Embodiment Construction

[0037] Please refer to FIG. 1 , which is a schematic diagram of an Internet phone system according to an embodiment of the present invention. The Internet telephone system 1 disclosed in the present invention includes an Internet telephone switchboard 10 and several Internet telephone extensions 12, which are connected by the company's internal local area network (LocalArea Network, LAN) to transmit signals, and the Internet telephone switchboard 10 can separate the internal LAN Network and the external network telephone communication protocol (Voice over Internet Protocol, VoIP) network, avoiding the situation that the extension 12 is directly connected to the external network and cannot be effectively monitored. Wherein, the switchboard 10 has a software user module 100, a monitoring module 102, a virtual sound card 104 and a system scheduling module 106; any extension 12 (the first extension 120 is used as an example below) is all connected by a wired or wireless communicati...

Abstract

The invention discloses a network telephone system and the operation method thereof. The system comprises at least: a network telephone switchboard for separating the local network from the internet, which includes a software user module, a monitoring module, a virtual sound card and a system scheduling module; and several extensions each of which connects to the switchboard through the local network for calling and answering. An incoming phone call is broadcasted after passing the protocol of the system scheduling module, when the external call is switched on, it is sent to an extension by the virtual sound card to connect and form a communication.

Description

technical field [0001] The invention relates to an Internet telephone system, in particular to an Internet telephone system capable of controlling and managing several extensions and its operating method. Background technique [0002] In today's voice communication field, Voice over Internet Protocol (VoIP) is almost an indispensable main component. The basic principle of Internet telephony is to encode and compress analog voice into digital voice signals by means of voice compression and coding / decoding, and then upload the digital voice signals to the Internet in the form of data through the Internet Protocol (Internet Protocol). [0003] Common types of VoIP communication protocols include H.323 (ITU-T Recommendation H.323), Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), and SKYPE communication protocols. Among them, the two communication protocols of SIP and SKYPE are the most common and popular. [0004] In recent years, the SKYPE communicat...
