Caller ID said "Maine". I didn't answer. No message was left.

someone called looking for someone they had the wrong # tired to call back voicemail said crucial instances Maine called with this Maine # idk who it is or even what they are looking for someone at this # for....

Obviously a robocaller spoofing a fake callerID.  Their robo software is set to ring only 4 times, thus avoiding hitting the answering service if you don't pick up.

I'm ignoring 80% of my calls these days.  These overseas telemarketers simply ignore the DoNotCall registry.  Phone companies are working on a resolution to end spoofed callerID calls.

Received a call with the ID saying "Maine" but we let it go to the answering machine, which says, "We can't come to the phone right now.  If you are not a telephone solicitor, charity, or political caller, please leave a message after the tone."  No message was left.

They called. Left no message.
