The Design And Implementation Of Unified Communications IP-PBX Dispatch System

With the popularization of Internet and the development of global economy and technology, Enterprise's communication requirement tends to be diversified. It has been already hard for traditional PBX to meet the development mode and growth need of modern enterprises and IP PBX accords with the converging trend of NGN and can meet the communication requirements of modern enterprise. IP PBX is replacing traditional PBX and becoming the most important enterprise communication solution.The command and scheduling communication system is one of important means during coal mine safety production and management. With the maturity of NGN network, it is a future development tendency of dispatching and scheduling to achieve the voice, video, data and other multi-service can be transmitted, controlled and managed by the unified IP load bearing network in the enterprise. For realizing the voice scheduling function based on VoIP and improving the reliability, flexibility and service extension of voice scheduling communication, one dispatch system is studied and developed based on IP PBX.First, this paper provides the overview of VoIP and IP-PBX, then describes the overall design of the console software, and then designing function module of dispatch system according to feature of IP PBX and dispatching system. Finally, in view of Windows Socket, by the hierarchical module soft operation structure, the programming of dispatch system is achieved, and the call module, timer module, voice communication module and other public modules are designed and realized core scheduling function are developed and achieved on the basis.Unified Communications IP-PBX dispatch system is successfully developed in this paper, and it can be used to manage and control the calls, obtain the phones'status information, and implement call recording and monitoring functions.
