Abstract
VoIP is a technology that is popular all over theworld for its cost effectiveness. Asterisk is an open source,converged telephony platform that supports all the protocols ofvoip (sip, iax, h.323, mgcpetc). We establish this voip basedasterisk pbx on ubuntu 11.10 (a linux-based os) which allow usto make unlimited free calls with the help of ip phone ortraditional phone within a lan/can without internet connection.Wi-fi is often presented as a model of successful unlicensedfrequency spectrum deployment. For wireless communication,we extend our voip based pbx to wi-fi technology, with the namevowi-fi. The convergence time depend on the speech content e.g.voiced/unvoiced. In terms of unvoiced segments, theconvergence time is stable as in voiced phases it fluctuates. It isalso rely on silence suppression. But it associate degree bound atthe top of the segment. As most of the internet subscribers ofAsian countries use very low internet bandwidth. Hence, thegoal of this analysis is to propose to use it without internet. In areal life environment it is tested practically in research that it ispossible to transmit voice satisfactorily described in this paper.
