Caller proposed to be from Blue Cross, Blue Shield (Health Coach).  Caller asked for my telephone number and address in the course of the call.  I refused.  I told her I would call the number on Blue Cross literature, I'd recently received.  Why would the company use a random number generator if their calling a list of clients.

Call appeared Tuesday, January 6th, 2009, not sure what time. Let answering machine pick up as it showed "caller unknown" on Caller ID. A man said "hello" once and then disconnected.
