"One of the relatively unsung features of iOS 7 is the addition of audio-only calling to FaceTime. Why would you want to use FaceTime to make audio-only calls instead of using the full video/audio capability? Well, maybe you just woke up and look like something the cat dragged in, and you don't want the person on the receiving end of the call to die of fright. Or perhaps you're using a weak Wi-Fi connection with your non-GSM iPad mini or iPod touch in an internet caf&amp;eacute; overseas and don't want to risk not being able to make a FaceTime call at all. Either way, audio-only FaceTime calling is easy to do, and today's video tip will show you how."^^<http://www.w3.org/2001/XMLSchema#string>
