Who called from 2143066974

I have had a few calls from this number. The caller ID says local call, BUT it is NOT. I am in the Houston area~ and this area code is around Dallas. They never leave a message, NOR will I answer a call I don't recognize. I am on the do not call list~ ALOT of Good that is doing for most of us posting in here!

I have several call from this number and don't know who they are, they call and hang up.

Identified as "Local Call"--but not a local area code.  Keeps calling.
