Wireless Enabled Voice over Internet Protocol (VoIP) Network Application Using Asterisk PBX

Abstract

This paper reechoes the need to use VOIP-based communication channels in order to reduce the heavy cost burden of communication in Sub Saharan Africa and other developing countries. We focus specifically on the context of the campus environment and implement IP PBX to cut down the cost of placing and receiving voice calls, instant messaging and voice mails with other colleagues connected to an Asterisk server on WIFI-enabled networks. We are motivated by the ease and cost-effectiveness of setting up WIFI-enabled IP network infrastructure which in recent times could be extended to allow inter-institutional linkage to allow collaboration and research.

An Algorithmic Approach to Identify the Optimum Network Architecture and WLAN Protocol for VoIP Application

“…VoIP is a mechanism for transmitting time-sensitive voice over the packet-switched network. VoIP has turned out to be a serious competitor to the traditional public switched telephone network (PSTN) [3]. However, providing precise QoS considered an issue for real-time multimedia applications such as VoIP, video over IP and online games.…”
