Design and implementation of the System Based on the H.323 Protocol of the Beijing 12316 IP call

Abstract

To improve the network of Beijing 12316 voice call system and access the flexibility, enhance scalability and maintainability of the system, this paper analyzes technical advantages of the IP call system compared with the traditional voice call system, design and implement the voice call system, which is based on H.323 protocol IP on original Beijing 12316 voice call system. The system contains interface layer, traffic flow control layer and encapsulation layer, and the system is based on communication and control functions of H.323 protocol, which is invoked in the form of ActiveX controls, which can be called directly to complete the basic business functions. Users only need a computer with audio equipment or IP telephone of network to use the system, which will improve service quality of the Beijing 12316 IP call system greatly.
