Is there a captcha-like call blocker?

    I use Callcentric VOIP for my landline. They have a fantastic feature that has eliminated marketing robocalls. It works like this: unless the caller is in my contacts, the call is answered by Callcentric's own robot, which asks the caller to press a digit to be connected. Real human callers press the number, but robocallers assume it's voicemail and hang up. The vast majority of telemarketers use robocallers, so this has been extremely effective in getting rid of spam calls.

    Is there an Android app with this functionality? All the call blockers I can find are just some variant of whitelists and blacklists. That just isn't good enough!

    I think that what you want, is going to have to be provided by your carrier.

    I just don't see how an app on the phone can prevent an incoming call from ringing your phone, and asking the caller to input a digit to put them thru to you.

    I looked at a lot of call blocking apps, and they all seem to be "carbon copies" of each other.

    have you looked into using Google's service? get a Google number and set that up, and if they are a 'real human' it can then call your phone?

    Thanks. I looked into Google Voice and it works by asking callers to state their name, and then forwarding the call. The recipient is then able to decide whether to accept the call based on the name. The problem is that robocallers start talking as soon as the call is connected, and their jabbering could be taken by Google as the name. So rather than Google hanging up on them, I would still be bothered with the call.

    Of course, Google might be smart enough to figure out whether a spoken "name" is likely to be a real name or a robot's introductory come-on. So, I wonder what people's real-world experiences are. If you use Google Voice, do you still get robocalls?

    Truecaller is not preventing the phone from ringing if the caller is not in his list of contacts.
    I read thru the Remarks and it has the same problems that all the other call blocking apps do.

    if the phone rings, I have to look at it to decide if I need to answer it.

    Blocking 'non contacts' is a no no, as a full 3rd of my calls come from doctors, hospitals, clinics, etc... and there is not way to have their numbers in advance, and most of them are behind a switchboard and don't give you their real number.

    it seems their last update screwed the pooch, they have merge a dialer into it... that is a real mistake.

    I agree with your posts on this subject, 100%. AT&T has a handset for the landline with this feature. I also wish to find an Android app that does this. Have you or anyone found one yet?
