Since I and most everybody I know will never answer a call from a number not in their address book as a direct result of robocalls, I'm not sure that this is a huge issue.

If, for instance, my water company called me with such a notice, it's not likely I would actually hear about it that way, because I'd assume it was a robocall. I'd more likely hear about it through other media outlets.

No one you know has kids? People with kids have to take calls, in case it's a facility with something to report, so they can't ignore any calls.

I know several people with kids, and I have kids of my own. They're no longer young enough for this to matter, but even when they were, I still ignored calls. The main difference was that I actually bothered to listen to any voice mails unknown callers left.

There are people that can only be reached with a phone call. The water company has a responsibility to at least try to reach them.
