TrueBlocker is a call blocker, with that you can determine which callers reach you. So it is possible with activated TrueBlocker, that for example only the group "family" can reach you.
All others only hear a busy signal. Of course, your phone will not ring if the caller is not a member of an allowed group to call you.
By working with groups there are only a few clicks to block or allow hundreds of callers by True Call Blocker.
How it works
1. Open the app
2. Toggle ON/OFF to start & stop the application
3. Pick the contact from phonebook or add manually
4. Get the call from whitelist group only
