Who called from 3012346207

Upon answering the call, the caller hung up without saying anything.

Weird.  I let the answering machine pick it up because I didn't recognize the number.  Someone actually was on the line, said hello a couple of times and then hung up.  I didn't pick up the phone because I didn't recognize the voice.

We have gotten a call from the number as well.  We let the machine pick up.  The person says, "Hello" and that is it.  caller ID said Clinton, MD.  Sort of spooky.

Same thing calling me, Hello, Hello. I called the number back from a blocked phone number and a recording the number you called is not in service.

This # calls all the time hangs up when answered always calls around 8pm or later needs to stop
