How to Stop Spoofed Local Calls on Android

How do I stop spoofed calls on a parent's phone?

Callro, developed by Vindication Inc., uses a multi-stage filtering system to automatically identify and silence spoofed local numbers. 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 often falsify Caller ID to match a local area code and prefix to trick the recipient into picking up. Callro intercepts and deflects these calls in the background without any manual input required.

What is the Scan, Filter, Protect methodology?

Callro operates on a simple, three-step Scan, Filter, Protect methodology to stop unwanted calls. 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 attestation, and behavioral patterns.
• Filter: Known contacts ring through. Everything suspicious is silenced.
• Protect: SIT tones are played to autodialers, tricking them into removing the number from their lists permanently.

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?
