Operational SIP Monitoring

External SIP visibility for VoIP providers

Detect intermittent SIP timeout, RTT spikes, and signaling degradation before your customers notice them.

Lightweight external SIP probing from Frankfurt. No agent. No integration required.

Internal monitoring is not customer experience

What your NOC sees internally is not always what your customers experience externally.

Internal View

  • SBC reachable
  • SIP service up
  • Nagios green
  • CPU healthy

Customer View

  • intermittent timeout
  • slow call setup
  • RTT spikes
  • inconsistent signaling

Why This Matters

A 1% signaling degradation on a platform handling 100k calls/day can translate into ~1,000 failed call attempts.

Real external SIP health report

Generated from low-rate SIP OPTIONS probing over multiple days.

What is monitored

Success rate

SIP OPTIONS response success over time windows.

Timeout rate

Intermittent timeout frequency and clustering periods.

RTT drift

Baseline round-trip drift to detect gradual signaling latency changes.

SIP response consistency

Status code and header consistency across probes.

Latency spikes

Short-term jitter-like spikes that impact setup responsiveness.

Multi-location probing

Cross-check behavior from distributed external vantage points.

Free 30-day external SIP health check

Low-frequency external SIP probing from Frankfurt focused on signaling reachability and degradation detection.
