Voice over Internet Protocol refers to the standards that facilitate voice-based phone calls using an internet connection instead of a local telephone company.
Voice over IP converts your voice into a digital signal, compresses it, and sends it over the internet. A VoIP service provider sets up the call between all participants. On the receiving end, the digital data is then uncompressed into the sound that you hear through your handset or speakerphone.
