VoIP has been around since the turn of the century. The protocol signified a shift in telecommunication, which happens over and over again as our technology progresses (think of the 20th century).

Skype is a free VoIP service for instant messaging, audio chat, video chat, and conferencing. There are also paid versions of Skype, by which users can contact non-Skype numbers and phones.

Like all VoIP, Skype is very dependent on users' Internet connections. In conference calls, lag can cause bursts of sound, sound interruption, call drops, etc.
