Who called from 3122609810

Picked up.  Heard click.  Nothing else.

No one was there!!!

Called after 8 pm, I heard a click and they hung up.

Maybe a robo-call?  Nobody was on the line.

They called, but didn't leave a message and I didn't pick up cause it's my landline and I am on the DNC Registry.  Sounds like if I picked up, no one would be there anyway according to the other people that have left a post about this number.

I'm just blocking it right now to avoid further calls. :)
