The document describes a service that monitors VoIP traffic from multiple suppliers. It uses RTP proxies and Voipmonitor to analyze 90% of VoIP traffic and Sevana analysis for the remaining 10%. The service analyzes audio quality issues like amplitude clipping, VAD clipping, stuck clicking, SNR, echo, and plans to add DTMF and FAX analysis. It evaluates quality over multiple time windows, calculates average quality impact per window and most influencing impairments. The service also statistically predicts MOS scores and uses various algorithms to evaluate overall supplier quality, allowing flexible parameter tuning.
