Abstract


With developing of the modern communications technology, the enterprises sustainable development depends on low cost and high efficiency. With the development of companies, more and more branches set up, all these will bring high communications costs, a large number of domestic long-distance calls, international long-distance and the use of fax, bring a heavy load and huge business spending to the company. This huge expenditure would have been accompanied with the development of company. Its importance and urgency requires companies integrate the various branches of the communications network as soon as possible to make it more efficient. With the growth of network information flow, a variety of dazzling development of Internet-based businesses come up. IP-PBX is one of them.First analyzes the background of the IP-PBX as well as development status and research and the purpose and practical significance of researching IP-PBX system. After a brief introduction of the SIP protocol, it analyzes the overall structure of IP-PBX system. System has three main modules: configuration module, terminal management and call control module. Then introduce the structure and design of terminal management module and the call control module which are the two most important modules of the system. Finally discuss the design and implementation of sevel important system features base on the modules above.
