[0020] figure 1 is a schematic configuration diagram illustrating a communication system according to a first embodiment of the present invention, and reference numeral 1 designates a telephone main unit. The telephone main device 1 is connected to an application server ASV, a telephone terminal IPT, and a voice mail device VM via a local area network (LAN) 2 .

[0021] The telephone main device 1 is connected to a public network INW (such as the Internet) arranged more widely than the LAN 2 via the LAN 2 and a firewall FW, and is further connected to the maintenance device MT from the public network INW.

[0022] figure 2 It is a block diagram illustrating the functional configuration of the telephone main device 1 .

[0023] The telephone main device 1 includes an analog trunk interface unit 11 , a digital expansion telephone interface unit 12 , a timer switch 13 , a central control unit (hereinafter CPU) 14 , and a LAN interface unit 15 . The analog trunk interface unit...

[0044] Figure 6 is a sequence diagram illustrating an operation for establishing a controlled connection between the maintenance device MT and the telephone main device 1 according to the second embodiment of the present invention.

[0045] When the telephone main device 1 is remotely controlled by the maintenance device MT, the user of the maintenance device MT calls the telephone main device 1 . Therefore, the maintenance device MT creates a communication establishment request (INVITE message) to the telephone main device 1, and transmits the request to the public network INW ( Figure 6 (1)). When the telephone main device 1 returns a response (200 OK) to the request ( Figure 6 (2)), a session for notifying the connection destination is formed between the maintenance device MT and the telephone main device 1 via the firewall FW and the public network INW ( Figure 6 (3)). Information for identifying access to maintenance on the telephone main device 1 side includes an...

Abstract

The present invention provides a communication apparatus and remote control method in communication system. According to one embodiment, a communication apparatus includes a receiver which receives a Dual Tone Multi Frequency (DTMF) signal for specifying a control request is transmitted from a management apparatus, the control request including connection destination information for specifying a management apparatus, the management apparatus is connected to the public network and remotely controls the communication process; a calculator which obtains a control request from the DTMF signal; and a controller which creates a session for management using a known protocol passable through the firewall with respect to the management apparatus based on the connection destination information included in the control request, and allows the management apparatus to execute a process based on contents of the control request.

Description

technical field [0001] An embodiment of the present invention relates to a communication device remotely controlled by a management device such as a personal computer through an Internet Protocol (IP) network or a public network, and a remote control method for the communication device. Background technique [0002] The telephone switching device detects internal or external anomalies encountered during the process, and records the detection results as error / alarm log files into the built-in memory of the line / terminal connection card. When the software call / maintenance process is performed, the exchanged messages and their contents can be recorded as a log file in the built-in memory of the line / terminal connection card. [0003] When the telephone switching apparatus collects log files of line / terminal connection cards, and updates programs, controls services, and changes settings, it can normally perform these processes by connecting via a serial port or an Ethernet (regi...
