VOIP ROUTING BASED ON RTP SERVER-TO-SERVER ROUTING

摘要

A system and method of providing VoIP services by using multiple Real-time Transport Protocol servers (RTP) servers for transmitting VoIP data between user endpoints. The RTP servers are selected based on the network addresses of the respective endpoints according to the network topology. Traffic mirroring is established among the selected RTP servers. Each RTP server is responsible for transmitting the VoIP data representing the video/audio signals received at its associated endpoint to another RTP server which then relays the VoIP data to another endpoint. Further, routing optimization can be performed to select a network route between the selected RTP servers for RTP data transmission.
