Wisconsin:

Wisconsin law expressly authorizes civil damages for violations and allows recovery of the greater of actual damages, $100 for each day of violation or $1,000, along with punitive damages, litigation costs, and attorney fees. Wis. Stat. § 968.31.
Recording a communication without consent is criminally punishable by up to six years in prison and/ or a $10,000 fine. Wis. Stat.§ 939.50.”

Maybe we should up the fines for prank phone calls to the death penalty - as a deterrent.... :)
