How VoIP Works
With Vonage, you make phone calls using your high-speed Internet connection and yourexisting home phone. Learn more about how VoIP works by watching the video below.

Vonage routes your phone calls over the Internet using Voice over Internet Protocol, rather than telephone lines. But even though your phone uses the Internet, it has nothing to do with your computer. In fact, your computer doesn't have to be on to use Vonage. The people you call don't need to have Vonage or the Internet to get your call - just a phone. And when someone calls you, your phone rings as usual.
There are many options to set up multiple phones for one Vonage line.
Cordless phone system
Some cordless phone systems come with base units and the option for extra handsets. The base station of the cordless telephone plugs directly into the Vonage phone adapter and multiple handsets can be placed anywhere in your house. The only limitation to the number of handsets you can have, depends on the number of handsets your unit supports.
Home wiring
Use your existing home telephone wiring to route Vonage service throughout your house to your existing telephones/telephone jacks. The Vonage line can support up to 5 phones. Learn More
