Skype

http://www.skype.com/

A proprietary protocol VOIP system built using Peer-to-peer (P2P) techniques.
Free for non commercial use when using softphones (PC to PC).
Offers toll access to PSTN via SkypeOut and SkypeIn
From the company that created KaZaA

Licenses the Global IP Sound VoiceEngine suite of codecs and related software including their wideband codecs (double the width of regular pstn.) If you find yourself asking, "why does Skype sound so good?", the answer is primarily this wideband ability.
