SMB VoIP Fraud Watchdog
A monitoring service for small businesses using VoIP phone systems that detects toll fraud, IRSF (international revenue share fraud), and robocall-style abuse in real time and auto-blocks suspicious outbound routing.
Small business owners and IT leads using cloud VoIP for customer lines
- Real-time anomaly detection on outbound calls (sudden spikes, international destinations, off-hours volume)
- Auto-throttle or block suspicious trunks with one-click override for legitimate activity
- Per-extension risk scoring and weekly fraud exposure report
- Carrier integration layer with recommended dial-plan rules to harden the PBX
