FaceTime is iChat AV for iPhone. Jobs presented an "alphabet soup" of technologies that were involved in making FaceTime work, many of which are shared with iChat AV, including:
- H.264 and AAC, its ISO/MPEG video and audio codecs (just like iChat).
- SIP (Session Initiation Protocol), the open IETF signaling protocol for VoIP used by iChat AV.
- STUN (Session Traversal Utilities for NAT), an IETF standard for dealing with lots of different kinds of NAT.
- TURN (Traversal Using Relay NAT), an IETF standard for allowing a client behind NAT to receive incoming requests like a server.
- ICE (Interactive Connectivity Establishment) an IETF standard which helps set up connections through NAT firewalls.
- RTP (Real-time Transport Protocol), an iETF standard for delivering media streams in VoIP.
- SRTP (Secure RTP) an IETF standard designed to provide encryption, message authentication and integrity for the data streams.
FaceTime uses Port 53, 80, 443, 4080, 5223, and 16393-16472 (UDP).
