Start a FaceTime Call from the Web
Once a user clicks on the properly formed FaceTime URL, FaceTime.app will launch in Mac OS X or iOS and a video call will be initiated. In both cases, you’re required to have a FaceTime compatible camera and the FaceTime app installed. If you don’t have it on the Mac, you can buy FaceTime for Mac for $1 from the Mac App Store (App Store link).
A link will work like this: FaceTime: OSXDaily. FYI, this URL opens a FaceTime call to our group email, feel free to try it out although I can’t guarantee anyone will answer. Maybe you’ll see this stuffed animal though:
You could take this tip a step further and combine it with setting your Mac to automatically answer FaceTime calls from specified emails and numbers.
David saw this tip on TUAW’s tips sidebar and sent it in, I couldn’t track down the URL but thanks to both for the submission and tip!
