How Does VoIP Work?
VoIP, or Voice over Internet Protocol, is a way of converting audio signals (like what you hear when you talk on the phone) into digital data that can be transmitted and received over the Internet. This isn’t a new technology, but rather has been in use for years by businesses and consumers … so it’s proven and reliable when setup correctly.
For a business, this allows the phone data to share much of the same equipment and Internet services you already have in place for normal Web and Internet use. It also allows you to have your phone system extended to remote sites and mobile workers – practically anywhere you have a reliable Internet connection.
When the VoIP phone calls go across the Internet, they hand off to other phone services through gateways (think cellular phone services, plain old analog lines, etc.). So a VoIP system can be used to make and receive calls with any other type of phone, anywhere in the world.
