It's for trade publication subscriptions. Dial them back and press 8 to remove your number from their calling list.

They call everyday. They hang up after I say "hello"!

this person/company calls my office every day @4pm.  the id says "Lafollette" .. when i answer, no one ever speaks.  i re-dialed the # and got an auto attendant announcing that it is for free subscriptions.  i followed the prompts to refuse any subscriptions.  now maybe they will quit calling.
