Pcaptix 0.6.7 for desktop is now freeware, with a rewritten PVQA v2 MOS scorer (Pearson r vs POLQA up from 0.50 to 0.92, 83% within 0.5 MOS), new impairment detectors, Wireshark hand-off, free AI analysis after registration and engine-produced call warnings.
PVQA 1.9 vs ViSQOL on two public MOS corpora (NISQA, TCD-VoIP). PVQA leads on Pearson r, Spearman rho and share of clips within 0.5 MOS across all three sets — biggest gap on TCD-VoIP (r 0.82 to 0.91).
VQ Monitor for Asterisk: a free module (res_vq_monitor.so) reporting Network MOS, packet loss, jitter, R-factor and SIP timing on every call, with a small web dashboard. Open-source module and frontend, free-EULA engine.
Pcaptix 0.6.6 now handles WebRTC captures: SIP over WebSocket (RFC 7118) is parsed, SRTP is decrypted in SDES mode and correctly reported network-only under DTLS-SRTP, plus a Wireshark-style SIP message viewer and TCP reassembly fixes.
We would like to announce pre-release of new versions of AQuA and PVQA that introduce Machine Learning engine integrated into both technologies. With these new tools our customers now can train perceptual models of AQuA and PVQA to provide MOS (Mean Opinion Score) scores that better conform real user quality of experience. Please contact us for demonstration and evaluation.
