It is the requirement of the next generation communication systems that devices should provide all existing and future communication services in integral way. A novel distributed wireless VoIP infrastructure based on SIP protocol, WiFi, and smart devices is proposed in this paper. The proposed architecture of the infrastructure is simple, manageable, stable, and extendable. The prototype test bed is an Infrastructure of distributed wireless VoIP Server based SIP, which provides text, voice and video communication to both wired and wireless devices. One of the main characteristic of this model is roaming and mobility. User authentication is centralized, and SIP server uses remote centralized AAA server for user authentication . Thus mobile users don’t need to worry about roaming and changing the Server. The whole architecture is modular, and the reason for isolating the core modules from the extended modules is flexibility and extendibility. At the end of the paper, detailed test approaches ,test results and result analysis of the prototype system are presented. Test results show that the prototype system reach the design goal of this research work..
