This document discusses video chat capabilities on Apple and Android devices. It summarizes Apple FaceTime, describing how it works on iPhone 4 using SIP and proprietary protocols over WiFi. It notes FaceTime's advantages of being integrated into the phone but also its disadvantages of only working between iPhones on WiFi. It then discusses challenges for video chat on Android, which lacks integrated capabilities due to its open nature. It proposes a solution using RADVISION's BEEHD technology to bridge Android's framework and capabilities with applications and media management for real-time video calling.
