Voice over IP (VoIP) alows voice to be transmitted using TCP/IP protocols, usually over the internet. In the context of Amateur radio, there's usually a radio on one end of this somewhere. VoIP can be used to connect users without radios, a user without a radio and a radio without a user, or even two radios. The radios can be VHF, UHF, or even HF.

One of the reason these technologies are so popular for amateur radio operators is because it lets licensed technician class operators talk around the world without having an HF license. It is also handy to check into club Nets when out of town.
