VOIP COMMUNICATION SERVER BASED ON SIP, VOIP COMMUNICATION NETWORK AND VOIP COMMUNICATION METHOD

摘要

PURPOSE: A VoIP communication server based on a call setup protocol, a communication network including the same and a communication method thereof are provided to convert data properties or network properties into a format that another network can understand and process, thereby identically controlling properties of two networks. CONSTITUTION: During VoIP(Voice over Internet Protocol) communication using an SIP(Session Initiation Protocol) and an RTP(Real Time Protocol), a VoIP communication server based on SIP receives data from a network in one side. The VoIP communication server transmits the received data to another side network. The VoIP communication server converts the data into a format which can be understood and processed in another side network.
