Method and device to monitor the transmission quality of a voice signal over an IP network

摘要

Method for testing the transmission quality of a bidirectional real speech transmission or multicast connection over an IP network (11) between a first VoIP endpoint (13a) and a second VoIP endpoint (13b), wherein over a predetermined, sufficiently long time period, a first number of transmitted from the first to the second VoIP endpoint RTP voice packets and a second number of transferred from the second to the first VoIP endpoint RTP voice packets is detected and the first and second number of arithmetic processing are subjected to obtain a transmission quality value representing the result of which becomes.
