How does video conferencing work?
Video conferencing uses VoIP – Voice over Internet Protocol, which allows video calls to take place over the internet by converting analogue voice signals to digital signals that can be sent over the internet. Traditional telephone systems, on the other hand, use analogue lines and a series of exchanges (physical switchboxes) to carry voice signals. Through this two-way passage of digital signal, video conferencing allows for interaction between two or more people across the world.
