WATTS, or toll free, calls are charged per minute. Most WATTS lines are up to $0.40 per minute. All WATTS lines have ANAC functions which grab your phone number before the phone even rings. They get a detailed report of each and every person who calls.
Multiple calls to the same phone number, WATTS or residential, are considered harassment. Look in the front of your phone book...it's outlined right there. You're not helping...in extreme cases, they will bring in the authorities.
