Who called from 3016658000

I got a call from this number telling me it was a meeting of a Republican club in a neighboring town.  It was a recorded message.  I tried calling back and was told it was a non-working number.
I don't know why they called or how they got my number; I don't think it was a true political call.
Anyone else get this????

Heard some talking muffled in background, maybe a phone bank. Nothing said, nothing clear, and disconnected after about 7 seconds.

I got a call from this number, tried to re-dial and was also told it was a non-working number.  When I tried to use ATT call-blocking, that didn't work either.

tried to return call and was advised it was a non working number

The message identified the caller as Normarene Merritt.  I am assuming this is someone calling for politicians asking for vote
