during the display to the trunk line while being connected. In the absence of a telephone number gear display and automatic dialing method of a multifunction telephone using a voice synthesis circuit and a microprocessor for synthesizing and outputting a digital voice message, scanning a key input port to search whether a function key or display key is input. A ring signal detection step of searching for a function key input search process, whether a ring signal detection signal is detected when it is determined that an outgoing function key is input in the function key input search process, and a ring signal is detected in the ring signal detection process During the determination, the process of sending the missed message to form a call path and sending the missed message, the input dial signal storing process of storing the binary code of the DTMF input after sending the message in the internal memory, and the function key input searching process are displayed. When it is determined that the key is input, the address is issued according to the number of key input. A telephone dialing process for accessing and displaying a telephone number stored in an area corresponding to the address in the internal memory, and dialing the displayed telephone number by inputting a sending key. Display and auto dialing method. 3. The method of claim 2, wherein the dial signal storing step detects whether a DTMF signal is detected, blocks the call path when it is determined that the DTMF signal is not detected, and detects the DTMF signal. A phone number storing step of storing a dial digit of the input DTMF in an internal memory area, a dial end key detection searching step of searching whether a dial transmission end key has been detected after completion of the storing step, and ending the dialing. In the multi-function telephone, when the key detection search is determined to be non-detection, the process jumps to the DTMF detection search process, and when the detection is detected, the memory address allocation process is performed to incite the memory address. Dialing method. 4. The method of claim 3, wherein the dial transmission process includes a display key input search process for searching whether a display key has been input, and a read address is incresed when it is determined that the display input is performed in the display key input search process and accesses stored data in the address area. And a lead address allocation process for displaying the lead address, and searching for an input of the dial transmission key after assigning the lead address, and jumping to the display key input search process when the dispatch key is not input, and forming a call path when transmitting the transmitted telephone number. In the multi-function telephone characterized in that the display phone number transmission process made in the absence of the telephone number memory display and automatic dialing method. ※ Note: The disclosure is based on the initial application.
