called, machine answered, they left no message.

Looks like another scammer to me - i no longer pickup my phone unless I recognize the caller, so cannot ID

No message left. Caller now blocked.

Caught a male voice with my shrewd pause. He quickly switched it to an automated voice telemarketing message -- something about Police Association, which is a scam pseudo charity to get you to donate money.

Yes just received this message stated hello 4 times don;t leave a message or anything so I chop it up as scammers, telemarketers, all of the above.  I don't answer my phone NO more, I guess doesn't matter rather your home phone is not listed, they somehow get a hold of it.  So just let my answering machine answer it, and if it was important, then I guess they will leave a message with a name, person or someone who isn't harassing you.
