You know how pretty much everybody seems to have implemented spoofing controls on IP's exiting their networks? People need to get on that for the phone side (whilst yes exceptions should be allowed you really should need to prove it's your number). If it needs regulation to force it then so be it. Also, I ask them if their mother knows they are criminals trying to steal from old ladies. They get very upset by this as a rule. My 95 year old grandmother is still getting 3-5 "nbn your phone will be disconnected at midnight" calls per week.
