Voice Over Internet Protocol (VOiP) is a type of service that allows people to call other people over the internet protocol, without the use of traditional land-line connections. Because VOiP works on global and local levels, it’s perfect for individuals and businesses who need a virtual phone number, as well as cost reduction when it comes to sustaining these numbers.
The way VOiP works is that it uses the internet connection to convert a phone signal into a digital signal, sending it over an internet connection the same way you would send an email or anything else. VOiP providers are able to give you a custom phone number (one of the reasons pranksters like to use VOiP) and you can also select the location you want the phone number to appear in. Other than that, VOiP is still as vulnerable to power cuts and outages as any other form of communication would be.
