'''FaceTime''' is a [[video calling]] software application and related protocol developed by [[Apple Inc.|Apple]] for supported mobile devices running the [[IOS (Apple)|iOS]], in addition to Macintosh computers running [[Mac OS X Snow Leopard|Mac OS X]] 10.6.6 and higher. FaceTime is supported on any iOS device with a forward-facing camera (namely, all iOS devices released since the release of the [[iPhone 4]]) and on any Macintosh computer equipped with a webcam, in particular those equipped with a '''FaceTime Camera''' (formerly known as an '''[[iSight]] Camera'''.)

==History==
[[File:FaceTime Logo on iOS 4.3.png|thumb|113px|FaceTime logo on supported [[IOS (Apple)|iOS]] [[IOS_version_history#4.3|4.3]] devices.]]

FaceTime was announced by Apple CEO [[Steve Jobs]] at his [[stevenote|keynote speech]] on June 7, 2010 at the [[WWDC 2010]] in conjunction with the [[iPhone 4]]. Support for the fourth-generation [[iPod Touch]], the first iPod Touch to be equipped with cameras, was announced in conjunction with this device's release on September 8, 2010.

The "FaceTime" name was purchased by Apple from FaceTime Communications, who changed their company name.<ref name="FaceTime Communications">{{cite web |url=http://facetime.com/LearnMore.aspx |accessdate=2010-06-07 |title=Our name – FaceTime |author=FaceTime Communications | quote=Apple has announced that it will use 'FaceTime' as the trademark for its new video calling application. Our agreement with Apple to transfer the FaceTime trademark to them comes as we are rebranding our company to better reflect our capabilities. We will be announcing a new name in the coming months.}}</ref>

FaceTime for Mac OS X was announced on October 20, 2010 at the "Back to the Mac" Media event on the Apple Campus.

On February 24, 2011 FaceTime left beta and was listed in the [[Mac App Store]] for [[United States dollar|$]]0.99 ([[Pound sterling|£]]0.59). Apple claims that it intended to provide the application for free, but was prohibited by the [[Sarbanes–Oxley Act]] of 2002 from providing an unadvertised new feature of an already sold product without enduring 'onerous accounting measures'.<ref>http://www.macgasm.net/2011/02/24/apple-charge-facetime/</ref> However, the free beta is still available for download from the Apple servers.<ref>http://mac.softpedia.com/get/Internet-Utilities/FaceTime.shtml - link within last sentence "The page provides access to FaceTime 0.9 Build 92 version".</ref> On March 2, 2011, FaceTime support was announced for the newly-introduced [[iPad|iPad 2]], which gained forward- and rear-facing cameras for this purpose.

== Implementation ==
[[File:IPhone call screen.png|thumb|The [[iPhone]]'s screen when a call is in progress, showing the FaceTime button (middle of bottom row).]]

FaceTime works by connecting an [[iPhone 4]], fourth Generation [[iPod touch]], a second generation [[iPad]], or a computer with [[Mac OS X]] to another similar device; the previous generations of [[iPhone]] and [[iPod Touch]] are not currently supported, however on the [[iPhone 3G]] and [[iPhone 3GS]], users can enter facetime:// urls in [[Safari (web browser)|Safari]] to trigger what appears to be a FaceTime call, although it does not truly ever successfully initiate. FaceTime is not compatible with non-Apple devices or any other video calling services. The MacBook Pro Early-2011 introduced high-definition FaceTime which may only be used with devices that have a HD FaceTime camera.

On the iPhone, FaceTime works in the Phone [[application software|application]] instead of being a separate application. It can be activated when in the Phone application by placing a call, and pressing the FaceTime button. The FaceTime button replaced the [[Hold (telephone)|Hold]] button (which is now available by pressing and holding the Mute button). The icon resembles a camcorder. It is also possible to initiate a FaceTime call directly from a contact file.

