Video conferencing, or video teleconferencing, is the use of telecommunications technologies to allow two or more locations to communicate simultaneously using audio and video transmissions. Video conferencing solutions have been available for the last few decades, but only recently have used the power of IP and SIP to transmit video in high definition. With the most current video solutions, users can place video calls from their PCs or desktop devices with the same ease of placing a telephone call.
Video solutions can have a tremendous impact on business. They can enable real-time, face-to-face communications without having to leave the desk. This can translate into a large cost-savings from reduced travel expenditures, and reduced travel time for employees. Moreover, video conferencing solutions are ideal in situations where non-verbal information is an important part of the conversation.
Today, there are three major protocols at work in the video world: ISDN, H.323, and SIP. ISDN-based video networks have been around since the 1980s, and refers to a lower bandwidth capability. H.323 (IP) and SIP based video systems are more current, and provide for higher quality images including 720p high definition or higher. An application like Avaya Aura® Session Manager can serve as an integration point between legacy ISDN, H.323 IP, and SIP based video conferencing systems.
