How does CallerAPI prevent telecom fraud?

Three layers that work together: a spam database feed you host at your switch (refreshed every minute), a real-time Caller ID API that returns a spam score and complaint history per call, and a SIP firewall that drops fraud traffic at the network edge.

Can we block spam calls at the switch level?

Yes. The Spam Database Feed is built for switch and SBC-level blocking: you host the blacklist yourself, it updates every 60 seconds, carries 15 days of rolling history, and adds zero lookup latency to call setup.

Which countries does the fraud detection cover?

Fraud and spam call detection covers 30 countries and keeps expanding. Business phone number identification covers 195 countries, so legitimate callers can be verified instead of blocked.

Can we resell spam protection to our subscribers?

Yes. MVNOs and carriers license white-label call blocking SDKs for Swift, Java/Kotlin, Flutter and React Native, plus an Asterisk module, and sell protection under their own brand. Licensing is a flat fee or per subscriber per month with active call blocking.

Telecom fraud prevention for carriers, MVNOs and CPaaS

Stop robocall and fraud campaigns before they reach subscribers: a minute-fresh spam blacklist, a spam call blocking API and a SIP firewall, working as one stack.
