How Does VoIP Work?

Pretty much, VoIP technology replaces the phone line with a connection to the Internet, instead of using a single-purpose, ancient mainframe.

You use VoIP like you would use any other telephone — pick up the phone, wait for the dial-tone, and dial the telephone number of your choice. There are no extra numbers to dial and no special routines to follow. It's that simple.You don't have to be a tech wizard to use VoIP service; you only need to like great prices and great features.

VoIP services provided by broadband phone companies typically include many standard features with their plans that are usually listed as “advanced” by traditional phone service companies. But what is advanced and expensive for phone companies comes standard and cheap with VoIP. Some good examples of "advanced" features include Caller ID, Voicemail, and Call Forwarding.

If you want to surf the web and use your VoIP service at the same time, have no fear. You can share your Internet connection with your computer, so you can on the phone and surf the net with ease. You don't even need a new phone. With a phone-to-phone setup, most VoIP providers will provide you with an adapter to connect to the internet through your phone. You can also use your computer and a headset to make VoIP phone calls through your computer with a simple piece of software and no additional equipment.
