Abstract

PURPOSE: A receiver communication method of a telephone is provided to enable a receiver to select desired incoming calls in case many users use a telephone in common and permit a guide to receive a call and send a receiver a message in the case of receiver's absence. CONSTITUTION: If a ring signal is inputted through a telephone line(22), a microprocessor forms a loop(23). In a state that a password of a receiver telephone number is not outputted(24), if a state is turned in a hook off state(25), the microprocessor outputs a telephone line signal to a speaker phone circuit to intercept the ring signal, and performs communication between a transmitter and a receiver(26). If a password of a receiver telephone number is outputted, the microprocessor confirms stored passwords(27), and reads voice information stored in a voice memory for outputting as a voice(28,29). If a call is not received during a voice output(30), the microprocessor delivers a receiver absent message(31), and delivers a message asking whether a guide is necessary(32). If the transmitter wants the guide(33), a communication path is connected with the guide(34). If the transmitter does not want the guide, the microprocessor intercepts a signal for forming a speaker phone communication path(35). If a call is received, the microprocessor requests an input of a password(36). If the password of the receiver is in accord with the password of the transmitter(37), the microprocessor performs communication between the transmitter and the receiver through the telephone line(38). If the passwords are in discord with each other, the microprocessor delivers a password discord message(39).

Description

A receiver calling method of telephone

The present invention relates to a method for calling a called party of a telephone, and more particularly, when many people share a telephone together in an office or the like, only a desired called party can be selected to make a call. It relates to a method of calling a receiver of a telephone to receive and deliver a message.

Nowadays, due to the development of information and communication, it is well known that an individual telephone is installed in an office or a laboratory to handle all communication tasks.

In addition, telephones used in offices and laboratories are commonly used in a state where several lines are opened, and one ring signal is simultaneously generated on a plurality of telephones, so that a call may be received even if it is not a call made to oneself.

In addition, if the location of the caller and the person to be replaced is far from each other, it is not common to communicate directly, but to go through a few more people so that the caller is notified or is not known.

Therefore, in order to solve the above-mentioned conventional problems, all telephones of the office are connected to one exchange so that each telephone can be given a unique code and can quickly notify that the call has been received through this number.

However, the caller's call method of the conventional telephone using the exchanger has the disadvantage of adding the facility cost according to the use of the exchanger, and of course, the wiring becomes complicated because all the telephones have to be withdrawn to each seat through the exchanger. However, the number of wires that can be connected to a single exchange is limited, so it is inconvenient to use in a large office because an additional exchange is required to connect too many wires.

Accordingly, the present invention provides a method for calling a called party on one telephone so that many people can use only the desired called party to make a call when they share a telephone, and the guide can receive a call and deliver a message only when there is no called party. For that purpose.

In order to achieve the above object, the caller's call method of the present invention provides several times the caller to receive a call when the caller sends the password together with the phone number when the caller makes a call and receives the call during the guide. Enter the password so that the call is made only if it matches, otherwise the call is sent to the receptionist with a message that you are not in place, so you can answer the call without telling the caller to change who you are. It allows you to speak exactly with the person you want.

Hereinafter, the present invention will be described in detail according to an embodiment.

1 shows an overall configuration according to an embodiment of the present invention,

A ring detection circuit 2 for detecting a ring signal (call signal) from the telephone line 1,

A line interface unit 3 for forming a DC current loop of the telephone line 1 in response to a line control signal to match the connection with the telephone apparatus;

A line of the line interface unit 3 connected to the line interface unit 3 and driven in response to a speaker phone control signal to transmit an electrical signal from an external microphone (transmitter) 5 to the line interface unit 3. A speaker phone circuit 4 for outputting a signal to the speaker (receiver) 6;

Outputting the signal formed by the speaker phone call in response to the output of the ring detection circuit 2 to the line interface unit 3 and the speaker phone circuit 4 or in response to the input of a busy tone; A called-party microprocessor (7) for blocking a signal formed by the speaker phone call output to the line interface unit (3) and the speaker phone circuit (4) to restore the phone call path;

A display / control unit 9 for visually displaying display information output from the microprocessor 7 while transmitting a control signal of the user through the key input unit 8 to the microprocessor 7 above;

A tone detector 10 for detecting busy tone from the telephone line 1 and supplying the busy tone to the microprocessor 7,

A nonvolatile memory 11 for storing passwords of numbers corresponding to a unique number of a telephone under the control of the microprocessor 7,

Voice memory 12 that stores and outputs a voice message, such as "Make a call, Mr.", including a person's name of the seat where the phone corresponding to the password is located.