While the current FaceTime implementation for the iPhone does not officially support FaceTime calls over [[3G]] ([[UMTS]]/[[High Speed Packet Access|HSPA]]), there are 3rd party applications that enable this capability.<ref>http://modmyi.com/cydia/com.eini.facebreak</ref>

FaceTime over 3G can be achieved by using third party [[iOS jailbreaking|jailbreaking]] commercial software such as the FaceBreak, 3G Unrestrictor or My3G which fools the phone into believing that it is connected via Wi-Fi. These programs are only available on jailbroken iPhones via the Cydia Store. At the moment there are no known free of cost solutions to unrestrict FaceTime. FaceTime uses about three megabytes of data per minute of conversation, so users with a limited data plan who use FaceTime over 3G (only on [[iOS jailbreaking|jailbroken]] devices as of right now) must be careful to not overextend their data limit. However, cellular talk time/minutes aren't used after switching from a voice call to a FaceTime call.

FaceTime on iPad original is also possible by porting the FaceTime application for the iPod touch 4th gen to iPad.<ref>{{cite web|url=http://www.9to5mac.com/50959/ipad-facetime-now-possible-with-hack/ |title=iPad FaceTime now possible with hack |publisher= 9 to 5 Mac |date=2011-02-15 |author=Brian Purkiss}}</ref>

iOS 4.1 and FaceTime for Mac, iPhone 4, and iPod Touch (4th Generation) supports the use of an [[Apple ID]] email address to initiate a FaceTime call. The two parties would need two different Apple IDs to initiate a FaceTime call, although multiple IDs can reside under a single iTunes account.

== Standards ==
The FaceTime protocol is partly based on numerous open industry standards.<ref name="AppleInsider">{{cite web|url=http://www.appleinsider.com/articles/10/06/08/inside_iphone_4_facetime_video_calling.html |date=2010-06-08 |accessdate=2010-06-09 |title=Inside iPhone 4: FaceTime video calling |publisher=AppleInsider |author=Daniel Eran Dilger}}</ref>

FaceTime is based on numerous technologies:
* [[H.264]] and [[Advanced Audio Coding|AAC]] – video and audio [[codec]]s respectively
* [[Session Initiation Protocol|SIP]] – [[IETF]] signaling protocol for [[VoIP]]
* [[Session Traversal Utilities for NAT|STUN]], [[Traversal Using Relay NAT|TURN]] and [[Interactive Connectivity Establishment|ICE]] – IETF technologies for traversing [[Firewall (computing)|firewalls]] and [[Network address translation|NAT]]
* [[Real-time Transport Protocol|RTP]] and [[Secure Real-time Transport Protocol|SRTP]] – IETF standards for delivering real-time and encrypted media streams for VoIP

Upon the launch of the iPhone 4, Jobs promised that Apple would work in due course with standards bodies to make the FaceTime protocol an "open standard." As of May 2011, it is not yet known to have been ratified by any standards body, and the extent of work by Apple with regards to this promise is unclear as Apple has not released technical specifications for the service. FaceTime is not currently supported on any non-Apple devices.

While FaceTime is based on open standards, Apple's FaceTime service requires a client-side certificate.<ref>{{cite web|url=http://www.packetstan.com/2010/07/special-look-face-time-part-3-call.html | date=2010-07-09 | accessdate=2011-03-06 | title=Special Look: Face Time (part 3: Call Connection Initialization)|author=Josh Wright}}</ref> ''I.e.'' while the protocol might be open, access to Apple's FaceTime service is controlled by Apple.

==Limited availability==
As of October 2010, FaceTime is not enabled on devices bought in [[Kuwait]], [[Saudi Arabia]], [[United Arab Emirates]], [[Egypt]] or [[Jordan]], possibly due to regulations in these countries which restrict the use of IP-based communications technology. Devices bought elsewhere continue to support FaceTime even in these countries.<ref name="Register 19 October 2010">{{cite news|last=Ray|first=Bill|title=Apple wipes smile off FaceTime in the Middle East|url=http://www.theregister.co.uk/2010/10/19/facetime/|accessdate=19 October 2010|newspaper=[[The Register]]|date=19 October 2010}}</ref>

Recently however it Middle Eastern phones have FaceTime.

As of October 2010, FaceTime is not enabled on devices bought in [[Kuwait]], [[Egypt]], [[Jordan]], [[Qatar]], [[Saudi Arabia]] and the [[United Arab Emirates]], possibly due to regulations in these countries which restrict the use of IP-based communications technology.
