在網際網路語音服務上設計支援視訊會議之網頁式電話及利用自由軟體開發互動式語音應答系統

Abstract

The web-based phone is an attractive solution for VoIP users and the operators. A VoIP user only requires a web browser and an internet connection to use the services at anytime, anywhere. In this paper, freeware is used to build up a low-cost VoIP platform providing the web phone, voicecommunication, video conferencing, instant messaging and postpaid/prepaid services. An interactive voice response (IVR) is also installed to interact with the prepaid users for querying their balance and recharging. As a final remark, our system can be easily installed and established in universities, colleges and small companies with minimum cost.
