I don't understand why this is so hard to correct.
1. How many calls do you make a day?
2. How many do you think a robo caller makes a day?
3. How many legit companies need to make as many calls as #2?
4. Why can't the phone providers just monitor use, and limit the number of daily calls, with out a vetting process?
Seems simple to me.
Am I correct most people get robo calls come from their own area code?
I'm changing my next phone's area code to 406 (Montana), if you live in Montana, I will not answer your phone, sorry.
