If you use a VoIP service like Twilio and voip.ms, you can set up a very simple IVR menu that just asks unknown callers to press 1 to be connected to you. No AI involved.

For me, this has been surprisingly effective against robocalls. Obviously this isn’t going to work against scammers who call directly, but most of the spam calls I receive start with some pre-recorded message which isn’t going to pass the menu.

Edit: s/auto/pre

It's a great idea, and in Canada using the Koodo/Telus network you can turn on "call control" for free which does basically this, except it makes the caller enter a random number between 1-9. And you can also whitelist certain numbers like friends and family.
