How to Stop Spoofed Local Calls on Android
How do I stop spoofed calls on a parent's phone?
Callro uses a multi-stage filtering system to catch and silence spoofed local numbers before they ring. When a suspected spoof is detected, Callro silently auto-answers and plays an SIT (Special Information Tone) to trick the autodialer into hanging up — the phone never rings.
Scammers spoof Caller ID to match local area codes so the recipient picks up. Callro intercepts and deflects these calls in the background without any manual input required.
What is the Scan, Filter, Protect methodology?
Callro stops unwanted calls by scanning, filtering, and protecting in real-time. This happens instantly on the phone, preventing the screen from lighting up or ringing when a scam call arrives:
- Scan: Every incoming call is instantly checked against known spam databases, [STIR/SHAKEN](/blog/neighbor-spoofing-stir-shaken-explained) attestation, and behavioral patterns.
- Filter: Known contacts ring through. Everything suspicious is silenced.
- Protect: Callro rejects the call before it reaches your phone, using Intelligent Network Rejection (INRS) — no audio tone is generated or played.
Does this require manual contact list management?
No. Callro never requires manual contact management. The application runs constantly in the background, separating the safe calls from the malicious ones automatically.
Is the address book safe?
Yes. Callro processes all call data directly on the device and never sells personal information. Address books, phone numbers, and call logs never leave the phone.
How much does Callro cost?
