A plumber I use has gone back to the old days and has an answering service. If the call is legit they let him know right away and he calls back in minutes. They only forward real service calls, the rest that actually pass wait for his attention when he's not working a job. And the junk calls he doesn't even know about. IDK about random number dialing, they must get to him now and then but he never picks up unless they have called the number at the service. I bet he has his sound off with only the service as a 'favorite' which will ring.
