Abstract

PURPOSE:To transfer an incoming call to a desired transfer destination automatically when the incoming call comes to a terminal equipment during transfer setting. CONSTITUTION:When a STA1 makes transmission connection (b) to a STA2, a CPU 7 makes no incoming call connection processing and makes incoming call notice (c) from the STA2 to the STA1 to a computer 9 via an information channel 8 leaves an exchange processing instruction to the computer. The computer 9 receiving the notice retrieves immediately a database 10 to confirm a time zone dependent connection destination incoming call number list corresponding to the STA2 (d). When an incoming call connection destination of the time zone A is a STA 3, the connection of a channel 5 between the STA 1 and STA 3 via the information channel 8 (e) is instructed and when the incoming call connection destination for a time zone B is STA4, the connection of the channel 6 between the STA1 and STA4 is instructed (f). The CPU 7 receiving the instruction makes connection processing according to the instruction, then the transfer destination of the STA 2 is revised by the time zone.

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.
In particular, it relates to a transfer control method.

[0002]

2. Description of the Related Art A conventional transfer control method unconditionally transfers all incoming calls to a transfer-set terminal to a specific terminal (transfer-destination terminal) by internal processing of an exchange. There was no method to transfer the incoming call by changing the destination depending on the time zone.

[0003]

In this conventional transfer method, all the incoming calls to the terminal for which transfer is set are unconditionally transferred to the specific terminal. Therefore, for example, it is necessary to use the terminal to specify the transfer destination for each time zone. However, even if there was a request from the person in charge, the request to transfer the incoming call to the specific terminal could not be dealt with.

An object of the present invention is to provide a transfer control system for transferring an incoming call to a desired transfer destination registered in advance for each time period.

[0005]

The transfer control method of the present invention is a storage program type private branch exchange having a communication control interface from an external computer, and is used for a telephone terminal set to transfer in the private branch exchange. When there is an incoming call, means for notifying the external computer of the information of the incoming call, and the external computer receiving this incoming call information, the pre-registered time zone connection destination called number list is inspected Means for reading out transfer setting information corresponding to the receiving terminal and collating with the incoming call information; means for instructing the private branch exchange based on the result of this collation; and means for performing connection processing in accordance with the instruction for transfer destination. Have.

[0006]

The present invention will be described below with reference to the drawings.

FIG. 1 is a relay system diagram showing an embodiment of the present invention, and FIG. 2 is a processing sequence diagram of this embodiment. In FIG. 1, the exchange is a time divisional switch 11 and a control CPU.
7 and accommodates extension terminals (STAs) 1, 2, 3, and 4. The control CPU 7 is functionally coupled to the external computer 9 via the information communication path 8. It is assumed that in the database 10 of the external computer 9, partner number information (a time-zone connection destination call number list) that permits incoming calls without performing transfer control for each extension terminal accommodated in the exchange.

Next, an operation example will be described with reference to FIG. ST
A2 first desires the transfer connection control of the present invention, performs a predetermined input operation (eg, pressing a function button), and then the CPU
7 recognizes this transfer setting (a). After this, STA1
When the STA2 makes an outgoing call connection to the STA2 (b), the CPU 7 does not perform the incoming call connection process, but only notifies the computer 9 via the information communication path 8 that the STA2 has received the incoming call from the STA1 (c). , Exchange instructions are given to the computer. Upon receipt of this notification, the computer 9 immediately searches the database 10 and confirms the STA2-compatible time zone connection destination called number list (d). As a result, for example, if the incoming call destination of the time zone A is STA3, the connection of the call path 5 of the STA1 and STA3 is instructed via the information communication path 8 (e), and the incoming call destination of the time zone B is STA4. If so, it instructs the connection of the communication path 6 of STA1 and STA4 (f). The CPU 7 that has received the instruction in this way can change the transfer destination of the STA 2 for each time period by performing the connection process as instructed.

[0009]

As described above, according to the present invention, since the transfer connection destination can be freely selected for each time zone, when there is an incoming call to the terminal for which transfer is set, the call is received at the desired transfer destination. There is an effect that the call can be automatically transferred.

Claims (1)

Claim: What is claimed is: 1. In a store program type private branch exchange having a communication control interface from an external computer, when a call is received by a telephone terminal set up for transfer accommodated in the private branch exchange. And a means for notifying the external computer of the information of the incoming call, and a transfer setting corresponding to the incoming terminal by probing a pre-registered list of connection destination called numbers on the external computer which received the incoming call information. The transfer setting includes means for reading out information and collating with the incoming call information, means for instructing the private branch exchange based on the result of this collation, and means for performing connection processing in accordance with this transfer connection destination instruction. A transfer control method characterized in that the hour telephone terminal can specify the destination by the time zone.
