BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to button telephone equipment.

0002

BACKGROUND OF THE INVENTION In recent years, there are many functions that have been implemented in key telephone devices, such as hunting calls and shift calls. There is a function that allows you to have one person answer the call.

[0003] The method of making a hunting call is to register a group of extension telephones into several "hunting groups" in advance in the system settings of the key telephone device.
This is achieved by dialing a special hunting group number at the time of making a call and making a call to an extension phone that can receive calls within the corresponding hunting group,
Also, like normal extension calling, when one extension number within the hunting group is dialed, other extensions within the hunting group are called only when the corresponding extension is unresponsive (busy, etc.).

[0004] These methods assume that there is no need for a specific person to respond from the beginning, and in most cases, someone in the group answers the incoming call and then transfers the call to the intended person or sends a message. There has to be a next one. Those who call must also be prepared to wait a long time until they can be reached.

[0005] Another method is shift calling, in which when a call is made to a certain extension and the other party is busy or does not answer, an adjacent number with the same high-order digits but a different last digit is called. This function allows you to change the call destination by dialing only the last digit of the extension number.

[0006] This method makes it possible to first make a call to the intended destination and, if it is busy, to change the call to another adjacent extension, but it has the following two problems. This means that it can only be used between extensions waiting for an adjacent number, and that you must confirm the new telephone number and know the additional dial number before using it. Furthermore, if the destination becomes busy, a shift call will be made to another extension again, and a quicker response to the call cannot be expected than in the case of the hunting call.

[0007]

[Problems to be Solved by the Invention] The conventional method described above is an efficient button telephone that is capable of quickly receiving a call to the intended party, and having a substitute answer the call quickly if the person is busy or absent. There are advantages and disadvantages to the incoming call function.
It wasn't perfect. That is, in the case of a hunting call, there is a drawback that it takes time to relay the call because the original destination does not directly respond to the call. On the other hand, for shift calls, the number of extensions that can be used is limited, and the last number of the shift destination must be confirmed in advance.

The present invention has been made to solve this problem, and an object of the present invention is to provide a button telephone device that is easier to use and has a function that allows efficient incoming call response with natural operation.

[0009]

[Means for Solving the Problems] In order to achieve the above object, the present invention is capable of registering a plurality of extension numbers in a key telephone device, and is provided with an extension button that displays the device status of the registered extension.
a storage section for storing a plurality of extension numbers in a main device of the button telephone device; a control section including a microprocessor;
In order to sequentially call extension telephones corresponding to a plurality of pre-registered extension numbers in response to repeated depressions of the extension button of the extension telephone, the control sequentially controls the extension numbers read from the storage unit in response to depressions of the extension buttons. A call number sending means is provided to prompt the controller to make a call, and an extension status display command means is provided for instructing the control unit to display the status of the extension to be called, so that it is possible to make a call to the other party's extension while checking the status display of the extension. At the same time, the system has an added function that allows quick shift calls by easily selecting an extension that is not busy.

0010

[Operation] By having the present invention configured as described above, by simply pressing a single button, you can check whether the extension to be called next is busy or not, and if it is not busy, you can naturally call the original party directly. On the other hand, if the caller is busy or absent (no answer), you can quickly search for and select another extension that is not busy by repeatedly pressing the same extension button, prompting a substitute to answer the call, and waiting time for the caller. can be minimized.

First, in the operation of making a call from key telephone A102 to other telephones such as key telephone B103, when key telephone A102 is in an inactive state, the LED display of its extension button A202 shows the number of calls registered in extension button A202. Displays the status of the first extension telephone in registration order (lit in red when busy, off when not busy). For example, if the telephone registered with the highest priority in extension button A202 is key telephone B120, if key telephone B120 is busy in a talking state, speakerphone B122 or handset circuit B123 of key telephone B120 is activated. The controlling telephone control section B125 notifies the extension circuit section 105 of the key telephone main device 101 of "call circuit active" information through data transmission and reception section B126 and communication interface B127 by data transmission. This notification is sent at a fixed period (64ms)
) is performed by repeated data transmission. The extension circuit section 105 notifies the main device control section 108 of the extension port number assigned to the key telephone B120 and "call circuit active" information via the data transmission/reception section 110. The main device control section 108 inquires of the extension number management section 109 whether or not the status display control of the key telephone B120 is being performed. That is, among the multiple extension numbers registered in the extension button registration area of the storage unit 111 allocated to each extension button telephone, the button telephone B120 corresponds to the extension number currently being displayed. If a corresponding extension button is found, the extension button code and the extension port number corresponding to the key telephone to which the extension button belongs are all paired together and sent back to the main device control section 108. Here, the main device control unit 108 is notified of the extension port number corresponding to the key telephone A102 and the extension button code of the extension button A202. The main device control section 108 outputs the red lighting instruction code and extension button code corresponding to the "call circuit active" via the data transmission/reception section 110 to the corresponding extension port of the key telephone A102. button telephone A
The telephone control unit 115 of the button telephone A102 receives the red lighting instruction code and the extension button code corresponding to the extension button A202 through the communication interface A117 of the 102 and the data transmitting/receiving unit A116, decodes the code, and displays the display operation unit A11.
The lighting control of the red LED of the extension button A202 of No. 4 is performed.

If the key telephone B120 is not busy, the non-busy information issued from the telephone control section B125 of the extension telephone B120 is converted into a light-off instruction code of the main unit control section 108 by the same control, and the extension button A202 is turned off. The extension button code is sent to the telephone control unit A115 of the button telephone A102, and the extension button A202 of the display operation unit A114 is turned off.

These display controls are repeatedly performed in synchronization with the data transmission cycle. When the telephone extension at the top of the registration order is busy and cannot make a call, pressing extension button A202 causes the LED display to display the status of the next registered extension.

To explain the operation in detail, first, the telephone A1
