VoIP is short for Voice over Internet Protocol.

Voice over Internet Protocol is a category of hardware and software that enables people to use the Internet and LAN (private network) as the transmission medium for telephone calls by sending voice data in packets using IP rather than by traditional circuit transmissions of the PSTN.

Advantages of VoIP

One advantage of VoIP is that the telephone calls over the Internet do not incur a surcharge beyond what the user is paying for Internet access, much in the same way that the user doesn't pay for sending individual emails over the Internet.
