Thirdly, it describes each functional module in detail, that is to say, it introduces the business process, the combination of various functional module through standard interfaces and the ultimate realization of the entire system through the code. In the end, it also elaborated on the software testing process as well as some improvement ideas.Through the development, integration and testing, the VoIP soft phone system has entered into a commercial trial run stage at present. It can meet the general needs of our customers, obtain the expected results, achieve prime design requirements and objectives.
