Called my cellphone at 4:08p.m. on 04/28/13. My wife answered as I was unavailable. They asked for me by name and former employment location. I returned the call two minutes later and got a half of ring before it went to busy. Tried twice and got the same thing.

This number called me at 11:11 pm on a Wednesday night.  I tried to call it back and it rings half a ring and then there is a busy tone.
