VoIP works just like a regular phone with just one major difference. How the phone service is actually connecting to your business. Instead of using the telephone company's wiring, VoIP connects your phone calls directly to your business using your broadband internet connection. You still hear that familiar dial tone and make your phone calls just like you've done in the past. The big change is that you don't pay an expensive bill to use the phone company's telephone poles, switching and wiring.
