20 spam calls per day? That sounds like torture... is there really no body in USA that would prevent that from happening?
(I've never received a spam call on my now 20 year old phone number.)

Here's what does work (in my experience): answer the call, but say nothing, heck, mute your phone mic if you have to. Just give them silence. I'm not sure if there's some 'person on the other end' detection algorithm or what, but I went from 10-15 spam calls a day to 1 every few days. It took a little while, but it worked. Just don't answer strange numbers with a 'hello?', if someone's trying to reach you, they'll usually say it first.
I don't get that many spam calls, but what I do when I get one varies from answering and immediately hanging up to doing what you suggested (which usually results in them disconnecting after about 5 seconds). Occasionally, I've done things like answering the call and snapping my fingers in the receiver instead of saying "hello" and that usually results in an immediate disconnect.
I'm not sure if any of those things have affected the volume of spam calls I receive though.
Anybody legitimate that's not true. But it's so easy to spoof your number that there are a lot of bad actors.
That being said, I also try to be pretty careful about putting my phone number out there, taking time to judge when a real phone number is needed or not, and asking pretty specifically for what reason a company wants my phone number and often just ignoring the service if an adequate reason isn't given.
Since I've moved abroad, I have apparently been less careful and I occasionally get calls and texts on my foreign sim, and I must have given my email out as there are suddenly lots of hot-singles looking for me, but it is 100% related to my current region, whereas before my Spam folder sat untouched.
Consider yourself lucky to never gets calls of this type. Between the out and out scammers and pollsters/political calls/charities (the latter categories are protected from landline junk call bans), I routinely get 3 or 4 a day.
In practice... there's some groups who are still allowed to call you even if you're on the registry. Others will just ignore it, and filing a complaint is difficult.
Not give them a big tiresome speech about how they are breaking the law, just ask them not to call anymore ("Please put this number on your courtesy do not call list"). They actually don't want to waste their time...
A lot of the calls I used to get were the ones where they spoof a phone number that has the same first few digits as yours to make it seem like a local number and then the caller is a scammer “You owe money to the IRS”, “Your computer has a virus and you have to pay to fix it”.
Engaging these callers is probably not useful.
Unfortunately, it still won’t prevent my number from being spammed. There is no human to talk to. Any indication you are alive is a confirmation your phone number is worth calling. The only thing you can do to convince them is not answer or somehow communicate a likely disconnection from a human.
The internet myth is that this marks you as someone to keep calling (because you listened), but really they will stop.
I mean, I get ~1 unwanted call a week across a couple of phone numbers (that I answer and ask to stop). Other people are saying that they get a dozen a day and giving up on their phones. My anecdotes work for me.
