Voice over Internet Protocol (VoIP)
A method for transmitting voice communications over data networks such as the internet. VoIP applications enable certain electronic devices to:
- Convert a caller's analog voice signal into digital data packets.
- Transmit the data packets over the internet to a specified recipient.
- Reassemble the data packets into the analog voice signal at the receiving end for the recipient to hear.
These devices must be connected to a data network (preferably a high-speed network) for individuals to communicate using VoIP applications. Examples of VoIP-capable devices include:
- Personal computers.
- Mobile communications devices such as cell phones, tablets, and portable media players.
- IP phones (phones with VoIP capability built in) that connect directly to the internet.
- Standard phones that connect to a special adapter.
