Who called from 2397851905

Received call on my cell; they didn't leave message.

They called my mom's cell phone and hung up without leaving a message.

I answered hello,  then there was a pause and a voice that sounded recorded said this is Ray. I did not speak,  the voice said are you there,  and then hung up.  Surely a scam.

called my cell.  said his name was Ray and was asking for donations for the police department to help poor families.

Called both my home phone and cell phone numbers.  Just silence when I answered.
