Laboratorios de telefonía IP : Prácticas de laboratorio aplicadas a telefonía IP usando Freepbx.

Abstract

Telecommunications have evolved in an incredible way in the business sector, all thanks to technological development worldwide. Companies have been persuaded to establish loyalty, effectiveness and efficiency at the level of communications with their customers. Therefore, communications systems have been implemented that allow to meet the demands of users. If we talk about a communications system at the telephony level, we can refer to an open-source VoIP telephone exchange (Freepbx), whose function is to transport conversations over IP and provide assistance to the user through a set of applications offered by the telephone exchange. VoIP telephone exchanges are in great demand in companies of all levels and in professionals who offer solutions at the telephony level. With this we want to emphasize the importance of the students of the Telecommunications Engineering career are trained in the operation and implementation of a VoIP telephone exchange. This component proposes a set of practices or laboratory guides developed in the Notion program; these laboratories are focused on the creation of a VoIP telephone exchange through Freepbx from scratch. Each session contains the most basic aspects up to highly complex parameters that are of vital importance in the administration of a telephone exchange. Through a set of six laboratory practices it is intended that the students of the Escuela Politécnica Nacional, particularly of the Telecommunications Engineering career is familiar with a real business environment on the implementation, configuration and operation of a VoIP telephone exchange. Within the laboratories there is a proposed activity that aims to evaluate and complement the theoretical-practical knowledge acquired in the session. This component has six laboratories elaborated in detail as a final product, as well as the development of the activities proposed for the students.
