What You Need

1. VoIP Phone Service (Vonage or Time Warner Cable)
2. Broadband Internet Connection

VoIP (Voice over Internet Protocol) is simply the transmission of voice traffic over IP-based networks.

The Economics of VoIP
VoIP has become popular largely because of the cost advantages to consumers over traditional telepone networks. Most Americans pay a flat monthly fee for local telephone calls and a per-minute charge for long-distance calls.

VoIP calls can be placed across the Internet. Most Internet connections are charged using a flat monthly fee structure. Using the Internet connection for both data traffic and voice calls can allow consumers to get rid of one monthly payment. In addition, VoIP plans do not charge a per-minute fee for long distance.

For International calling, the monetary savings to the consumer from switching to VoIP technology can be enormous.
