With the packet exchange principle,IPPBX can realize the functions of the traditional PBX on Ethernet and overcome the insufficiency of traditional PBX effectively. It has powerful functions,comprehensive services with less cost. The typical networking mode of IPPBX is introduced in this paper. The design principles of each module system MPC8250 hardware system based on IPPBX and the software system of the system are given. The protocol conversion software of main con?trol module is also analyzed. The test result shows that the system can achieve simultaneous processing of 200 calls and its voice quality is excellent.
