That's essentially the law in America too. For the last 20 years or so, we've had the "Do Not Call List" and if you add your number to it, you don't get these calls. Unfortunately that law only works for land lines. Cell phone spam was virtually unknown 20 years ago because cellular minutes were not free, and anybody who wasted your time on a cell call could be sued for costing you money. Also back in those days there were no comprehensive databases mapping people to mobile numbers. Finally there didn't exist easy ways of spoofing your caller ID number so if you spammed someone you would likely be caught. That's all different now, which is why the old law needs to be updated for mobile phones.
