Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a button telephone device and a call transfer method in a private branch exchange.

(Prior art) Conventionally, in this type of call transfer method, the transfer operation was repeatedly executed when the transfer destination was busy or did not answer. Figure 4 shows an extension that answered one incoming call from an outside line. FIG. 3 is an operation flow diagram showing the operation flow when transferring a call to another extension using the telephone. When a call is received from an outside line, a specific telephone (including the operator at the attendant stand) or the telephone that noticed the call is used to answer (S, , ), and when a request is made to connect to extension Oo from the outside line.

For example, after hooking, the telephone that answers performs a transfer operation consisting of a special number for identifying the forwarding function (hereinafter referred to as the special number) and the forwarding destination telephone number (S4-) - If the forwarding destination extension is free and the call is answered, By going off-hook, the transfer source telephone connects the outside line and the extension oQ and can make a call (S43). If the transfer destination extension is busy or does not respond even after ringing, the transfer source telephone performs the transfer operation again. In this case, the transfer destination extension number is XX near Oo. In this way, it was possible to transfer calls using the conventional method.

(Problem to be solved by the invention) However, in the conventional call transfer method described above.

There is a problem in that when the transfer destination is busy or does not respond, the transfer source needs to repeat the transfer operation until the transfer destination responds. Some switching equipment (key telephone equipment or private branch exchanges) has a busy call forwarding/absent call function, but only one forwarding destination can be automatically redirected, and if the forwarding destination is busy or does not respond, There was a problem that the call would become invalid when

The present invention solves these conventional problems,
The purpose of this invention is to provide an excellent transfer method that can achieve the transfer purpose with a single transfer operation.

(Means for Solving the Problems) In order to achieve the above object, the present invention divides an extension into a plurality of groups, and includes means for storing the group division, means for detecting whether the transfer destination is busy, and a transfer destination. a timer means for counting the time since the forwarding destination receives the call; and a timer means for counting the time since the forwarding destination receives the call; It is equipped with an extension connection information generation means for connection and a communication path control means.

(Function) Therefore, according to the present invention, if the transfer source executes the transfer operation, when the transfer destination is busy or does not respond, the incoming call can be displayed on other extensions in the transfer destination group, and the call can be transferred. This has the effect of eliminating the need to repeat the operation multiple times.

(Example) FIG. 1 shows an outline of connections in an embodiment of the present invention.

In Figure 1, 1 is a switching device, 2 is an outside line (plurality), l
O is an extension telephone belonging to group 1, and 15 to 18 are extension telephones belonging to group 2.

FIG. 2 is a diagram showing functional blocks of an embodiment of the present invention, and is a part of the functional blocks of the switching device 1 shown in FIG.

In FIG. 2, 21 is a communication path control circuit that connects and controls communication paths in the switching equipment, 22 is a group definition storage circuit that defines and stores groups, and 23 is a busy detection circuit 2.
4 and a response detection circuit 25, and an extension automatic connection information generation circuit that generates extension information to be automatically connected next based on information in the group definition/memory circuit; 25 is a response detection circuit for detecting the response state of the transfer destination telephone, and 26 is a timer.

FIG. 3 is an operation flow diagram showing the operation flow of one embodiment of the present invention.

Next, the operation of the above embodiment will be explained with reference to FIGS. 1 to 3. In FIG. 1, an incoming call is received at the switching device 1 from one of the plurality of outside lines 2, and the extension telephone 10 receives a call from one of the outside lines 2.
Suppose that the user responds (S, 1.S, . . . in Figure 3). If there is a connection request from the outside line 2 to the extension telephone 15 (Fig. 3, 5-3), the extension telephone 10 will call the special number (for example, 8 is the special number for call transfer) and the extension telephone number 15, 815.
(834 in Figure 3). Above extension telephone IO
dial 815, the communication path control circuit 21 of FIG.
The busy detection circuit 124 checks whether the extension telephone 15 is busy (FIG. 3, So). If the extension telephone 15 is not busy, the call path control circuit 21 connects the extension telephone 15 to a ring tone sending circuit (not shown), and also connects the response detection circuit 25 to the extension telephone 15 to monitor the response. do.

Also, the timer 26 monitors whether a response is made within a certain period of time. If the extension telephone 15 answers within a certain period of time,
A call path control circuit 21 connects the outside line 2 and the extension telephone 15, and a call can be made (S., S,, . . . in FIG. 3). Further, if the extension telephone 15 does not respond within a certain period of time, the timer 26 and response detection circuit 25 shown in FIG. 2 inform the extension automatic connection information generation circuit 23 that the time has elapsed.

The automatic extension connection information generation circuit 23 learns the numbers of the remaining extension telephones 16, 17, and 18 in group 1 to which the extension telephone 15 belongs from the group definition/storage circuit 22, and notifies the communication path control circuit 21 of this information. The call path control circuit 21 displays the incoming call on the extension telephones 16, 17, and 18 (Fig. 3 S).
3. ), extension telephone 16, 17, or 18 responds, the call is transferred to that telephone and the call can be made to the outside line. At this time, the incoming call display for extension telephones other than those that answered is canceled.

When the extension telephone 10 dials 815 for the first time and the transfer destination extension telephone 15 is busy, a signal is sent from the busy detection circuit 24 in FIG. The operation is the same as if the transfer destination extension telephone did not answer within a certain period of time.

Note that if the extension telephone that receives the call first responds within a certain period of time, the incoming call will not be displayed on other extension telephones in the same group.

Although the above explanation deals with transfer of an incoming call from an outside line, the same method can be used for an incoming call from an internal line. Further, in the above description, the case where the first response is made by the extension telephone is described, but in the case of a private branch exchange, the same can be done when the operator of the relay board answers first and transfers the call.

(Effects of the Invention) As is clear from the above embodiments, the present invention has the effect that the probability of performing a call transfer operation in one time is extremely high, and the operational efficiency is dramatically improved.
