I just got a call from this number at 6a.m. pst on my cell phone. Don't know this person. Message mumbled asking me to call back. Woman's voice.
I called back and got a male. He states that his company is a moving company. Would  not provide his address. This call was from Dallas TX.  
Lat 33
Long 397
Zip 75201 LAN Line.
Wanted my phone number ....which I didn't provide.
I am not sure if this was a prank or a way toverify  gather cell phone numbers.
I live on the West coast

I just got several calls right in a roll from all kinds of Dallas numbers and a call from St. Louis.  I am on a do not call list.  They never leave a message.
