I've received several calls from this number today.  They never leave a message.  I'm assuming it is solicitation.

I received a call from this number - When I answered , there was a long pause before a lady spoke and asked for my Mother. When I told her that my Mom was deceased, the lady asked for me to send a Death certificate to them, but would not tel me why they needed it nor what the call was about. I asked what company was calling and I could not understand what she said and asked them to mail me something explaining what she was calling about.  She said that she would put a note on the file that I would not give them a death certificate and didn't say that they would send me any explanation about this call. A lot of back ground commotion was noted during the call - calling mill?

Probably a criminal debt collector trying to collect an imaginary debt.

Man with very thick accent called looking for someone who's name I couldn't understand.  Told him no one by whatever he was saying lived here.  Asked me if I had a number for whoever it is he's looking for. I told him no. Lots of noise in background.

When I call the number it the answering tape is Credin Resource Management
