Just got a call at my work number from this number - after I answered, they hung up.  When I called it back, a machine said "Thank you for calling Canada Christian College" so I hung up.

called house phone left no message

Answered.  Asked for someone else.  I said sorry you have the wrong number. Clearly they just getting from a phone book. Said his name was Jack Jamison calling for some donation to Children's breakfast and lunch program.  Which I know is a free service in our community. He then proceeded to ask for address and number to contact at another time. I said no thanks and hung up.
