Who called from 4168487845

I called the number back and a message said something about donations and support, it then gave a toll free number to call (800)379-2068. I did call and the system gave me an option to remove my number from their list.

I entered the above number into the search field and here is a link http://800notes.com/Phone.aspx/1-800-379-2068 People report it's a "Cancer Recovery Program"

number reads on caller id,but when prompted by answering machine, no sounds and then hang up.
