PURPOSE: A method for measuring the QoS of a VoIP network is provided to measure the quality of a VoIP network through a fixed algorithm. CONSTITUTION: A VoIP network quality measuring server checks the sequence number and time stamp of RTP packets(S205). The VoIP network quality measuring server measures VoIP network quality in an upstream connection(S206). The VoIP network quality measuring server measures the entire loopback VoIP network quality based on the sequence number and time stamp recorded in payload regions of the RTP packets. The VoIP network quality measuring server extracts the correlation between the measured entire loopback VoIP network quality and the VoIP network quality. The VoIP network quality measuring server measures VoIP network quality in a downstream connection.
