[Problems to be Solved by the Invention] All of these functions are functions that encourage quick calling and receiving with fewer operations. However, there is no function that allows speed dialing with fewer buttons while maintaining quick operation for both internal and external calls, even when the other party is busy or not responding. For example, if a person's destination is a certain department in the company A (extension), another department B (extension), a claim office (external line), or home (external line), the speed dial button required is 4. It is individual. Moreover, even if the caller makes a call, the caller must select and operate the speed dial button to be pressed until the caller is found. In addition, if a company's phone number has multiple numbers below the main number, during busy hours, the company may search for an empty subscriber line and call back one by one. There are many uses for shifting and dialing repeatedly. It would be extremely convenient if a speed dial shift calling function with simple operations could be provided for such applications.

[0004] The present invention has been made to solve this problem, and is capable of quickly receiving a call to the intended party, and in the case of a call being busy or absent/busy, the operation of re-dialing to another telephone number is carried out in a single operation. The purpose is to realize a more convenient speed dial function with fewer function buttons.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a button telephone with a speed dial button that allows a combination of a plurality of internal and external phone numbers to be registered, and a button that accommodates a plurality of button telephones. The telephone main device includes a storage unit that stores the registration number, a control unit including a microprocessor, and an internal/external system that corresponds to a plurality of pre-registered telephone numbers when repeatedly pressing the speed dial button on the extension telephone. In order to sequentially call subscriber telephones of the line, in response to pressing of a speed dial button, the telephone number of the internal and external lines read from the storage unit is sequentially sent to the control unit to prompt the caller to make a call. It becomes.

[0006]

[Operation] With the above-described configuration, the present invention allows you to check whether the next extension to be called is busy or not by operating a single speed dial button, and if it is not busy, call the original party directly. If you can call, but the caller is busy or absent (no answer), by pressing the same extension button repeatedly, you can quickly search for and select another extension that is not busy, prompting a substitute to answer the call, and waiting for the caller. can minimize time.

Hereinafter, the operation of making a call from a key telephone to a series of speed dial numbers according to the present invention will be explained based on FIGS. 1 and 2 and along FIG. 3.

First, before the operation of making a call from the key telephone A102 to another extension key telephone or another subscriber's telephone, when the key telephone A102 is in an inactive state, the LED display of the speed dial button A202 is changed to the speed dial button A20.
Displays whether or not it is possible to make a speed dial call to the first subscriber in registration order among the multiple subscriber phone numbers registered in 2. (If it is not possible, the light will light red; if it is possible, it will light red.) lights out,
However, if the other party is using an outside line, the message may not be displayed.) When the status of the extension phone at the top of the registration order indicates that calls cannot be made, pressing speed dial button A202 will call LE.
The D display is sent to the storage unit 111 via the dial call management unit 109.
The possibility of making a speed dial call to the next registered subscriber is displayed with reference to . Thereafter, a similar operation is performed to search for an abbreviated number (LED off) for a subscriber that can be called, and when found, an off-hook operation (pick up the handset 208) or press the speaker button 207. Thereafter, when the speed dial button A202 is pressed, a call/call to the subscriber's telephone is started.

If there is a response to this call, the call will proceed, but if there is no response, the button telephone A10

If left as is at that time, the main device control unit 108 refers to the memory in the storage unit 111 through the dial call management unit and transmits a call command for the next registered subscriber number to the telephone control unit 115 through the same route. As a result, a call is made to the other subscriber. On the other hand, if the on-hook operation (or the speaker button is pressed again) is performed at that time, the above speed dial button calling sequence is completed and the system returns to the initial state.

If the other party does not respond to the call because he or she is absent, the speed dial button 202 is pressed again to make a call to the next registered subscriber. When this button is pressed, the dial call management unit via the main device control unit 108 refers to the storage unit 111, and the LED of the speed dial button A202 displays the status of whether or not the next subscriber number call can be made, and the next registration is continued. Initiate a subscriber call.

[0016] Even if there is a response and the call progresses and the call ends, if you wish to make a call to the next registered subscriber, you can do so by pressing the speed dial button A202 again in the same manner as above. . At this time as well, after displaying whether or not abbreviated number dialing to the next registered subscriber is possible or not, a call to the next registered subscriber is started.

The above operation is completed by a normal on-hook operation or by pressing the speaker button, and the button telephone A102 returns to its initial non-operating state.

The LCD display 209 displays the contents of the LED status display of the speed dial button A202.
It is extracted from the internal ROM and displayed in detail using characters. Further, speed dial button B203 or speed dial button C204 also functions in exactly the same way as speed dial button A202.
