DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incoming call notification control system for a private branch exchange.

[0002]

2. Description of the Related Art Heretofore, this type of incoming call notification control method has been adopted when a private electronic exchange accommodates voice mail.
When an incoming call arrives at a busy extension terminal, the incoming call arrives at voice mail, and when the busy extension terminal recovers, the extension terminal is notified unconditionally that the incoming call has arrived at voice mail. If voice mail is not accommodated in the electronic exchange and forwarding is not set to the receiving terminal, the incoming call cannot be automatically received at another extension terminal.

[0003]

In this conventional incoming call notification control system, if the receiving terminal has not set the transfer, or if the receiving terminal does not respond, the caller once recovers to another extension terminal. The disadvantage is that you have to start over.

[0004] In addition, when voice mail is not accommodated and there is an incoming call at an extension facsimile terminal, there is a drawback that the caller must make another call to another extension terminal to notify that the facsimile transmission has been performed. .

[0005]

According to the present invention, there is provided an incoming call notification control method for a private branch exchange which accommodates a plurality of extension terminals, wherein the private electronic exchange has a communication control interface to an external computer. Interface means, and first notifying means for notifying the external computer of the information of the incoming call when receiving and responding to the facsimile terminal accommodated in the private branch exchange; The external computer that has received the information has storage means for calculating and storing a response time corresponding to the facsimile terminal, and the private branch exchange has been restored after the facsimile terminal has finished receiving the incoming call. In such a case, there is provided second notification means for notifying the external computer of the recovery information, and the external computer Upon receiving the recovery information, a third notification unit is provided for notifying the specific telephone terminal accommodated in the private electronic exchange registered in advance that the facsimile terminal has arrived and the response time to the private electronic exchange. The private branch exchange further notifies the specific telephone terminal of the incoming call and the response time of the facsimile terminal based on information from the third notification means.
Notification means.

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the first invention.

In FIG. 1, this embodiment comprises a private branch exchange (PBX) 1 and an external computer unit 6. The PBX 1 has a line circuit (LC) 12-1 that interfaces with a facsimile terminal (FAX). , LC12- interface to a telephone terminal (hereinafter STA)
2 and an incoming trunk (hereinafter referred to as T
RK) 13, LC12-1, 12-2 and TRK1
A switch (hereinafter referred to as SW) 11 for connecting the three, an interface section (hereinafter referred to as IP) 15 for interfacing with the external computer section 6, and a central control device (hereinafter referred to as CPU) 14 for controlling the entire PBX 1. I have.

The external computer unit 6 calculates and accumulates a response time to the incoming call of the FAX 2-1 and stores it in the FAX 2-1.
The telephone terminal for notifying the incoming call to -1 has storage means registered in advance.

FIG. 2 is a diagram showing a processing sequence when an incoming call is received at the facsimile terminal in the present embodiment.

Next, the operation of this embodiment will be described with reference to FIGS.
This will be described with reference to FIG.

When there is an incoming call from the TRK 13 to the FAX 2-1, the CPU 14 performs connection processing (a). And CPU
When the FAX 14 recognizes the response of the FAX 2-1, it sends only a response notification to the effect that "the FAX 2-1 has responded" to the external computer 6 via the IP 15 (b). Then, the external computer unit 6 that has received the notification accumulates the time information therein (c).

When the reception of the fax 2-1 is completed, the fax 2-
When the CPU 14 recognizes a recovery request from the FAX 2 through the LC 12-1, the FAX 2-1 and the TRK are
13 (e). Then, the CPU 14
Upon recognizing the restoration of the AX2-1, the external computer 6 receives the message "FAX2-1 has been restored" via the IP 15.
Only a recovery notification to the effect is made (f).

The external computer unit 6 sends a "FA" to the telephone terminal STA2-2 for incoming call notification registered in advance.
Indicate that you have arrived at X2-1 and the time of the incoming call. "
(G) to the CPU 14 via the IP 15.
The CPU 14 having received the instruction performs the terminal control processing on the incoming call notification telephone terminal STA2-2 according to the instruction (h).

Next, the second invention will be described.

FIG. 3 is a block diagram showing an embodiment of the second invention.

In FIG. 3, the present embodiment comprises a PBX 3 and an external computer unit 7 having a database 8, and the PBX 3 has LCs 32-1 and 32-2 which interface with the STAs 4-1 4-2 and 4-3, respectively. , 32-
3 and an IP interface to the external computer unit 7
35, a SW 31 that connects the LCs 32-1, 32-2, and 32-3 to each other, and a CPU 34 that controls the entire PBX 3.

The external computer unit 7 registers in advance in the database 8 a response waiting time for an incoming call to each of the STAs 4-1, 4-2, and 4-3, and if the response waiting time is longer than the registered response waiting time. The transfer destination STA is registered in advance.

FIG. 4 is a diagram showing a processing sequence when an incoming call is received at the telephone terminal in the present embodiment.

Next, the operation of this embodiment will be described with reference to FIGS.
This will be described with reference to FIG.

When the STA4-1 makes a call connection request to the STA4-2 (a), the CPU 34 performs a call connection process, and
The “STA” is sent to the external computer unit 7 via the IP5.
4-2, there is an incoming call from the STA 4-1 "(c).

The external computer unit 7 which has received the incoming call notification immediately searches the database 8 and
The response waiting time corresponding to 2 is confirmed (d). If the response waiting time has been exceeded, an incoming call cancel instruction (e) is issued to the CPU 34 via the IP 35.

Upon receiving this instruction, the CPU 34 executes STA4-
2 is canceled (f), and the STA 4-1 is left with the call processing. Thereafter, the external computer unit 7 determines from the database 8 that the incoming connection destination of the transfer destination is STA4.
In the case of -3, the connection instruction "g. Connect the communication path between STA4-1 and STA4-3" is issued to the CPU 34 via the IP 35 (g).

The CPU 34 that has received the instruction performs the connection processing as instructed (h), and thereby the caller's ST
The incoming call control between A4-1 and STA4-3 is performed.

[0026]

As described above, the first aspect of the present invention provides the F
When there is an incoming call to the AX, after completion of the FAX reception, a notification of the incoming FAX is automatically sent to a predetermined specific telephone terminal, so that the received message by the FAX is quickly delivered to the recipient. There is an effect that can be.

As described above, the second aspect of the present invention
By automatically changing the destination when there is no answer for a certain period of time when there is an incoming call to a telephone terminal for which forwarding has not been set, the caller does not need to make a new call and can communicate efficiently. There is an effect that can be.
