Resumo

In the recent years, VoIP and SIP based calling has been emerging as a new innovation and a master technology in reducing all over cost of communication and secure calling among various MNCs and other management based calling centres. Voice over Wi-Fi (VoWi-Fi) emerged after voice over IP (VoIP) and manifests to be a useful technology. It acts as a substitute to usual coaxial cable phone system. The purpose of this research is to design and implement a telephony program that uses Wi-Fi in an end to end link or WLAN (Wireless Local Area Network) as a means of communication between mobile phones at zero cost. The breakthrough in VoWi-Fi may severely alter the cell phone business in the upcoming future due to its lower cost, flexibility and portability. We have briefly discussed on each aspect including, virtualization, SIP, CentOS, softphones and Wi-Fi which are very much engaged in designing the layout as well as in implementation of the idea behind this research. We have also given the future prospects of VoWiFi and its deployment in the various companies.  Cite this Article Shubham Chowdhry, Ravi Jaitly, Shrish Bajpai. Voice over Wi-Fi Employing SIP.
