Implementation and testing of an IP PBX using raspberry pi

Abstract

In a scenario where there is a reduced number of IP telephony users, there are several alternatives to provide the service in such a way that it is not incurred in the underutilization of resources. One of those alternatives is to use as server, a cheap computer like raspberry pi, which has the advantage of presenting low power consumption. This article shows the procedure, and results, of a performance test made to a IP telephony server, which has an IP PBX functionality, using as platform the raspberry pi model B. such test aims to determine the basic features taking into account aspects like: power consumption and quality of service. As a result, the alternative presented in this article, is a good option in scenarios where it is enough to have a server with capacity for 7 concurrent calls.
