Call screening – How to check Robocalls by pressing a specific key combination? (Audio CAPTCHA)


I try to stop all the junk calls I get. I've tried some apps like Hiya, TrueCaller, and so on. Unfortunately, phone numbers are easy to fake and these apps can not display all of these spam emails

Allowing calls only from my contact list is not an option for now

question – Is there a way to answer the call Ask caller to press certain keys (Playback message such as "Press 4-5-6 to connect") and disconnect the call if the caller did not (Audio-CAPTCHA)

I have Android 7.1.1
