VoIP / SIP Monitoring That Catches Outages Before Customers Call
Most uptime monitors only check HTTP. They miss SIP trunk failures, registration loss, and PBX outages — the things that actually break a phone system. StatusCore monitors SIP natively, from three regions, around the clock.
Why generic uptime tools miss VoIP problems
Pingdom, UptimeRobot, and the major uptime players check whether a web server returns HTTP 200. That tells you nothing about whether your PBX is registered, whether your SIP trunk is up, or whether calls actually connect. A "100% green" status page next to a phone system that hasn't taken a call in 6 hours is a familiar (and embarrassing) story.
StatusCore performs actual SIP registration attempts — same protocol your phones use — from multiple regions, every check interval. If your trunk drops or your PBX stops responding, you know within seconds.
What StatusCore monitors for VoIP
📞 SIP Registration
Sends a real REGISTER request to your PBX or hosted SIP service. Confirms 200 OK. Works over UDP, TCP, and TLS.
🌐 SIP Trunk Health
Multi-region checks (US-East, US-West, EU) catch carrier-side issues that a single-location probe would miss.
⏱️ Response Time Tracking
Measures registration latency over time so you can spot degrading carrier performance before it becomes an outage.
🔔 Alert on Failure
Email, SMS, Slack, Telegram, Discord. Customizable sensitivity (alert on any region failing, majority failing, or all failing).
🛡️ Auth-Aware
Authenticates with your real SIP credentials. No throwaway probes that get blocked by your provider's rate limits.
📈 30-Day Uptime History
SLA-grade reporting. Per-region uptime percentages. Incident timeline with acknowledgement workflow.
Who this is for
- VoIP-focused MSPs managing multiple customer PBXs (FreePBX, 3CX, FusionPBX, hosted Yealink/Grandstream)
- Hosted PBX providers needing customer-facing status data
- Mid-size businesses running their own on-prem or cloud PBX who want third-party verification of uptime
- Call centers where 30 seconds of trunk loss = lost revenue
