The Software Design And Implementation Of CTI Communication Client Based On TSAPI Protocol

In recent years, with the rapid development of digital communication network and increasing capacity of computer processing, the syncretiztion-speed of communication and computer technique is becoming faster and faster. As a result, CTI technique is widely applicated. We exploit the communication increment function with CTI technology in order to improve the service efficiency, and to enrich the information service,which is much important in application.There are some usually used interface protocols in CTI application development, such as TAPI, TSAPI, JTAPI. With comparison among them, combining CallCenter construction application project, the paper consider that TSAPI fulfills the requirement of the project.The paper analyzes the system architecture, network delamination mode, communication mechanism and the function of TSAPI protocol. Also the paper studies the basical application mode of TSAPI put forward by ECTF. Based on it, the CTI system scheme with Client/Server mode is designed. Solution to the technical difficulty in protocol application development is then put forward.According to practical requirement, the client communication software is designed and implemented. There are many technical key points in development, such as communication between client software and telephony server, safe receiving of TSAPI messages, synchronization setting between agent state and device state, abstraction of dialing number, realization of the application function ,etc. The paper presents the detailed solutions to these points. Software function is tested through simulation environment provided by Avaya company. The experimental results show that the scheme is successful.TSAPI protocol, a primary interface standard in CTI exploitation based onwith switch, is widely used. In this paper, the system design scheme and technical key points in application development can be supplied to relative persons as references.
