Facetime allows video calls for iOS. Facetime-Audio, added in iOS 7, allows audio only calls. The audio version uses a vulnerable URL scheme which is not used by Facetime Video. The URL Scheme used for Facetime-Audio allows a website to establish a Facetime-audio call to the attacker's account, revealing the phone number or email address of the user browsing the site. This was fixed in iOS 7.1.
