This paper summarizes the existing literature review for VoIP, and proposes a hypothesis that voice communications are independent of network infrastructures and hardware/software configurations between two operational wireless local area networks (WLAN). In order to verify this hypothesis, two different types of wireless networks, routers, and voice services were established and the voice communications were carefully experimented and thoroughly tested. As a result of the quality engineering process, the hypothesis is fully supported by the experimental results and voice communications are independent of wireless infrastructures and services providers, but prolong calls are likely to be affected by the locations. Before achieving this conclusion, the four major Voice Service Providers were also carefully examined and evaluated, the summary of which can provide non-biased references worthy for a large number of European and Global users.
