Ed Pinnes – APNOMS 2006 Quality Service - 7 Copyright© 2006 Telcordia Technologies, Inc. What Is VoIP Quality? How can you measure Call Quality? Subjective Testing, e.g. live listeners determine Mean Opinion Score (MOS) Sample-Based Objective Testing, e.g. perceptual-based techniques such as ITU-T P.862 (PESQ) Non-Intrusive Monitoring, e.g. statistical- based techniques such as ITU-T P.563 What Can Impact VoIP Quality? IP Network Problems: jitter, packet loss, delay Configuration and Signaling Problems: routing configuration, bandwidth allocation, capacity engineering Telephony Interface Problems: echo, signal level What is Call Quality? Listening Quality Conversational Quality Service Quality
