摘要

The Wi-Fi, also known as 802.11b, has become the preferred technology for wireless local area networking in both business and home environments. Even though it was designed primarily for private applications, Wi-Fi is also being deployed in public places to create so-called hotspots, where Wi-Fi-capable users can obtain internet access. This new domain of application could be the major future market opportunity for Wi-Fi, but in order to take advantage of it, several key challenges, both technical and business-related, must be overcome. Today the most cost effective use of Wi-Fi is calling over network. We have various facilities today such as Skype, T-Mobile, T-pad, Jaxtr for communicating over network but some restriction are placed on such system like Skype support only pc to pc calling for cellular and landline call this free service become paid. T mobile also follo ws the same problem. Hence to overco me such issue we are developing a system which allows free calling over Wi-Fi network using VoIP service. Our system allows peer to peer calling and an additional feature of group calling. For supporting group calling feature we are using SIP (Session Initiation Protocol). This technology will help us to find a way for free calling and thus ultimately helps to private organization for reducing bills over communication. In this paper, the system w ill be implemented as well as the performance will be tested by doing actual i mplementation of this system
