How it works
From SIP INVITE to verdict in milliseconds.
A six-stage pipeline turns raw signaling into a real-time decision — and a permanent audit trail — before the call ever connects.
- 01
Capture
VoIP Radar receives call signaling and metadata from your SBC, softswitch or trunk: calling and called numbers, Identity header, customer and trunk, routing, timing and destination.
- 02
Enrich
Each call is joined with context — the customer's KYC record and number inventory, numbering data (validity, allocation, portability), and network-wide reputation.
- 03
Screen
Deterministic layers run first: Do Not Originate, invalid and unallocated numbers, STIR/SHAKEN verification and customer-specific rules.
- 04
Score
A machine-learning model compares the call with the customer's historical baseline and known fraud patterns — CPS, duration, destinations, fan-out and more — to produce a risk score.
- 05
Act
Your policy turns the score into action: sign with the right attestation, tag, rate-limit, or reject with SIP 603/608 — and alert your NOC when it matters.
- 06
Record
Every decision is written to a tamper-evident audit log with its inputs and reasons, ready for traceback, disputes, RMD updates and regulators.
Deployment
Fits around your existing network
Most providers integrate VoIP Radar with a single routing change: the SBC or softswitch consults VoIP Radar (via SIP redirect or API) and acts on the response. Only signaling is inspected — media stays on your network — and legitimate calls proceed without noticeable delay.
Dashboards, alerting and exports sit on top, so your NOC, fraud and compliance teams all work from the same evidence.
