Hello, I've choosen only MOS-LQE because it is calculated only on network parameters, which is loss, burstinnes and delay (which is converted to loss by jitterbuffer simulator). It does not takes into account voice (payload). There is no effective objective methods (today) which predicts MOS. Only ITU-T P.862 and P.563 which is patented and it can analyze only 20 seconds samples. I've tried implementing P.563 and it is not usable for real live use, only for automated tests which is not in my interest now (and because of patents). I've calibrated MOS-LQE with polynomial functions using P.862 PESQ. I will write more on voipmonitor.org documentation once I've found more time.
I'm using voipmonitor on central gateway and succesfully monitoring all SIP traffic and filtering calls by the worst MOS. So yes, you can use that tool for measuring quality of IP network in realtime. If you save PCAP files, you can analyze it with wireshark in more depth.
