Who called from 2402074493

Called number back. "This # is no longer in service" after it rang 10+ times.

I'm on the DNC list. Shouldn't be getting calls.
Tried calling it back. Number "not in service."

Woman asked for my husband by first name - said he wasn't home and who is calling and she promptly hung up.  Caller ID is Damascus, MD.  Called number back - recording saying this number no longer in service.  We are also on the DNC list.
