Who called from 4340000000

I wish I had some concrete information about this number - I came here hoping to learn more :-).  They called tonight at 6 pm while I was out and did not leave a message.  Obviously the number is spoofed.  I'm guessing it might be a political call, though it's not from my state.

same here, twice today... no message... caller ID virginia

Calls from this number a few times a day, no message left.  Picked up a phone today and asked a caller to remove my name from the list.  Caller ID Virginia.

Was called back to back from this number on 5/17/20013. They didnot leave a message

Said he was calling from radio station 96.3. I advised him I was on the do not call list. He said he didn't know what the do not call list was.
