Vonage offers consumers, businesses and SOHO users the opportunity to move away from their expensive landline providers. Vonage works just like a traditional phone line except calls are made over a user's existing broadband connection. Calls are made from your home phone to any landline and mobile around the world. Users can even use their existing digital or touch tone telephone which plugs straight into your existing modem / router & Vonage adapter.
