Embodiment Construction

[0050] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0051] 1) Construction of Asterisk SIP server:

[0052] The present invention uses Asterisk software to realize the SIP server. Asterisk is an open source software running on the Linux operating system, which enables communication between circuit-switched telecommunications network equipment and packet-switched data network equipment. Connect the analog phone to the analog interface board of the SIP server through the telephone line, and connect the SIP server to the local area network. In this way, the network user can register to the SIP server through the local area network, so as to communicate with other network users or analog phone users. First, install the Asterisk software on the Linux operating system. After installing Asterisk, configure it, that is, modify the contents of the two configuration files sip.conf and zaptel.conf, create accoun...

Abstract

The invention provides a VoIP communication system based on an SIP protocol and a communication method thereof. The system comprises a user interface module, a main state control module and a communication management module, the main state control module is respectively in communication linkage with the user interface module and the communication management module, and the communication management module also comprises a network initialization module, a call control module, a network message monitoring module and a cancellation module. The invention further provides a communication method based on the communication system so that the VoIP communication system based on the SIP protocol in the invention is mounted at an intelligent terminal and connected with a Web server, an MySql server and an Asterisk server mutually through a network, so as to realize the organic integration of the services, such as intelligent speech synthesis recognition, multi-protocol instant messages, short messages, Email and the like, in the same network.

Description

technical field [0001] The invention relates to an application of VoIP technology in the field of converged communication, in particular to a VoIP voice service running on an intelligent terminal. Background technique [0002] For a long time, people have been paying attention to how to carry out long-distance voice communication. In the past 100 years, we have all relied on the public telephone network PSTN (Public switched Telephone Network) for voice communication. When two places talk, there is a fixed line allocated to both sides of the conversation. Although there may be redundant bandwidth in this line, other information cannot be transmitted at the same time. When data communication services appear, this communication method based on circuit switching gradually exposes its defects of low resource utilization efficiency and reliability. [0003] Not only that, the emergence of voice and data integrated services has also put forward higher requirements for traditiona...
