In the UK we have the Telephone Preference Service (TPS) http://www.tpsonline.org.uk/tps/index.html
This is a free service where you can register your phone number. All (legitimate and professional) telemarketing companies operating in the UK must use the database to remove numbers from their cold-calling database or face action from the Information Communications Office (ICO). The Direct Marketing organisations pay for this service themselves.
It doesn't stop international scammers from "Windows Technical Support" calling - or illegitimate cold-calling organisations, but it helps thin the herd and properly identify when someone should be phoning and when they shouldn't.
The Premium number organisation does not recommend consumers setting up a premium rate number and using that when registering for web-sites because it is hard for individuals to ensure that they comply with premium rate regulations, which could leave them open to claims from companies. Just saying.
