Abstract

PURPOSE: To perform control from a terminal device of a local data system network by sending control indications to a switching controller according to control indications of the switching controller received from a data terminal device and a telephone system file. CONSTITUTION: The dial number sent by an external terminal device 14 is received by a data terminal communication control part 4 through a line switching part 3 and reported to a server 21. In the server 21, a receiving process means 24 decides that the received dial number is that of a terminal device 30 by referring to a correspondence table of extension numbers and data terminal devices 30 to 32 and the telephone system file 25. Then the receiving process means 24 selects the data terminal device 1 and displays a screen. Further, the server 21 informs the control part 4 of a connection command for the line of the telephone terminal devices 11 to 13 and external device device 14. At this time, the control part 4 controls the line switching part 3 to connect an analog terminal device 1 to the terminal device 14. Then the switching controller can be controlled from the terminal device 1 of the local data network system.

(2) The user activates the telephone system program (main application program) of the present invention of the data terminal device. (3) The data terminal device notifies the server of its extension number.

(4) When the PBX notifies the server of an incoming call, the server refers to the extension number file (data terminal management DB) of the telephone system file and obtains the extension number and connection ID (connection handle ID). .

(5) Notify the destination extension number to the PBX,
Request connection processing. (6) The server refers to the extension number file and notifies the data terminal device of the connection ID corresponding to the extension. Then, the screen switching process is performed in the data terminal device.

FIG. 18 is an explanatory diagram of PBX and server startup processing. In FIG. 18, reference numeral 51 is a PBX (exchange control device).

Reference numeral 60 is a server. Reference numeral 89 denotes a main application program, which is an application program for performing main control of the communication system.

Reference numeral 83 is an exchange control unit communication control program. Reference numeral 90 is a call state transition notification table in which extension numbers (extension numbers to which the present communication system is applied) that need to be notified of call states such as busy and ringing are registered.

Reference numeral 95 denotes a data structure of event information, which is created each time an event such as an incoming call occurs from the PBX 51 to the extension number registered in the call state transition notification table 90. Event I indicating the type of event
D, call I created to identify each communication
D, extension number 1 of communication target, extension number 2 (including extension number), block number of client management table, and the like.

The operation of the configuration of FIG. 18 will be described. A logical path for communication is set between the main application program 89 and the exchange control unit communication control program 83 (a common communication code is defined). After that, this logical path is used to communicate with the PBX 51 (A
Setting PI points).

A communication path (physical bus) is established between the server 60 and the PBX 51 (TCSI path establishment). In order to receive that the main application program 89 has arrived at the extension, the extension number for notifying the call state is registered in the call state transition notification table 90 of the PBX 51 (the extension number registered when starting the communication system is updated. ).

After that, when an event such as an incoming call or an outgoing call occurs at the registered extension number, the PBX 51 notifies the server 60 of the call status, and a data structure 95 of event information is created in the memory of the server 60.

When there is a transfer processing request from the client,
A call processing transfer request is issued to the PBX based on the client management block number of the event information and the call ID. The call ID is a common management ID of the PBX and the server, and a call can be specified by designating the call ID.

According to the present invention, it is possible to control a switching control device for connecting a telephone terminal device from a data terminal device of a data network such as a LAN. It becomes possible to dial from the data terminal device to the external telephone terminal device with the corresponding extension number, and various telephone processing can be performed from the data terminal device such as LAN. Further, an incoming call notification to the telephone terminal device is displayed on the data terminal device of the data network, and the destination can be confirmed on the screen. Therefore, according to the present invention, the data network can be used efficiently.
