PGPfone (Pretty Good Privacy Phone) is freeware a software package that turns your desktop or notebook computer into a secure telephone. It uses speech compression and strong cryptography protocols to give you the ability to have a real-time secure telephone conversation. Secure voice calls are supported over the Internet, or through a direct modem-to-modem connection, or even over AppleTalk networks.
