Abstract

The study reported in this article aimed to evaluate the main Quality of Service (QoS) parameters in VoIP (Voice over Internet Protocol) systems, through a practical case, quantifying the data obtained in various test scenarios to propose solutions that serve as reference in the selection of technologies to be used in VoIP system projects with IPBX (Internet Private Branch Exchange). The methodology used in terms of its nature is applied research, which allowed generating a solution to the problem in a practical way. As for the procedure, it was a practical experiment, as it allowed the manipulation of variables related to QoS parameters with network traffic analysis tools, to compare them. The approach to the problem was based on a qualitative-quantitative analysis, supported by quantifiable indicators. Despite the influence of voice compression codecs and the signalling protocol, it was found that other aspects such as bandwidth, type of connection and network equipment technology are determining factors for evaluating QoS in VoIP networks. Therefore, future studies are recommended to better evaluate the influence of these factors as well as the type of connection, QoS guarantee methods and equipment technology.
