At least most of the Spanish one can be banned by blocklisting a whole company. which is what I did following a guide I found, and have reduced my Spam calls from 2 per day, to 3 per year.

However, the only way to solve this I believe is that you could once you get an unsolicited call to press a combination like ##01, and automatically this is passed to an agency that deals to punish whoever is behind the call in real time. At least if they call from a national number.