The called party calling method of the telephone of the present invention configured as described above is to allow a plurality of telephones connected in parallel with one telephone number as a representative number to make a call through any telephone or outside.

The microprocessor 7 located in each telephone reads the output of the ring detection circuit 2 to confirm the input of the ring signal (step 21).

As a result of the check, if the ring signal is normally input through the telephone line 1 (step 22), the microprocessor 7 which has received information about the ring signal through the ring detection circuit 2 transmits the signal formed by the speaker phone call to the line. Matching while outputting to the interface unit 3 causes a loop for a call to be formed (step 23).

In the state that the above loop is formed, the caller picks up the microphone 5 and the speaker 6 of the handset while the caller does not output the password of the numbers corresponding to the unique number of the telephone to be called (step 24). If it is in the state (step 25), the microprocessor (7) recognizes this and outputs the telephone line signal to the speaker phone circuit (4) so that the ring signal is blocked so that the caller and the called party go through the telephone line (1). The call can be made (step 26).

On the other hand, if the caller outputs the password of the number corresponding to the unique number of the telephone to be called in step 24, the microprocessor (7) receiving the input checks with the password stored in the nonvolatile memory (11) Determine whether the call is a search for (step 27).

Next, the voice information stored in the voice memory 12 is read out (step 28), and the voice information is output several times in the same manner as the "call Mr. **" (step 29).

If no handset is picked up by anybody during voice announcements (step 30), the microprocessor 7 determines that the party is out and sends a message to the caller indicating that the called party is not present (step 31), The receptionist sends a message asking if it is necessary (step 32).

If the caller wants to change the attendant (step 33), he connects the call to the attendant (step 34), while if the caller does not want the attendant, the line interface to end the call and restore the speakerphone channel. The formed signal is cut off by the speaker phone call output to the unit 3 and the speaker phone circuit 4 (step 35).

If someone raises the handset's microphone 5 and speaker 6 to the hooked-off state before the voice guidance is output several times in step 30, the microprocessor 7 recognizes this and requires a password to be input. (Step 36).

If the password entered by the called party is the same as the password entered by the caller (step 37), the telephone line signal is output to the speaker phone circuit 4 so that a ring signal is cut off so that the caller and the called party enter the telephone line 1 through the telephone line 1. Allow the call to be made (step 38).

If the password is not the same in step 36, a message indicating that the password is incorrect is sent back to step 32, and the guide asks whether a guide is needed (step 39).

Therefore, according to the method of the called party of the telephone of the present invention, when a caller sends a password specifying a called party together with a phone number when the caller makes a call, the called party receives the call several times and enters a password while receiving the call during the guidance. Make sure that the call is made only when there is a match, and that you are in a call with the receptionist with the message that you are not available elsewhere, so that you can answer the call without answering the caller or telling the caller to change who you are. It is to make the call correctly.

Claims (1)

The microprocessor 7 which receives the output of the ring detection circuit 2, checks the input of the ring signal, and receives the information on the normally input state, outputs the signal formed by the speaker phone call to the line interface unit 3. While matching, so that a loop for a call is formed, and the microphone 5 and the speaker 6 of the handset are brought into a hook-off state, the receiver recognizes this and outputs the telephone line signal to the speaker phone circuit 4. In the caller's call method of the telephone which allows the caller and the called party to make a call through the telephone line 1 by blocking the ring signal, When the caller outputs the passwords of the numbers corresponding to the unique numbers of the telephones to be called, the microprocessor 7 which receives them is compared with the passwords of the nonvolatile memory 11 to determine who is calling. To do that, Reading the voice information stored in the voice memory 12, and outputting the voice information several times, such as "Make a call, Mr. **"; If the handset does not pick up the handset while the voice is output several times, it is determined that the party has gone out and sends a message notifying the caller that the called party is not in place, and then sending a message asking if the receptionist is necessary; If the caller wants to change the attendant, direct the attendant to the line, and if not, end the call; If the handset is lifted off before the voice prompt is output several times, requesting the microprocessor 7 to input a password; If the password entered by the called party is the same as the password entered by the caller, allowing the caller and the called party to make a call through the telephone line 1; If the password is not the same, the caller of the telephone, characterized in that carried out by the steps of asking the receptionist after sending a message that the password is wrong.
