Method to allow voice, video and data conference with minimum bandwidth consumption between two or more geological locations and achieve quality of service (QoS) and scalability

摘要

A system and method to allow voice, video and data conference with minimum bandwidth consumption with endpoints in two or more geological locations. The system includes signal server to manage one or multiple media servers. The method supports transmission of only one data stream between two media servers while each media server can support multiple endpoints. The method can achieve voice/video/data quality of service (QoS) and scalability. The servers and endpoints send/receive commands and data using TCP, UDP or any proprietary protocol, depending on server's configuration and protocol requirements. This method is compatible with existing communication standards, such as H.323, SIP, MGCP, MEGACO, and T.120.
