Descripción:

In this video, Jeremy Cioara covers how telephone systems work in general and what differentiates VoIP from the analog and digital voice systems of both the past and present. He also describes the advantages of VoIP over traditional systems and some of the real-world protocols that it uses to accomplish this. After watching this video, you will understand the basics of how voice communication works, regardless of how technical your background may be. Jeremy will teach you how voices travel from one device to another and how analog, digital and VoIP systems make this happen in very different ways by converting voices into either electronic impulses or data prior to transmitting them over cables. You will further learn how VoIP uses TCP/IP and various special codecs that are unavailable in analog and digital systems to make voice communication more efficient and easier as well as compatible with a wide range of devices.
