Overview

VoIP University is a solution to enable the development of communication projects based on IP protocol. This paper presents a low-cost deployment called VoIP UEMA, the first project of VoIP University solution. The technical feasibility of this project was checked as proof of concept. The concept was proven showing it is possible to create user extensions with some information such as name, ID, job role, course, center, and campus getting information of all registered users in the academic and administration system server to make voice and video calls through Android application and browser web phone. A mean opinion score test that measures subjective voice quality for a call was done with 35 people calling each other using two VoIP UEMA softphones, VoIP UEMA application, and VoIP UEMA web phone. The result achieved a weighted average of 3.5, indicating good-quality calls. The low-cost aspect was justified by a financial analysis showing the annual phone bill expenses dropped, representing savings of over 97 %.
