Internet telephony consists of a combination of hardware and software that enables you to

use the Internet as the transmission medium for telephone calls. For users who have free,

or fixed-price Internet access, Internet telephony software essentially provides free

telephone calls anywhere in the world. In its simplest form, PC-to-PC Internet telephony

can be as easy as hooking up a microphone to your computer and sending your voice

through a cable modem to a person who has Internet telephony software that is

compatible with yours. This basic form of Internet telephony is not without its problems,

however. Connecting this way is slower than using a traditional telephone, and the

quality of the voice transmissions is also not near the quality you would get when placing

a regular phone call.
