The world of telephony is undergoing a drastic transition, from classic phone technology to voice over internet protocol (VoIP). The underlying technology behind VoIP phone calls is technically complicated. However, if you’re able to understand how it works from a high level, it’s easy to see the benefits. You will be able to find out why VoIP is better for your business.

Business Telephony Before VoIPPhones are great because they take human voice, convert it into electrical signals, transmit those electrical signals at near light-speed over vast distances, and revert them back into intelligible voice. It makes nearly instant communication possible despite remote locations and vast distances. But as recently as 15 years ago, long-distance calls were very expensive. That’s because your voice was traveling through a network of copper wires. During these analog telephone calls, your voice was traveling through a switched telephone network. When you were on the phone, the wires transmitting your call were dedicated exclusively to your conversation. For example, when you called someone long distance in New York from Los Angeles, you were essentially “renting” 2,000 miles of wiring. Competition for these wires let phone companies drive up the cost of long-distance phone calls.
How VoIP WorksVoIP uses the “everywhere, all the time” potential of internet protocol to achieve the same end result, albeit in a different way. When you speak into your computer’s microphone, your voice is detected as physical sound waves and converted into an electrical signal using a piece of hardware called a driver. Then, pieces of software known as voice codecs (coder-decoders) convert this electrical signal into binary data. From here, your operating system separates binary data into smaller pieces of information known as packets. These packets of audio information are transmitted…
- from your computer
- via the router
- through copper or fiber optic cables
- across the world to another computer
- reverse processed via that computer’s code
