Abstract :
This paper deals with analysis of relation between packet delay variations (jitter), length of jitter buffer and final voice transmission quality. For adjusting of IP channel network emulator NISTNet is used. For adjusting of buffer length VoIP client Linphone is used. Criterion of transmission quality is a MOS parameter investigated with an algorithms ITU-T P.862 PESQ and P.863 POLQA.
