Abstract

PURPOSE:To attain incoming call processing to an incoming call from a desired outgoing number by comparing and classifying outgoing number information detected from an ISDN with an outgoing classification information stored in a memory and executing incoming call processing to an extension terminal equipment corresponding to the decided classification. CONSTITUTION:A CPU 2 of a private branch of exchange 1 monitors an incoming call from a trunk line 6 via a trunk line interface 5 and discriminates the presence of an outgoing number included in the incoming call information when the incoming call is detected. As a result, when no outgoing number exists, a telephone set 8 connected to a specific extension corresponding to the trunk line 6 is designated to start a telephone set interface 7. Then an incoming tone is sent to the telephone set 8 to execute the usual incoming call processing. When an outgoing number exists, an outgoing number included in the incoming information is extracted and the extracted outgoing number and the outgoing number classification information in the outgoing number classification memory 3 set by the user in advance are compared and classified and the corresponding extension number is decided. Then the usual incoming processing is executed to a telephone set 8 corresponding to the decided extension number.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a private branch exchange device connected to an 15DN.

[Conventional technology] Conventionally, in this type of device, the network (ISDN network)
When receiving a call from , if the calling number (calling subaddress information) included in the call information (call setup message) is detected,
An extension terminal connected to an extension, such as a telephone, displays the calling number on its display.

[Problem to be Solved by the Invention 1] However, in the above-mentioned conventional example, only the calling number was displayed on the telephone, and the ringtone was unconditionally sounded on the telephone.

For this reason, even if the incoming call is a mistaken call or a prank call, the person receiving the call must make the decision, and the other party cannot recognize the phone number just by looking at the displayed phone number.
It was only after the incoming call was answered that the person on the other end could be recognized, which caused people to unnecessarily interfere with the call.

The present invention was made to solve the above problems, and
It is an object of the present invention to provide a private branch exchange device that can perform incoming call processing for incoming calls from a desired calling number.

[Means for Solving the Problems] In order to achieve the above object, a private branch exchange device of the present invention has the following configuration. That is, in a private branch exchange device that is connected to an 15DN and performs connection exchange of lines accommodated, there is a detecting means for detecting incoming call information including calling number information from the rsDN, and a memo and a detecting means for detecting incoming call information including calling number information from the rsDN. The apparatus includes a comparison classification means for comparing and classifying the calling number classification information stored in the caller number classification information, and an execution means for executing incoming call processing on the extension terminal corresponding to the classification determined by the comparison and classification means.

[Operation] In the above configuration, when incoming call information including calling number information from the 15DN is detected, the detected calling number information is compared and classified with the calling number classification information stored in the memory, and the extension terminal corresponding to the determined classification is It operates to perform incoming call processing.

[Embodiment] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

<Description of Configuration (FIG. 1)> FIG. 1 is a diagram showing the configuration of the apparatus in this embodiment. In the figure, 1 is a private branch exchange device, 2 is a control unit that controls the entire device, and a CPU that controls each part, which will be described later.
It is composed of a ROM that stores processing procedures (programs) to be executed by the CPU, a RAM that includes buffers, tables, etc. used by the CPtJ when executing processing, and its peripheral circuits. 3 is a calling number classification memory that stores preset calling number classification information, 4 is a switch network that connects the communication path between station II 6 and telephone tII 8 or telephone @ 8 accommodated in this device 1, and 5 is a central office line. A central office line interface for detecting incoming calls from the telephone 6 or transmitting a dial to the central office line 6, 6 a central office line to accommodate, a telephone interface 7 for detecting dialing from the telephone 8 or transmitting a ring tone etc. to the telephone 8, , 8 is a telephone connected to the extension.

<Explanation of processing procedure (Fig. 2)> Next, the control unit 2 of the private branch exchange device 1 in this embodiment (
The processing procedure executed by the CPU will be described below with reference to the flowchart shown in FIG.

First, in step S1, an incoming call from the central office line 6 is monitored via the central office line interface 5. When an incoming call is detected, the process proceeds to step S2, and the central office line interface 5
The presence or absence of the calling number included in the incoming call information (call setting message) received via the call center is determined. As a result, if there is no calling number, the process advances to step S6, where the telephone 8 connected to a specific extension corresponding to the terminating office line 6 is assumed and the telephone interface 7 is activated. Then, a ringtone is sent to the telephone set 8, and normal incoming call processing is executed. However, if there is a calling number, the process advances to step S3, and the calling number included in the incoming call information is extracted.

Next, in step S4, the retrieved calling number is compared and classified with the calling number classification information in the calling number classification memory 3 set in advance by the user, and the corresponding extension number is determined. Next, in step S5, normal incoming call processing is executed on the telephone set 8 corresponding to the determined extension number. In this process, for example, if a telephone 8 is set to ring for each incoming call, the telephone 8 is designated, the telephone interface 7 is activated, and a ringtone is sent out.

After that, the response from the telephone 8 is sent to the telephone interface 7.
When detected via the telephone, it stops sending out the ring tone, outputs an instruction to the switch network 4 to connect the communication path between the receiving station line 6 and the telephone set 8, and shifts to a communication state.

FIG. 3 is a diagram showing the configuration of the calling number classification memory 3. In the figure, 30 is an area for registering the calling number;
Reference numeral 31 is an area for registering an extension number corresponding to the calling number 30 to be ringed for incoming calls.

Further, in this embodiment, the time required for comparison classification is shortened by adopting a format in which the messages are sorted by the maximum caller number as shown in the figure.

As explained above, according to this embodiment, when a call is received from a desired party, the corresponding extension telephone can be made to ring based on the preset correspondence table between calling number (telephone number) and extension number. . As a result, the inconvenience of having a specific person respond and forward the message to a third party is eliminated.

In the above-described embodiment, one telephone extension rings in response to the calling number in the incoming call information, but it is also possible to create a group of multiple telephone extensions and have that group ring. .

Further, in this embodiment, a telephone is used as an example of an extension terminal connected to an extension, but the same effect can be obtained with a facsimile machine having a display section.
