Abstract

PURPOSE:To immediately and easily discriminate incoming call to a subscriber by calling a dedicated terminal designated by a private branch exchange, and informing the incoming call to a common terminal in voice or visually. CONSTITUTION:The common terminal 2, in the case of receiving information from an opposite terminal 4 and reading the number (address number) of the dedicated terminal 3 with an address to perform incoming call guidance designat ed by an outgoing person in reception information, informs the address number and its own common terminal number to a central control unit 10 via a commu nication path 14. The central control unit 10 retrieves an incoming call guidance registration table setting informed common terminal number and address number as a key, and obtains the attribute information of a corresponding dedicated terminal 3 by indexing another table when the dedicated terminal that coincides with the address number exists. When the attribute of the dedicated terminal 3 is a voice terminal, the central control unit 10 connects the dedicated terminal 3 to an audio response unit 11 via a communication path network 13, and calls the dedicated terminal 3. In such a manner, it is possible to immediately and easily discriminate at which subscriber the incoming call arrives when the incoming call arrives at the common terminal 2.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an incoming call guidance system, and in particular, incoming calls to a private branch exchange that accommodates a common terminal used jointly by multiple subscribers, such as a facsimile or teletext device. Regarding guidance methods.

[Conventional technology]

Conventionally, when an incoming call is received to a joint terminal used jointly by multiple subscribers, the private branch exchange only connects to this joint terminal and determines which subscriber among the multiple subscribers the call is addressed to. There was no guidance to identify and notify incoming calls.

[Problem to be solved by the invention]

In the conventional method described above, multiple subscribers using a shared terminal must constantly check whether there are incoming calls addressed to them, and even if calls are received, the calls do not arrive until they are checked, which reduces work efficiency. It had the disadvantage of hindering the

SUMMARY OF THE INVENTION An object of the present invention is to provide an incoming call guidance system that can immediately and easily determine which subscriber the incoming call is addressed to when a call arrives at a communal terminal, and does not impede business efficiency.

[Means for Solving the Problems] The incoming call guidance system of the present invention is directed to the above-mentioned private branch exchange that accommodates a common terminal jointly used by a plurality of subscribers and a dedicated terminal used exclusively by each subscriber. In the call notification method when a call is received at a joint terminal, the joint terminal is connected to a partner terminal and has means for communicating with the private branch exchange during communication, and the joint terminal performs call guidance from information received from the partner terminal. identifying the designated information of the dedicated terminal to be notified of and notifying the private branch exchange, and the private branch exchange calls the designated dedicated terminal and notifies by voice or visual display that there is an incoming call to the communal terminal; It is characterized by notifying.

[Example〕 Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of a private branch exchange for explaining one embodiment of the present invention.

The private branch exchange 1 is an electronic private branch exchange using a storage program control system, and includes a central control unit 1 including a storage device (not shown).
0, a voice response device 11 and an information receiving device 12 that can be directly controlled from this central control device mtlO, and a communication path network 13.
It is equipped with The communal terminal 2 is a facsimile terminal, a teletext terminal, or the like, and can communicate with the private branch exchange 1 via the communication path 14 while communicating with a partner terminal. The dedicated terminal 3 is a telephone terminal or a keyboard terminal with a visible display and is used exclusively by the subscriber. The partner terminal 4 is a facsimile terminal, teletext terminal, etc. accommodated in a public network outside the tank, and can make and receive calls to and from the communal terminal 2.

FIG. 2 is a configuration diagram showing an example of an incoming call guidance registration table in the storage device of the central control unit 10, in which calls are received to the communal terminal 2 in correspondence with the number of the communal terminal 2 (hereinafter referred to as the communal terminal number). Dedicated terminal 3 that should notify incoming call guidance if
number (hereinafter referred to as the dedicated terminal number) is registered.

First, a method of registering numbers in the call guide registration table will be explained. This registration is performed from the dedicated terminal 3. When the subscriber calls a pre-specified registration number from the dedicated terminal 3, the private branch exchange 1 connects the dedicated terminal 3 to the information receiving device 12 via the communication path network 13. When the subscriber transmits the joint terminal number and the dedicated terminal number, the information is transmitted from the information receiving device 12 to the central control unit 10, and is registered in the incoming call guide registration table in the storage device in a pointer format corresponding to the joint terminal number.

Note that this registration can be done not from the dedicated terminal 3, but when setting the station data.

Next, a case where a call arrives from the partner terminal 4 to the joint terminal 2 will be explained. The private branch exchange 1 transfers the line on which the call was received to the communication network 13.
Connect to communal terminal 2 via . The joint terminal 2 receives information from the other party's terminal 4 according to a procedure determined between the terminals, and includes the number of the dedicated terminal 3 of the destination specified by the caller in the received information (hereinafter called the destination number). ) is read, the central control unit 10 is notified of this destination number and its own joint terminal number via the communication path 14. The central control device 10 searches the call guide registration table using the notified joint terminal number and destination number as keys, and if there is a dedicated terminal number that matches the destination number,
Corresponding dedicated terminal 3 by indexing a separate table (not shown)
Get the attribute information of.

If the attribute of the dedicated terminal 3 is a voice terminal, the central control unit lO
is connected to the dedicated terminal 3 and the voice response device 1 via the communication path network 13.
1 and calls the dedicated terminal 3. When the subscriber answers, the central control device 10 controls the voice response device 11 and notifies the communal terminal 2 by voice that the call has arrived.

If the attribute of the dedicated terminal 3 is a keyboard terminal with a visible display, the central control unit 10 calls the dedicated terminal 3 via the communication path network 13, and if the subscriber answers, it will notify that the communal terminal 2 has received a call. Display as visible information.

As described above, when a call arrives at the communal terminal 2, it is possible to immediately and easily determine which subscriber the call is addressed to.

Further, if the destination number and the registered dedicated terminal number do not match, the central control unit 10 does not perform the operation of notifying the incoming call guide.

Although this embodiment has shown an example in which the dedicated terminal 3 that should provide incoming call guidance is registered, it is also possible to unconditionally provide incoming call guidance to the dedicated terminal 3 with a specified destination number without requiring registration. It is.

Alternatively, the communication path 14 may not be used as a method for notifying the destination number and the communal terminal number from the communal terminal 2 to the private branch exchange 1, but the following method may be used. That is, when the joint terminal 2 is connected to the partner terminal 4 and receives the destination number,
It automatically performs hooking and requests the private branch exchange 1 to restore the connection, and when connected to the private branch exchange 1, notifies the destination number. When the private branch exchange 1 is notified of the destination number from the shared terminal 2, it determines the shared terminal number from the connected line, starts searching the call guide registration table, and connects the shared terminal 2 to the partner terminal 4. fix.

Further, although the partner terminal 4 is accommodated in an exchange that forms a public network, it is also possible to implement the present invention even when the partner terminal 4 is accommodated in the same private branch exchange as the shared terminal 2.

〔Effect of the invention〕

As explained above, according to the present invention, subscribers using a shared terminal such as a facsimile or teletext device can instantly receive a call addressed to them at the shared terminal using a dedicated terminal nearby. Moreover, since it is easy to know, there is no need to go to the location of the shared terminal regularly to check, and the information can be obtained as soon as a call is received, which has the effect of not interfering with work efficiency.
