Abstract

PURPOSE:To improve possibility to take connection with an opposite by previously registering plural telephone numbers in order and calling the subsequent number when the number which has initially been rung up does not respond. CONSTITUTION:When detection means 11 and 20 detect no response with respect to call, an automatic call means 17 automatically calls the telephone set of the other telephone numbers stored in a storage means 13. When the memory 13 for registering plural telephone numbers and a function for recognizing that the opposite does not respond and for automatically calling the other numbers are given, possibility to communication with the opposite can be improved by executing connection with the previously registered number when the opposite is absent.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone having a telephone number storage function and an automatic calling function.

[Prior Art] Conventional multi-function telephones store the telephone number of the called party that has been called several times in memory, and when the dialing button is pressed and input, the previous call stored in the memory is recalled. Some devices have a redial function that automatically calls the same phone that was used.

[Problems to be solved by the invention] However, such conventional telephones have the disadvantage that if the other party is absent for a long time, there is no response no matter how many times you redial, and the call cannot be connected to the other party. there were.

[Means for Solving the Problems] The present invention has been made for the purpose of solving the above-mentioned problems, and includes the following configuration as a means for solving the above-mentioned problems.

That is, a storage means for storing at least two telephone numbers, a detection means for detecting whether the called party has responded within a predetermined time, and when the detection means detects no response, the telephone number stored in the storage means is stored. and automatic calling means for automatically calling the telephone number.

[Operation] In the above configuration, when the detection means detects that there is no response to a call made by the automatic calling means, the automatic calling means automatically calls the other telephone number stored in the storage means.

In this way, by having a memory for registering multiple phone numbers and a function that recognizes when the other party is not answering and automatically calls another number, if the other party is not available, it can be registered in advance. By connecting to the given number, you can talk to the other party.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment according to the present invention, in which reference numeral 11 is a control unit that controls the entire telephone of this embodiment according to the program shown in FIG. 2, for example, which is stored in a ROM 12; In addition to the above-mentioned program, there is a ROM for storing parameters used in this embodiment, 13 a memory for storing a plurality of call destination telephone numbers, etc., and 14 a display section for displaying and outputting telephone numbers, predetermined messages, etc. 15 is a key manual interface that controls the interface with the keyboard 16; 16 is a keyboard consisting of a numeric keypad 16a for inputting a telephone number; 17 is a telephone number inputted from the numeric keypad 16a via a line interface 19;
or an auto-calling unit ACU that sends a telephone number signal corresponding to the telephone number information read from the memory 13 to the line; 18 is a handset; 19 is a line interface that controls the interface with the connecting line; 2° is a timer circuit; 25 is an internal bus that connects the control unit 11 and other components. Further, 30 is a telephone line network to which the telephone is connected.

The telephone number dial control of this embodiment having the above configuration will be explained below with reference to the flowchart of FIG. It should be noted that the process of receiving a call from the line and the response process to the call is well known, so a description thereof will be omitted.

First, in step Sl, initialize the desired number of phone numbers from 1st to nth (for example, n=3).
Input from the numeric keypad 16a of the keyboard 16 to memory 1
Register for 3. This input is performed while checking on the display section 14. These telephone numbers are sequentially registered in the memory 13 in the order in which they were input. Then, in step S2, the handset 18 is taken off-hook and waits for a call request to be made.

When off-hook is detected, the process proceeds from step S2 to step S.
Step 3 instructs the line interface 19 to generate a DC loop in the connected telephone line and issue a call request. Then, in step S4, the ACU 17 is activated to send a telephone number signal to the connection line in accordance with the called party's telephone number entered manually from the numeric keypad 16a. The telephone line network 30 selects and calls the telephone specified by this telephone number signal. Therefore, in step S5, the timer circuit 20 is activated to activate the timer for a predetermined period of time. In this embodiment, approximately 10 ring tone output times are set. In subsequent steps S6 and S7, it is monitored whether the other party (called party) has responded before timeout.

If the other party responds within the predetermined time, the process advances from step S6 to step SIO, where the normal call state is established and step S
Wait until off-hook is detected in ll or the other party releases the line and the call ends, and when the call ends, in step S12 the DC loop to the line is released to restore the line, and the process returns to step S2. .

On the other hand, if the other party does not respond within a predetermined time, the process proceeds from step S7 to step S20, where it is checked whether there is an uncalled registered telephone number in the memory 13, and if there is an uncalled registered telephone number, The process proceeds to step S21, where the first registered telephone number among the uncalled registration numbers is read out, and the process returns to step S3, where a call is made to the telephone set corresponding to the read number.

Initially, the first registered telephone number information is read out and a call is made. If the other party does not respond again, the process proceeds from step S20 to step S21 again, and a call is made to the second registered number. This is repeated n times (up to 3 times in this case) for each registered number.

Whether there is a next candidate for the registration number is determined by the first item in the memory 13.
Just write the phone number that has already been called before the th number registration area. Similarly, if the last registered telephone number is also stored, the next time a telephone number to be registered is added, additional registration can be done quickly.

Note that when the call processing to all registered telephone numbers is completed, the process returns to step S2, the redial processing is completed, and preparations are made for the next call request.

[Effects of the Invention] As explained above, according to the present invention, multiple telephone numbers are registered in advance in order, and if there is no response at the first number, the user can contact the other party by dialing the next number. This has the effect of increasing the possibility of obtaining .
