Always blocks the first call from unknown numbers - perfect for spam and scams.
Say goodbye to spam and nuisance calls without missing important ones!
InsistCall is a call blocker designed to protect you from unwanted calls quickly, easily, and automatically.
It works very simply: the first call from an unknown number can be blocked. If that same person calls again within your set timeframe, InsistCall recognizes the second call and allows your phone to ring normally.
This way, you can reduce interruptions without completely shutting the door on a truly important call.
HOW DOES IT WORK?
• First call from an unknown number: InsistCall can intercept and automatically block it.
• Second call: If the same number calls again within the configured interval, the call can be allowed through.
• Configurable timing: Set the time window for recognizing a second call according to your preferences.
• Automatic operation: Once set up, the filter runs in the background using Android's official call-filtering functions.
