Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private branch exchange capable of providing group search and call transfer services. Recently, with the computerization of telephone exchange systems, various subscriber services have become available. The incoming call transfer service is one of them, and is a service in which when the incoming call cannot be answered, the transfer destination is designated in advance and the incoming call is transferred to the transfer destination.

Particularly, in an office or the like having a private branch exchange (PBX), when the calling party is busy, if the calling party belongs to a predetermined search group (Hunting Group), The private branch exchange can automatically search for a free terminal inside and connect to it.

When there is no member in the search group who can respond due to absent or busy reasons, and when all the members want to transfer to a common number, conventionally, the transfer destination registration number is registered in advance in the telephone that first receives the call. If so, the incoming call is transferred to this transfer destination, and in order for the members of the search group to transfer to the common place, all the members have to re-register the common transfer destination.

Further, even if the forwarding number is not registered to the first called party, if this called party is busy, a vacant number is searched in sequence among the members forming the search group. , If there is no vacancy, the first called party will be put on hold (Camp on). Further, when searching sequentially, if the transfer destination number is registered in any of the members' terminals, there is the inconvenience of being transferred to this registration destination.

In addition, in the service for forwarding the incoming call, the forwarding number is registered from each telephone (Call Forwarding).
There are two types: a method and a method in which the system administrator registers the forwarding number using a console or the like (System Forwarding).

[0006]

2. Description of the Related Art FIG. 5 shows an example of a connection configuration of each terminal in a conventional work place forming a search group. In the figure,
The telephone number of manager A is 1110, and the telephone number of secretary A is 1111
No., Section A's phone number is 1112, Section B's phone number is 11
The phone number of No. 13 and section X is 111x, the phone number of the transfer office B of manager A is 2222, and the transfer secretary of secretary A is B
, The telephone number of the conference room you want to transfer
Number 3333.

Consider a case where each terminal is busy in a workplace where a search group is conventionally formed, and an incoming call is shifted by a route shown by an arrow in the figure. If everyone leaves the meeting at this time, I would like to transfer it to the meeting room.
Office B, which is normally used by manager A, is the transfer destination.
If CFD (Call Forwarding) / System Forwarding = 2222 is registered, this incoming call to the manager A will be forwarded to the office B (case A).

Therefore, in order to transfer to the conference room, the manager A must re-register the transfer destination in the conference room (3333). Also, when a call arrives at another member, for example, the manager A
Is busy and the call is shifted to Secretary A, Secretary A
If the transfer destination is normally registered in secretary B, this call will be transferred to secretary B (case B). Under such circumstances, when the members of the search group consider the call transfer to the same location, it is very inconvenient at present that all the members have to re-register the transfer destination. If the transfer destination is registered, canceled, and re-registered each time the user leaves the desk, an erroneous transfer due to an input error may occur.

[0009]

Therefore, reliable transfer to the required place such as transfer to the call transfer destination registered in the telephone that first received the call cannot be realized, or the call is transferred. Since it is necessary to check the availability of all the members of the search group, it takes time until the call is actually connected, and there is a possibility that incorrect input may be caused by changing the forwarding number frequently. Was lacking in.

An object of the present invention is to quickly and accurately transfer a call for each search group when members of the search group desire to transfer a call to a common place.

[0011]

FIG. 1 is a block diagram showing the principle of the present invention. In the figure, 1 is a processing unit, 2 is a memory unit, 3
Is a transfer registration detecting means in search group units, 4 is a first transfer registration detecting means for registering transfer destinations from each telephone when there is no member in the search group, and 5 is a search group for registering transfer destinations from a system administrator. Second transfer registration detecting means when the member does not respond because the incoming call is rejected, 6 is a case where a member of the search group performing the transfer destination registration from each telephone is busy or there is no response to the call for a certain period of time. No. 3 of the third transfer registration detecting means, 7 is the fourth transfer registration detecting means when the member of the search group for registering the transfer destination from the system administrator is absent, and 8 is for the search group for registering the transfer destination from the system administrator. If the member is busy,
Alternatively, the fifth transfer registration detecting means when there is no response to a call for a fixed time is shown.

According to the present invention, the transfer registration detecting means 3 for each search group in the processing unit 7 searches the object table 9 of the search group number, the member and the transfer destination number in the memory unit 2, and the transfer destination for each search group. If the number is registered, it is transferred to the transfer destination of the search group unit, and if the transfer destination number of the search group unit is not registered, the telephone of each registration destination by the first to fifth transfer registration detecting means as before. Configure to forward to a number.
