- Just go to http://www.facebook.com/videocalling
- Get Started
- See this. You will need to download and install something on your computer.And calls are just one on one (Unlike Google Huddle which can have upto ten people and also doesnot need any installer -esp if you use Chrome)
- Send a video message if your friend is not available. (that beats Google Huddle which doesnot seem to have the video inbox feature yet)
