JPH03212053A - Private branch exchange with no reply transfer - Google Patents

Abstract

PURPOSE:To eliminate the need for a trouble for the called party having to listen to a ring tone for a while when the called party is busy and desires to transfer a call to other party regardless of his presence and for a caller having to wait for the transfer time by devising the system such that the call received already is able to be transferred even in a calling mode to a registered extension by the operation from a telephone set receiving the call. CONSTITUTION:When a call comes to an extension telephone set 5 and the immediate reply to the arrived call is impossible, a controller 2 recognizes it that a no-reply transfer request comes from the extension telephone set 5 via an extension circuit 4 by operating the no-reply transfer switch of the extension telephone set 5. The controller 2 retrieves a memory of a storage device 3 and extracts a n-reply transfer destination extension number of the extension telephone set 5 and transfers the call reaching the extension telephone set 5 to the transfer destination extension. Thus, the call is handled tentatively by other extension telephone set without listening to a ring call for a while because the called party is busy occupied for another job and cannot reply the arrived call to the extension telephone set and without keeping the caller waiting for a long time.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a private branch exchange with a no-response transfer function.

2. Description of the Related Art In recent years, switching equipment (including key telephone equipment) has become highly electronic, and various convenient functions have been added in addition to switching functions.

Call forwarding is one such feature, but conventionally, this type of call forwarding function has been used to call a private branch exchange by dialing the call forwarding special number and the forwarding destination's extension number from a telephone extension. The extension number was stored in the main memory of the private branch exchange, and when a call was received to this extension telephone and there was no response for a certain period of time, a pre-registered transfer call was made to the extension number.

Problems to be Solved by the Invention However, with the above-mentioned conventional private branch exchange, the transfer is not performed until a certain non-response time has elapsed, so even if the recipient is present, he or she is busy and wants to transfer the message to someone else. There was a problem in that the caller had to keep listening to the ringing sound during that time, and the caller had to keep waiting during that time.

The present invention solves these conventional problems,
To provide an excellent no-response transfer device for a private branch exchange capable of transferring even an incoming call to an already registered extension by a simple operation from an incoming telephone.

Means for Solving the Problems In order to achieve the above object, the present invention stores the extension number of the non-response forwarding destination in advance in the storage device of the exchange, and registers the no-response forwarding destination set in the telephone which is the extension of the exchange. When a function switch (non-response transfer switch) for instructing a request is operated while an incoming call is ringing, the incoming call is transferred to a non-response transfer destination stored in advance in the storage device of the exchange.

Therefore, according to the above configuration, even if an incoming call is being received by an extension telephone, by operating the no-response transfer switch, the incoming call will be transferred to a pre-registered extension telephone.

Example An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, a private branch exchange A includes a communication path device 1 that connects lines to each other, a control device 2 that controls the entire exchange,
It has a storage device 3 for storing control information of the control device 2 and an extension circuit 4, which are connected as shown in the figure. The central office line or external line 8B is connected to the communication line equipment l of the private branch exchange A. A multifunctional extension telephone 5 having at least a non-response transfer switch and a switch capable of setting various functions of the exchange is connected to the communication path device 1 via the extension circuit 4.

To explain the operation of the embodiment of the present invention configured as described above, the extension number of the forwarding destination is registered in the own memory area of the storage device 3 to the private branch exchange using the special number from the extension telephone 5. put.

When there is an incoming call on the extension telephone 5 and the incoming call cannot be answered immediately, operating (for example, pressing) the non-response transfer switch on the extension telephone 5 transfers the call to the extension circuit 4.
The control device 2 recognizes that the non-response transfer request was received from the extension telephone 5 via the controller 2, searches the memory of the storage device 3, retrieves the extension number of the non-response transfer destination of the extension telephone 5, and sends it to the extension telephone 5. Transfer incoming calls to the destination extension. Note that this exchange also includes a small-scale key telephone device.

Note that in the above embodiments, the extension telephone is not limited to a multi-function telephone; it is sufficient if it has at least a no-answer transfer switch (button), or a certain dial button (such as a book).
This function may also be performed by pressing .

Note that the setting of the forwarding destination may be operated on the button telephone device side, regardless of the special number.

Effects of the Invention As is clear from the above-mentioned embodiments, the present invention is such that even when an extension telephone is receiving a call, the receiving party can temporarily change the receiving party by operating the receiving telephone. This has a great practical effect in that when you are busy and cannot answer an incoming call to your extension phone, you can temporarily have another extension phone handle it without having to keep hearing the ringing sound or making the other party wait for a long time.
