VoIP service provider

A voice over Internet Protocol (VoIP) service provider offers VoIP Internet telephony solutions to residential and commercial customers. Also known as an Internet phone service provider, a VoIP service provider generally provides the VoIP hardware and services to subscribers at a monthly rate, although hosted VoIP services are also quite common.

As with all VoIP solutions, VoIP service providers utilize packet-switched telephony to transmit calls over the Internet as opposed to the circuit-switched telephony used by the traditional Public Switched Telephone Network (PSTN). VoIP calls are like regular phone calls but they're made over a broadband high speed Internet connection rather than over a regular telephone line.

The key advantage to VoIP phone calls is that unlike regular long-distance calls, calls made through a VoIP service provider are free – there are no fees beyond the cost of your Internet access.
