This number from "Hayden AZ" called and hung up when it didn't get my message machine, which I have turned off and that action has reduced most of the scam calls.  I have a Call Blocker also but was not close enough to block them, will have to wait until next time, if there is a next time.  Usually, the robo caller picks up the fact there isn't an answer machine and rolls past me.

520-200-1289, caller ID showed Hayden, AZ. he left a message on the machine..."This is John & I'm calling with the American Police & Sheriffs Association"  I doubt that & if he calls again, he still wont get an answer. Must be a new kind of scam

I just liked up the American Police & Sheriffs Association. They are on the Charity Watch & have very bad rating...sorry I didn't look it up before my other post

Called Sunday morning.
I don't answer calls from numbers I do not recognize.
Another call from Tucson prefix came in Sunday evening.
Both are apparently posing as a charity collecting for American Police Association

Call from Winkelman, AZ.  I picked up after the second ring and they hung up.
