Abstract

PURPOSE:To attain transfer to a proper transfer destination by storing plural transfer destination extension numbers corresponding to plural designation time to a built-in storage means of an extension telephone set and connecting a call automatically to an extension telephone set of a visit place. CONSTITUTION:When a current time belongs to a time zone at which transfer to, e.g. a 2nd extension telephone set 3 is decided, an extension number of the 2nd extension telephone set 3 stored in a storage device is read and a relevant department and section name corresponding to the extension number is searched from a database 11 and the name is sent to a voice transmitter 12. The voice transmitter 12 converts the received relevant department and section name into a voice signal and sends to a handset of a 4th extension telephone set 5, to which the transfer destination is informed. When the operator of a 4th extension telephone set 5 makes no operation for a prescribed time, a central controller 10 controls the system to call the 2nd extension telephone set 3 being a visit place, and extension mutual talking is made through the reply of the operator of the 2nd extension telephone set 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a private branch exchange that automatically connects arbitrary extension telephones to each other, and particularly relates to a call forwarding system between a plurality of extension telephones.

[Conventional technology]

In the conventional call forwarding system, when you leave your seat with your own extension phone, you set the extension number of the forwarding destination by dialing from your own extension phone, and then the call is forwarded to your extension phone. automatically connected to the destination phone extension.

[Problem to be solved by the invention]

In this way, conventional call forwarding settings are performed by dialing the forwarding destination's extension number from your own extension telephone when you leave your desk at the packing machine. Due to the schedule, if you do not have time to return to your desk and go to the next destination, you will not only be transferred to the previous destination, but the caller will also be transferred to the next destination. has the problem that it is not possible to know that forwarding has been set up before the forwarding occurs.

[Means to solve the problem]

The call forwarding method of the present invention is implemented in a private branch exchange that accommodates multiple telephone extensions and automatically connects any predetermined extension telephones, with the name of the department associated with each extension number registered in advance. database, and a voice transmission device that converts the name of the department to which a call belongs to into voice and transmits it to the caller, and the extension telephone has a built-in storage means, and the special number for call forwarding setting is transmitted from the extension telephone of the forwarding source. After pressing , by repeatedly registering the transfer destination extension number along with the transfer start time and transfer end time, the transfer destination extension numbers corresponding to a plurality of specified times are stored in the storage means, and the call is received at the transfer source extension telephone. If there is, read out the corresponding forwarding destination extension number,
The name of the department that corresponds to the forwarding destination extension number is searched from the database, converted to voice by the voice transmitting device, and sent to the caller to notify the forwarding destination by voice.After this, the caller does nothing for a certain period of time. When the extension telephone is not operated, the telephone is connected to the extension telephone of the transfer destination, and the transfer destination information whose transfer time period has already elapsed is deleted from among the transfer destination information stored in the storage means.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

Referring to FIG. 1 showing one embodiment of the present invention, 1 is a main switch constituting a private branch exchange, and 2, 3, 4, and 5 are extension telephones each having a built-in storage device (not shown). Among these &! The telephone set is connected to the main switch 1 via correspondingly provided subscriber circuits 6, 7, 8.9. Further, 10 is a central control unit that controls each part of the private branch exchange, 11 is a database in which the name of the department associated with each extension number has been registered, and 12 is the name of the department read out from the database 11. This is an audio transmitting device that converts and transmits the audio.

In such a configuration, the operator of the first extension telephone 2 first off-hooks the extension telephone 2 at his/her desk, presses the special number for call forwarding settings, and then selects the transfer start time and transfer end time to the second extension telephone 3. Following the time, dialing the extension number of the second extension telephone 3 to which the transfer is to be made will call the central control unit 10.
sends the extension number of the second extension telephone 3 to which the user is away and the above-mentioned time to the storage device built in the first extension telephone 2 which is the transfer source. The corresponding storage device stores the sent information. Similarly, if the operator of the first extension telephone 2 wants to set the forwarding destination to the third extension telephone 4 in addition to the second extension telephone 3, proceed to the previous operation and change the forwarding destination to the third extension telephone 4. When dialing the transfer start time, transfer end time, and extension number of the third extension telephone 4 of the transfer destination, the central control device 1
0 sends the extension number and the above-mentioned time of the third extension telephone 4 to which you are leaving to the storage device built in the first extension telephone 2 which is the transfer source, and the corresponding storage device receives the sent information. Accumulate.

From this state, the central control unit 1o monitors and compares the system clock time and the time stored in the built-in storage device of the first extension telephone 2, and when the transfer end times match, the central control unit 1o outputs the corresponding information. Automatically erase and cancel transfer function0
When the times do not match, that is, when the transfer function is not canceled, for example, when the operator of the fourth extension telephone 5 dials the extension number of the first extension telephone 2, the central control unit 1o The transfer start time and the transfer end time to the destination stored in the storage device are used to determine whether it is the transfer time zone, and if it is outside the transfer time zone, the first extension telephone 2 is directly called. If this is not the case, that is, if the current time is a time period in which transfer should be made to the second extension telephone 3, the extension number of the second extension telephone 3 stored in the corresponding storage device is read out and the extension number is retrieved from the database 11. The department/section name corresponding to the extension number is found and sent to the voice sending device 12. The voice transmitting device 12 converts the received department/section name into voice, transmits it to the handset of the fourth extension telephone 5, and notifies the transfer destination. Thereafter, when the operator of the fourth extension telephone 5 does not perform any operation for a certain period of time, the central control unit 10 controls the second extension telephone 3 at the place where the user is away from the seat to be called, and the second extension telephone 3 When the person handling the call responds, the call becomes a mutual extension call.

〔Effect of the invention〕

As explained above, according to the present invention, after pressing the special number for call forwarding settings from the transfer source's extension phone, the transfer destination extension number is repeatedly registered along with the transfer start time and transfer end time. The storage means can store forwarding destination extension numbers corresponding to multiple designated times, and from now on, when a call is received on the transfer source extension phone, the corresponding forwarding destination extension number is read out and automatically connected to the away optical extension phone. Even if the destination changes one after another, if call forwarding is set, the call can be forwarded to the appropriate destination. Furthermore, since the caller is notified of the forwarding destination by voice and is only transferred if no operations are performed for a certain period of time, the caller can choose whether or not to forward the call.
