VoIPmonitor provides comprehensive call quality monitoring based on industry-standard metrics. Our system passively monitors your VoIP traffic and calculates real-time quality scores for every call.
Interactive 2D and 3D reports for MOS, packet loss, jitter, and PDV metrics with drill-down capabilities.
Key Metrics We Monitor
- MOS (Mean Opinion Score) - ITU-T G.107 E-model calculation predicting voice quality on 1-5 scale
- Jitter - Variation in packet arrival times affecting audio smoothness
- Packet Loss - Percentage of lost packets impacting call clarity
- PDV (Packet Delay Variation) - Network latency fluctuations
- R-Factor - Transmission rating factor for network quality assessment
Real-Time RTP Stream Analysis
Monitor the quality of each RTP stream in real-time. Visualize jitter, packet loss, and MOS score progression throughout the call duration.
RTCP Statistics
Leverage RTCP (Real-time Transport Control Protocol) data for accurate jitter and packet loss measurements reported directly by endpoints.
Packet-Level Deep Inspection
Drill down to individual RTP packets with Wireshark-like detail view. Analyze exact timing, sequence numbers, and identify specific packets causing quality degradation.
One-Way Audio Detection
Automatically detect and visualize one-way audio issues with comparative 2D and 3D graphs showing audio flow asymmetries.
Long-Term Quality Trends
Track quality metrics over time with trend analysis. Monitor ACD (Average Call Duration), ASR (Answer Seizure Ratio), NER (Network Effectiveness Ratio), and SEER for comprehensive service quality assessment.
