Best Skype Alternatives: How to Find Alternatives to Skype

Skype sometimes does not work ideally, so a number of alternatives are available, including the following:

Gtalk
Sight Speed
VOIP buster
VBuzzer
iChat (Mac-only)

Note that some of these are not available for all platforms, notably iChat. They're also corporate level solutions, such as Microsoft live meeting, Cisco, Tandberg, and others. HP also offers a tool called sky room, which is included with many of its workstation products; however this requires a local area network connection.
