VoIP technology works if you have a broadband connection and a device called a router. 
The router allows the phone to ring, just as it always has been, but now it's the broadband digital connection instead of through a normal telephone line. In addition to a router is a VoIP gateway that connects you to a voice over the net, so your voice can be converted to a digital sound instead of using analog technology of the past. Information is basically sent in packets across broadband lines to give a great sound and seamless connection to those who have VoIP service and even those who do not. VoIP is really a revolution that combine Internet access and telephony because it uses the same technology for two very different things.
VoIP is great because now you can have just one bill, which allows you to access phone and broadband connection. Fortunately, most companies even allow you to be online at the same time as you are on the phone. There are really no restrictions on VoIP service and in future it will only get easier. In the coming years digital phones will be made so that each consumer will not have a router, and VoIP service will probably be more common than those that have a public telephone. If you already have a broadband connection, you should definitely consider a VoIP phone connection because it is most cost-effective, practical, and it really is the way telephone and internet service is started!
