I feel this could be solved by crowdsourcing, assuming the support from the major phone manufacturers and possibly governments. - After a call from an unknown number concludes, the phone could offer an option to the user to mark it as "spam" (blocking the number in the history would have the same effect). - The spam mark would then go into the central database. If a phone number was marked as "spam" too many times, it would no longer be able to ring the phone (maybe it gets diverted into the "spam folder", like e-mails). Or am I being too naive here? What are the obstacles for something like this actually happening?

That would work well assuming scammers and stuff are actually blocked from spoofing phone numbers

My google android phone already does this. I get basically no spam calls at all except very rarely. But I go to the spam tab in the phone app and I see there are dozens that got blocked

You cannot trust which number which is signalled to the end user. Most spam calls I get is shown as legit numbers. If I call them back they will go to an innocent and unsuspecting user. Google is already collecting this information and shows numbers as "probably spam". It is hard to enforce this harder even with collateral damage as you cannot trust the number which is signalled. Legislation is in this case a good thing which might get the telcos to take this more seriously. This needs to be handled on an operator level. Nothing will happen without legislative incentives. The world is run on SS7 which has a lot of problems which inertia and lacking incentives makes hard to overcome. https://en.wikipedia.org/wiki/Signalling_System_No._7 https://en.wikipedia.org/wiki/Signalling_System_No._7

  The Orange Telefon app? So far it's good but I had some reverse situation where my outgoing call to bank call center was marked as "unwanted". I wonder why Orange so far doesn't support built-in iOS SMS/Call Reporting feature with that app
