  • Abstract
    This paper deals with analysis of relation between IP channel characteristics and final voice transmission quality. For adjusting of IP channel network emulator NISTNet is used. Criterion of transmission quality is a MOS parameter investigated with an algorithms ITU-T P.862 PESQ, future P.863 POLQA and P.563 3SQM. The following characteristics have been explored: codec PCM, codec Speex, jitter and packet loss.
