Abstract

Nowadays, the improvement of technology make the central PBX (Private Branchexchange) has developed into an IPPBX (Internet Protocol � PBX). It because the IP-PBX has many function than the PBX. IP-PBX supports VoIP application, so clients can use a digital phone (soft phone) such as IP phones or mobile phones that have free wi-fi. That�s why it is easy to supervise and more efficient. In this final project, made a VoIP server that is embedded into access point using OpenWrt firmware and Asterisk application. So, client can use digital telephone (softphone) such IP phone and mobile phone that w-ifi supported. The result of Quality of Service observation is depend on several parameters, including the measurements of clients communication, the comparison between wireless network and wire line network, the distance comparison, the MOS calculation also the using of memory resources. Overall, the best value in VoIP communication using embedded wireless IP-PBX base 802.11 is the access point ability when it can serve 16 clients with delay value is 20,89 ms ; jitter with 6,259 ms ; packet loss is 3,675% and throughput with 80,112 kbps.
