VoIP hardware and software work together to use the Internet to transmit telephone calls by sending voice data in packets using IP rather than by traditional circuit transmissions, called PSTN (Public Switched Telephone Network). The voice traffic is converted into data packets then routed over the Internet, or any IP network as normal data packets would be transmitted. When the data packets reach their destination, they are converted back to voice data again for the recipient.
