VoIP Call Troubleshooting
in Under 15 Minutes
SIP VAULT captures SIP signaling, RTCP quality metrics, and OpenSIPS logs in real-time. Identify UAC vs UAS issues, detect one-way audio, and get AI-powered root cause analysis.
Dual Capture Mode
eBPF for modern kernels, libpcap for legacy systems. One agent binary, auto-detects at startup. Supports CentOS 6 through Ubuntu 24.
UAC / UAS Analysis
Per-direction MOS, jitter, loss, and latency. Instantly see if the problem is on the caller or callee side with OWA/NOA detection.
Codec-Aware MOS
ITU-T G.107 E-model with codec-specific impairment factors. Supports G.711, G.729, G.722, GSM, Opus, and more.
Real-Time Charts
MOS, jitter, and packet loss time-series with threshold zones. See quality degradation events at a glance.
AI Analysis
Ask questions about call quality. The AI agent analyzes RTCP metrics, SIP signaling, and logs to identify root causes.
Multi-Tenant
One server, many customers. Per-customer R2 buckets with HMAC-signed dashboard access. No shared data, no database.
