AFAIK in Germany doing a Robocall is illegal if you didn't get clear consent from the called party first (300'000€ per call, additional 10'000€ if the number was hidden). The german telcos have to my knowledge also started to block large lists of numbers used by the scammers if they are incoming calls. Some stuff still works like callback scams (They ring you for a few seconds, then hang up, calling back is expensive). There is also the difference that the US is 300 million people that basically all speak english, which is a cheap option to hire for in Indian callcenters. Europe is much more diverse and the languages are more expensive to hire for, so it's less profitable.
