Study Of IP-PBX System Based On Soft-Switch Technology

The telephone switching technology was developed based on the circled switching principle from long time ago. Integrated communication requirement of enterprise becomes more and more urgent with the development of the social economy's development, PBX, based on the traditional switching technology, can not meet the requirement of the modern enterprise's global development. Soft switching IP-PBX theory and technology is concerned in recent years. As a very important way to solve the communication combination problem, soft switching IP-PBX development has very large market value, but it still on the first stage internal.This is a research article based on the technological conclusion and related theory analysis of soft switching IP-PBX project which the author took part in. The author is in charge of project design, main protocol and technology of soft switching application research in this project. The article provided a soft switching project Concerned on the soft switching principle and pivotal technology application research, based on analyzing, discussing the history, development and its status quo, provided a soft switching project that is suitable for middle small-scale users by the deeply analysis and research. This is a system combined by circuits switching and IP switching, adopting modularization and hierarchy, with stronger compatibility and expansibility. The author designed the whole project of soft switching IP-PBX system, dissertated the design means and implement of IP-PBX core soft switching and media network in detail, deeply analyze and study of IP-PBX bear-network.At last, the article proves technology theory, design plan and implements of this project by testing and analyzing of the experiment system. This research production would become availability technology accumulation of industry. And the project would provide economic benefits in future if given more development.
