JPS61142843A - Call-back system of telephone - Google Patents

Abstract

PURPOSE:To attain the automatic call-back of an originating subscriber after calling by using a means which reads the telephone number of the originating subscriber and stores it temporarily in a memory and a means which transmits automatically said telephone number. CONSTITUTION:A telephone main body 2 contains a display device 3, an originating telephone number circuit 4 containing a memory and an automatic originating circuit 5 which calls an originating subscriber with operation of a call-back key B. A voice generating circuit 6 produces a request for a collect call and the voices of the originating number. A number circuit 4 reads the originating telephone number and stores it temporarily in a memory and also displays it on the display device 3. When the key B is operated after calling, the originating subscriber displayed on the device 3 is called out automatically by the circuit 5. The circuit 6 is actuated with operation of a collect call key C and gives a collect call to the station side through synthesization of voices via a collect call circuit.

Description

[Detailed Description of the Invention] The invention is a callback system in a telephone that reads the caller's telephone number from a third party during a call, temporarily stores it in memory, and automatically calls the caller to the Tsutsutsusa. Regarding the system.

In the information society, the use of telephones has expanded, and there are many cases where the telephone is busy, and people feel safe calling again after a while. An automatic calling function has been adopted that repeatedly calls the other party, but it is difficult to put it into practice because one party may leave their seat when the other party gets through. In addition, information providers and customers have a strong need for collect calls, which is a receiving fee payment system, and are looking forward to the emergence of a cold bank system that also has the automation of collect calls.The present invention meets this demand. This has been devised and will be explained in detail below based on the drawings.

Telephone unit (2) that occupies two lines from the main switch (1)
is a caller telephone number circuit (4) having a display (3) and memory, an automatic dialing circuit t5) that calls the caller telephone number by operating the callback key (B), and a collect call and caller telephone number circuit. and a sound generation circuit (6) that generates the sound. The number circuit (4) deciphers the caller's code, temporarily stores it in memory, and displays it on the display (
3), and if the caller uses an analog telephone, it will be equipped with a special modem that emits a signal tone.

During a call, one line is used, and the signal for such telephone number is obtained by the other line. A correspondence list may be stored in a separate memory so that the name of the caller appears on the display (3) at the same time depending on the caller's telephone number. The automatic calling circuit (5) is the same as the well-known repeated automatic calling circuit, and each time the caller automatically calls the destination of the telephone number stored in the memory without having to press a numeric key. The voice generation circuit (6) is a chip circuit that generates synthetic onomatopoeic sounds such as "Please make a collect call. The other party's phone number is...", and the phone number, which varies depending on the caller, is a number from 0 to 9. It is obtained by combining the audio signals up to.

Next, the effect will be explained. During a call, a caller's telephone number from a third party is read in a number circuit (4), temporarily stored in a memory, and displayed on a display (3). To memorize multiple telephone numbers and display the name of the caller as needed. After the call, confirm the telephone number and name displayed on the display (3), operate the callback key (B), and automatically call the caller using the automatic calling circuit (5). When there is no response, a cancel key (not shown) is pressed to call the next caller. To use the collect call function in conjunction with this callback function, press the callback key (B
) and operate the collect call key (C) to convert the caller's telephone number temporarily stored in memory into a synthetic onomatopoeic sound, which is generated by this sound generation circuit (6) along with other synthetic sounds, and then Inform the central office of your intention to make a collect call through the connected collect call line. If the caller accepts the collect call request from the central office, the two lines will be connected.

As described above, the present invention is capable of reading the caller's telephone number, temporarily storing it in memory and displaying it, and making it possible for the automatic calling circuit (5) to immediately call back the caller. (6) and the automatic dialing circuit (5) make it possible to make information and collect calls, thereby significantly improving the functionality of the telephone, which is an advanced information metric.

[Brief explanation of drawings]

The drawings show an example of the implementation of the present invention, and FIG. 1 is an explanatory diagram of a case where two lines are used in a mobile telephone, and FIG. 2 is an explanatory diagram of a telephone set.

Claims (2)

[Claims] (1) During a call using one line, the caller's phone number from a third party is determined through the other line, temporarily stored in memory, this number is displayed on the phone, and a call is made after the call ends. A callback system in a telephone that transmits a pre-memorized number to an automatic dialing circuit and calls the caller by operating the back key. (2) During a call, the caller's phone number from a third party is read and memorized and displayed, and after the call ends, the callback key and collect call key are operated to request a collect call and send the caller's phone number to the voice generator. A callback system in a telephone device that first transmits information to the exchange, etc. via a telephone, and then connects to the caller after receiving the caller's consent.
