Abstract

PURPOSE:To prevent a response to the setting of other person by allowing communication when an operator identification number at the time of the setting of camp-on and a dial number at the time of call back coincide with each other or when a special number and the identification number are re-transmitted before prescribed time. CONSTITUTION:In a case that an extension telephone set 3 is camped-on from the extension telephone set 2, the operator dials the special number and the operator identification number, and makes a storage device 7 store them. Then, when the operator dials the identification number for the call back, and the dialed number coincides with the stored number, a response comes possible. Even though in the case that the response is not possible, the number of the telephone set 3 and the time that prescribed time is added to the time of a system clock 8 are stored in the device 7. Accordingly, if the operator dials the special number and the identification number before the stored time, and these numbers coincide with the stored numbers, a call is re-transmitted to the telephone set 3, and the communication comes possible. Thus, the response to the call back of the camp-on set by other person can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a camp-on system in an automatic private branch exchange.

(Prior art) The camp-on method in conventional automatic private branch exchanges involves making a call from an extension phone to another extension phone, and when the other party is busy dialing a special number to go on-hook, the extension phone that was in the middle of the call can be called. When the service is restored, the extension telephone that dialed the special number will ring, and the operator can go off-hook to make the call again.

(The problem that Zenkai tries to solve) Therefore, in the conventional camp-on method, when multiple people share an extension phone, they have to receive a call back from the group-on set by another person, which causes inconvenience. Something happened.

An object of the present invention is to provide a camp-on system for an automatic private branch exchange that does not cause the above-mentioned inconveniences.

(Means for Solving the Issues) To achieve the above object, the automatic private branch exchange camp-on system according to the present invention is an automatic private branch exchange having an extension automatic camp-on function.

A storage device that can store the camp-on setting extension phone number, operator's identification number, camp-on setting extension phone number and time, a system clock that outputs the time, and a special number and operator's identification number for automatic camp-on setting. When the identification number is dialed, storing the camp-on set extension telephone number and the handler's identification number in the storage device, and when the camp-on set extension telephone is no longer busy;
The camp-on set extension telephone number is read from the storage device and the camp-on set extension telephone is called back, and the identification number of the operator dialed by the camp-on set extension telephone during the call-back is stored in the storage device. If it matches the identification number of the camp-on user, a call is made to the extension telephone set for camp-on, and if they do not match, the above-mentioned storage device sends a call to the extension telephone number set for camp-on and the time output from the system clock. A specific time including one foot time is stored, and then the current time and the specific time are compared.

When the camp-on setting extension telephone dials the second special number and the handler's identification number before the specified time elapses, and the handler's identification number matches the handler's identification number in the storage device, The apparatus further comprises a control means for making a call to the camp-on setting extension and deleting all stored contents related to the camp-on setting in the storage device when the specific time has elapsed.

(Example) Hereinafter, the present invention will be explained in more detail with reference to the oral side.

FIG. 1 is a system configuration diagram showing an embodiment of a camp-on system of an automatic private branch exchange according to the present invention.

An extension telephone 2 is accommodated in the main switch 1 via a subscriber circuit 4. Similarly, an extension telephone 3 is also accommodated in the main switch 1 via a subscriber circuit 5.

The control device 6 is in charge of controlling the exchange and plays the role of a control means, and is connected to the subscriber circuits 4, 5, . It is connected to the system clock 8, storage device 7 and king switch l.

The storage device 7 has an area for storing necessary information for camp-on settings, and the area includes the calling telephone number, which is the camp-on setting extension, and the identification number of the handler.
Furthermore, if necessary, the telephone number of the called extension, which is the extension to which the middle jump-on is set, and the time are stored.

Make a call from your internal IT phone to extension phone 3, and make a call to extension phone 3.
Explain what happens when you encounter this while talking.

The operator of the extension telephone 2 dials all the special numbers and then dials the operator's identification number.

When the control device 6 recognizes that the special number sent via a register (not shown) is a camp-on setting, it accesses the storage device &7, and stores the operator's identification number and the extension phone 2 in the storage area corresponding to the extension phone 3. Accumulate numbers.

After that, when the extension telephone 3 goes on-hook and is no longer busy, the control device 6 accesses the storage device 7, reads out the number of the extension telephone 2 from the area corresponding to the extension telephone 3, and calls the extension telephone 2 a certain number of times. Make a call back.

In response to this callback, the caller at extension telephone 2 goes off-hook and dials his own identification number.

The control device fPt6 receives the identification number of the person handling the extension telephone 2 sent via the register.

The storage device 7I is accessed, the identification number is read from the area corresponding to the extension telephone 3, and these identification numbers are compared.

As a result of the comparison, if they match, the calling party (IIl) is sent to the extension telephone 3.

As a result, if the operator of extension telephone 3 goes off-hook, extension telephones 2 and 3 will be connected and a call will be possible.On the other hand, if the result of the call does not match, the number of extension telephone 3 and the system clock 8 will be displayed. The time is stored in an area other than the above-mentioned area of the time total storage device 7, which is a predetermined time added to the time, and call-back is stopped. Then, the number of extension telephone 2 in the storage area corresponding to extension telephone 3 is deleted. As a result, only the identification number of the operator of the extension telephone 2 remains in the area corresponding to the extension telephone 3 of the storage device 7, and the number and time of the extension telephone 3 are stored in other areas.

After that, l! The iljwJ device 6 matches the time stored in the storage device 7 at regular intervals with the time of the system clock 8, and if they match, stores the extension telephone 30 number and time stored in the storage device 7, and the extension number. The operator of the telephone 2 dials and deletes the operator identification number from the storage device 7.

If the operator of the extension telephone 2 dials the special number and operator identification number before the time stored in the storage device 7 and the time indicated by the system clock 8 match, the control device 6 dials the operator identification number. The number is compared with the operator identification number stored in the storage device 7, and if they match, the number of the extension telephone 3 stored in the storage device 7 is read out.
control outgoing calls. When the extension telephone 3 goes off-hook, the call becomes 0T functional.

(Effects of the Invention) As explained above, according to the present invention, the identification number of the person to be treated as a friend that is dialed when setting up camp-on matches the number that is dialed when the call-back is ringing. You can only answer the call back if you are unable to do so.

The extension phone number of the camp-on user is stored for a certain period of time, and the user can respond to a camp-on callback set by another person by dialing the special number and the operator identification number at the time of setting camp-on. It is possible to prevent this from happening. Therefore, even if you are away from your seat when the call-back rang and you want to discuss, there is no need to look up the number and call again.
