It consisted of a Computer, Special Software, a Sound Card, and a Microphone. In 1996, software called Vocal Tec Internet phone provided VoIP along with voice mail and Caller ID. VoIP is now becoming a standard technology in the business world. How VoIP works? : How VoIP works? Continuously sample audio. Convert each sample to digital form. Send digitized stream across Internet in packets. Convert the stream back to analog for playback. PCM(Pulse code modulation) VoIP: Packet switching : VoIP: Packet switching The data packets flow through a random network along thousands of possible paths. This is called packet switching.
