Added: 20-07-2021

Block unknown callers with call screening service.

By default block phone numbers that are not saved in your contacts list.


  • allow numbers that you have called

  • allow numbers with toll-free codes (ex: 800)

  • allow a third call from the same number within five minutes (cache constraint)

  • allow temporary mobile numbers from incoming text messages

  • allow numbers that passed STIR verification (android 11)

If app rejects calls from contacts on android 10, allow contacts permission manually in
app info > permissions.
