Blocking is still the first line of defense

Use your phone, carrier, and a reputable filtering app to stop as much unwanted traffic as practical. Stall the Scam is for the smaller set of suspicious live calls that still ring through.

It runs beside the call, not inside your phone line

Open Stall the Scam in Chrome on a laptop or spare phone. Put the suspicious incoming call on speaker and press Start. The second device listens for the caller and plays harmless delaying responses.

It does not need a forwarding number

There is no phone-number porting, forwarding configuration, dialer replacement, or telephony charge. The customer remains in control of the original incoming call.

It gives the caller nothing useful

The response library uses misplaced glasses, slow software updates, repeated questions, and harmless confusion. It never supplies real personal, account, payment, or authentication information.
