The Design And Implementation Of The Trunk Gateway Management System Based On Asterisk

With the development of economy and network technology, companies begin to use the call center system to communicate with customers widespreadly, providing personalized, customized high quality services, so as to achieve the purpose of improving business. A good choice of trunk gateway has important significance for the call center business expansion. According to the needs of the call center, this paper puts forward to use Asterisk as the gateway module of call center, and on this basis, completes the design and implementation of the gateway management system.This paper firstly introduces the research background, and analyses the development of the call center and a variety of advantages when Asterisk used in call center. Then it analyses the current application status of the Asterisk software, summarizes the practical significance of this subject. It is followed by the research and analysis of protocols which may be related with the Asterisk Gateway. The essence of the gateway work is protocols. Through the analysis of the format and process of the various protocols, familiar with the call setup and teardown process, it has been clear about the important role of the gateway in the call process.The design and implementation of the gateway management system in this paper mainly divided into two parts:First, builing the gateway system in the background, second, the design and implementation of the management page. In the building and testing process of gateway system, it mainly introduces the types and effects of the Asterisk gateway configuration files and significance of the parameters in the files. Then it completes the SIP/ISUP gateway and SIP/PRI gateway configuration to achieve the basic functions of the gateway. It simulates the actual network environment, using manual or automated software to complete the features, concurrency and stability testing. A large number of test data prove the good performance and feasibility of the Asterisk software as a gateway module. In the design and implementation of the management page, the page is divided into multiple modules, focusing on a detailed needs analysis for each functional module configuration items, and complete the page with the HTML language and business logic languages SLP. The next test results show that the system has successfully completed the design with friendly interface, simple operations, and achieved the simplistic and convenient management and maintenance. It has completed the design and implementation of the whole gateway management system.Finally, in this paper, the trunk gateway management system development work is summarized, and put forward the further research emphases.
