| Abstract(in English) | In this paper, we evaluated a VoIP system and examined PSQM+ while changing the voice data length of IP packets on various packet loss and transmission jitter conditions in a real network. We proposed a new VoIP system that changed VoIP parameters like the voice data length in IP packets according to the dynamically changing network QoS conditions using evaluation results. This system achieves both high transmission efficiency and voice quality stability. |
