Who called from 3072743625

received a VM from this wireless phone number with no message.
no idea who this is calling a business line at 6:30pm on a weekend??
the dnc registry is worthless.

Got call 7am today (Saturday) silent caller.....I was pretty much annoyed...

the number called me Saturday 7/6/13 at 11am. silent.

WHO IS THIS WEIRDO? I tried to return the call and heard message  "This call is disconnected or no longer in service."  Apparently, it still is in service, as the call came at 10:45 AM!

Received call 3:10 PM ET today, and like others have said above, nothing but silence on the other end.
