Using native virtualization technologies for teaching IP telephony to future IT specialists

Abstract

This paper explores the use of virtualization technologies for teaching IP telephony to future IT specialists. It defines the requirements for students’ professional training in this field and identifies the components of a network training laboratory for IP telephony. It also analyzes the modern approaches to virtualization technologies and their advantages for learning IP telephony. The paper proposes native virtualization as a suitable solution for creating a virtual training laboratory using VirtualBox software. It reports the results of a pedagogical experiment that confirmed the effectiveness of the developed virtual laboratory and repository of virtual hosts for teaching IP telephony. The paper highlights the benefits of virtual machines for student mobility and remote learning,especially during the pandemic and war.
