Other AbstractWith the development of Internet and communication technology, VoIP, one of the extra net services, is presenting more and more application perspectives. VoIP has the advantage of price, plenty of services and the efficiency of resource utility and is becoming more and more popular. SIP (Session Initial Protocol) has the advantage of all other Internet protocols, such as simplicity, efficiency, so SIP has become the most significant calling session of VoIP. RADIUS is Remote Authentication Dial In User Service. It is one of the most popular AAA protocols for its flexibility, expandable. CentOS, Asterisk, OpenSER and FreeRADIUS are the leaders in Open Source world. CentOS is Open Source enterprise based Red Hat Linux Operation System. Asterisk is the most wide-used Open Source IPPBX. OpenSER is SIP router and FreeRADIUS is open-source RADIUS server. This article studies the SIP and RADIUS protocols and with the knowledge of these kinds of Open Source software, I proposed a relatively reasonable architecture of VoIP system. With these open source software I established the VoIP system which can authenticate, authorize and account the users’ calls along with cooperation the FreeRADIUS. Beside of this I carried out the accounting management system with PHP. The accounting management system has two main aspects, one of them is system management and the other is user self-management. I have tested the VoIP and accounting management system including the capability of management and making sure if this system can authenticate and account the users. The result of the test is optimistic. This system can perfectly handle the authentication, authorization and accounting works, and the management system can make the users easy to manage the system and query the accounting list.
