Configuration of Own PBX System within a Campus Area Network and Implementation of VoWi-Fi

Md. Nahid Akter Shafi and Abdullah Al Kawser
Abstract—VoIP is a technology that is popular all over the world for its cost effectiveness. Asterisk is an open source, converged telephony platform that supports all the protocols of voip (sip, iax, h.323, mgcpetc). We establish this voip based asterisk pbx on ubuntu 11.10 (a linux-based os) which allow us to make unlimited free calls with the help of ip phone or traditional phone within a lan/can without internet connection. Wi-fi is often presented as a model of successful unlicensed frequency spectrum deployment. For wireless communication, we extend our voip based pbx to wi-fi technology, with the name vowi-fi. The convergence time depend on the speech content e.g. voiced/unvoiced. In terms of unvoiced segments, the convergence time is stable as in voiced phases it fluctuates. It is also rely on silence suppression. But it associate degree bound at the top of the segment. As most of the internet subscribers of Asian countries use very low internet bandwidth. Hence, the goal of this analysis is to propose to use it without internet. In a real life environment it is tested practically in research that it is possible to transmit voice satisfactorily described in this paper.

Index Terms—VoIP, asterisk PBX, Wi-Fi, IP phone, VoWi-Fi.
