Description

Dialing device for wired and wireless telephones {A DIALING APPARATUS IN TELEPHONE}

The present invention relates to a dialing device for a wired or wireless telephone, particularly when making a call to a place with a large amount of calls. A dialing device for a wired or wireless telephone, which makes a call repeatedly until the other party answers the call with one dialing input.

The primary purpose of landline or cordless telephones (hereinafter referred to as "wireless and cordless telephones") is to conduct a call.

In order to perform a call, the user usually dials the other party's telephone number, and as a result, a ringing bell rings on the other party's phone, and when the user picks up the handset, a call path is formed between each other to perform a call.

In the case of the above dialing, it is made by inputting a unique number designated for each telephone, that is, a telephone number.

However, after dialing to perform a call, when the other party is in a busy state, the designated type of call tone is transmitted to the calling party.

By listening to the call tone, the user is aware that the call is not performed in the current state.

Therefore, the general users attempt a call by dialing the other party's telephone number again after a certain time, and thus the call is performed when the call is made.

On the other hand, the phone number is usually made of a number of digits. The user must enter all of the corresponding numbers that make up the phone number for dialing.

This brings inconvenience to the user, and to solve this problem, conventional telephones are provided by implementing a 'redialing' function.

The redialing function is a function for automatically dialing a phone number previously input by one-touch input of a predetermined key as it is.

Its features make it easier for users to use.

On the other hand, when the other party wants to connect the call, where there is a relatively large amount of call, it is often difficult to connect the call. In this case, the user repeatedly performs dialing until the call is connected to the other party. At this time, the redialing function brings convenience to the user without having to input the phone number several times.

That is, if the other party continues to be in a busy state, the call is not connected until the other party's busy state ends. In this case, the user inevitably repeats the call until the other party ends the call. There is no choice but to do it.

Even in the case of using the redialing function described above, it is convenient to reduce the number of key inputs according to the telephone number input, but this also requires the user to continue inputting the corresponding key until the other party ends the busy state. Discomfort cannot be solved.

Accordingly, there has been a demand from a user who uses a conventional wired / wireless telephone that can continuously perform dialing even without performing a separate phone number or key input until a call connection is made with the other party.

In particular, as mentioned above, when a call attempt is made to a place where connection is relatively difficult due to a large amount of calls, such a function is further required.

However, conventional wired and wireless telephones do not implement such a function, which brings a lot of inconvenience to users.

Therefore, the purpose of the present invention is to use a wired or wireless telephone, especially when making a call to a place with a large amount of calls. The present invention provides a dialing device for a wired / wireless telephone that repeatedly makes a call until the other party answers the call with one dialing input.

In order to achieve this object, the present invention; A memory for storing dialed telephone numbers;

A telephone line switch for switching the hook switch; A call tone detection unit for detecting a call tone transmitted from an exchange of a telephone station connected through the telephone line switch when the state of the call counterpart phone is busy; A timer for counting a certain time; If there is a predetermined key input according to the detection of the busy tone after the dialing, if the result of the detection of the busy tone is output from the busy tone detection unit, the driving of the timer is controlled and the completion of the counting of the predetermined time according to the driving of the timer is performed. If so, it is characterized in that it further comprises a control unit for controlling the on / off hook switching of the hook switch, and repeatedly dialing the stored telephone number.
