Abstract

PURPOSE:To eliminate the problem of forgetting of no-response call transfer setting or erroneous setting due to erroneous dialing by storing the number of incoming calls, which fail to get the response, in each telephone set and automatically setting no- response call transfer to an extension telephone set at the time of arrival of this number at a preliminarily set number of incoming calls for no-response call transfer. CONSTITUTION:When a call comes to an extension telephone set 1, the number of no-response incoming calls in a no-response incoming call number storage device 5 and that of incoming calls for no-response call transfer in a storage device 7 of the number of incoming calls for no-response call transfer setting are compared with each other, and when the former is smaller, incoming is continued without setting no-response call transfer, and the number of no-response incoming calls is incremented if this incoming call fails to get the response. When the number of no-response incoming calls in the storage device 5 exceeds that of incoming calls for no-response call transfer in the storage device 7, a central controller 4 automatically sets no-response call transfer, and the incoming call is transferred to a transfer destination stored in a no-response call transfer destination storage device 6 when the incoming state continues without response for a certain time.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a non-response transfer device using a private branch exchange or the like.

BACKGROUND OF THE INVENTION In recent years, telephones and exchanges have become highly electronic, providing a variety of convenient functions. One of them is the no-response transfer function.

Conventional no-answer forwarding devices of this type set a no-answer forwarding destination for each extension phone through program settings in advance, and when a special number is dialed from the extension telephone, the dial is analyzed within the exchange and no-answer forwarding is performed. The no-response transfer setting can be canceled each time by setting the no-response transfer, or by dialing the special number and then dialing the extension number of the non-response transfer destination in the exchange, and then dialing the special number.

Problems to be Solved by the Invention However, in the above-mentioned conventional no-response forwarding device, the no-answer forwarding setting requires the telephone operator to enter a special number dial or the subsequent forwarding destination extension number each time. There were problems such as forgetting to make settings, incorrect settings due to incorrect dialing, and misunderstandings.

The present invention solves these conventional problems,
There is no need to configure unanswered forwarding settings each time, and once you have set the unanswered forwarding destination using a program setting or special number, calls will continue to be unanswered even if the telephone operator does not have to dial the special number each time. It is an object of the present invention to provide an excellent non-response transfer device that can automatically set a non-response transfer.

Means for Solving the Problems In order to achieve the above object, the present invention provides a storage device for the number of unanswered incoming calls that records the number of incoming calls that end in no answer for each extension telephone, and a storage device for recording the number of incoming calls that end in unanswered calls when no-answer forwarding is set. A non-response transfer destination storage device for setting a valid non-response transfer destination, and a non-response transfer 3 set number of incoming calls storage device for setting the number of unanswered incoming calls for automatically setting the no-answer transfer, When the number of unanswered incoming calls on a certain extension telephone reaches the preset unanswered forwarding set number of incoming calls, unanswered forwarding is automatically set.

Therefore, according to the present invention, when an unanswered incoming call occurs, the number of occurrences is stored for each telephone, and when the number of unanswered incoming calls reaches a preset number of unanswered forwarded incoming calls, the extension is automatically transferred. You can set a no-answer forwarding setting for your phone.

Embodiment A non-response transfer device for a private branch exchange according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. As shown in the figure, a main switch 3 constituting a private automatic branch exchange is connected to a central control device 4 and is connected to a main switch 3 via a subscriber circuit 2. It is connected to extension telephone 1. Note that the subscriber circuit 2 is connected to and controlled by a central control device 4. The central control device 4 also includes a storage device 5 for the number of unanswered calls, a storage device 6 for the destination of unanswered calls, and a storage device 7 for the number of unanswered transfer settings.

FIG. 2a shows the memory contents in the unanswered incoming call number storage device, and FIG. 2b shows the memory contents in the unanswered forwarding destination storage device. FIG. 3 is a processing flow diagram of a process in which non-response transfer is automatically set.

Next, the operation of an embodiment of the present invention configured as described above will be described.

In FIG. 3, when an incoming call occurs on the extension telephone 1, the number of unanswered calls stored in the memory in the number of unanswered calls recording device 5 and the number of unanswered calls stored in the storage device 7 for the number of unanswered calls set in FIG. If the number of unanswered forwarded incoming calls is compared and the unanswered incoming call count is smaller, the unanswered forwarding is not set and the incoming call continues, and when this incoming call ends in no answer, the unanswered incoming call count is incremented. do. In addition, several incoming calls that ended in no response continue, and another incoming call occurs, and the unanswered incoming call number storage unit 5
When the number of unanswered incoming calls in the memory exceeds the preset number of unanswered forwarded calls in the unanswered forwarding setting incoming call storage device 7, the central R control device 4 automatically sends unanswered calls. After setting the transfer, if the incoming call continues unanswered for a certain period of time, the incoming call is transferred to the transfer destination in the memory in the non-response transfer destination storage device 6 shown in FIG. Further, the unanswered transfer setting is canceled by taking the telephone off-hook and clearing the memory in the unanswered call count storage device 5 corresponding to the telephone.

According to the embodiment described above, when an unanswered incoming call occurs, the number of times it has occurred is memorized for each telephone, and when the number of unanswered calls reaches the preset number of unanswered forwarded calls, the extension is automatically transferred. You can set a no-answer forwarding setting for your phone.

Note that this device may be provided in a key telephone device having an exchange function.

Effects of the Invention As is clear from the above embodiments, the present invention can provide the following excellent telephone system that is easy to use.

(1) Even if the telephone operator does not input a special number dial,
If the phone continues to receive unanswered calls, the unanswered call forwarding setting is automatically set to 6, so there is no need to configure the settings each time as in the past. This eliminates the problem of incorrect settings.

(2) Since no-response forwarding can be canceled automatically by going off-hook of the telephone without dialing from the telephone, problems such as forgetting to cancel or mistakenly canceling the transfer do not occur.
