Unlike videophone calls, videoconferencing is designed to serve a conference rather than individuals. Videoconferencing captures the realtime, interactive components of communication through voice, eye contact and facial expressions. Recent technological advances allow for real-time transmission of documents and medical data, aural and visual. Currently, videoconferencing systems run over ISDN, private and public Internet. New video and audio compression techniques allow for higher quality and use less bandwidth. New Desktop solutions allow users to connect to conferences from their office desk or home computer. With integrated audio solutions, users can connect to conferences with their cell phones, albeit audio only
