The people you call do not need to have a computer to communicate with you. When you pick up the phone with CallVantage and dial a phone number the phone adapter (black box) converts your voice into data and sends the data through the Internet in a similar manner to an email message. Most providers require you to have a custom telephone adapter that is pre-configured for their network so providing your own may not be an option. Be aware that some services don't work during power outages and the service provider may not offer backup power.

With normal internet protocols, you can have a network consisting of many routers (20 - 30 or more) which can result in a very high round trip time. Virtual numbers are normally an additional cost but can start out at only $4.99 per month and they can only be used for incoming calls. This technology converts the voice signal from your telephone into a digital signal that travels over the Internet.
