I meant to add, that being the political animal that I am, I don't really mind the calls. And in fact, this year, all the robo calls were contained within the last two days, (which I really prefer than having them stretched over a week, as before.)
However, listening to other people this morning, I was surprised by how much they hated the calls.
If it is allowed, I can see how they would use it.
Helps a lot if calls are limited to between 9:15am stopped at 11:45am-12:45pm and then go till no later than 7pm.
My friend (a doc) gets great results with those times.
He also does not use the calling machine on weekends.
