Technology
Layered detection, explainable decisions.
VoIP Radar combines certainty where it exists with machine learning where it's needed — and records why every decision was made.
Detection layers
Each layer removes risk for the next
Numbering hygiene
Invalid, unallocated and Do Not Originate numbers are blocked deterministically, with near-zero false positives.
Call authentication
STIR/SHAKEN signatures are verified and attestation levels evaluated against what the customer is entitled to present.
Customer context
KYC status, expected traffic profile and number inventory define what "normal" looks like for each customer.
Reputation
Number, range and source reputation from network-wide outcomes, complaints and fraud intelligence.
Behavioral ML
Models score calls-per-second, duration, answer rates, fan-out, destination mix and timing against baselines.
Policy & audit
Your thresholds decide the action; every decision is logged with its inputs and reason codes.
Why explainability matters
A risk score on its own is not evidence. Regulators, traceback investigators and your own customers want to know why a call was blocked or allowed. VoIP Radar stores the features and rules behind each decision, so you can explain any call after the fact — and tune policies with confidence.
Audit records are written to an append-only, tamper-evident log, giving you a reliable history for RMD documentation, traceback responses and disputes.
