Currently, most of elementary schools are using closed system of tranditional telephone. However, the tranditional system is not easy to extend. It has also incurred an expensive maintaince cost. 　 　　To solve the above problems, we integrate the existing network structure with the “Elastix” (based on the open source software IP PBX) to develop a campus voice communications system (CVCS) to streamline the management of manpower and costs. The CVCS can work scalability and manage actually to run on the campus of the IP PBX system. It can reduce the external communication costs of the school. In addition, the CVCS is able to be used as an example to build IP PBX of elementary school. The Internet phone assoiciated value-added application services can be extended to various education institutions to promote the benefits of network application services.
