This is an automated spam call that left a pre-recorded message on my voicemail. I'm on the Do Not Call registry, so this call was probably illegal. A man with a used car salesman's voice says, "you owe it to yourself to find out how to make unlimited income from home! Press 2 now to find out how to generate income streams, [blah, blah, blah.......] or press 9 now to be removed."
I pressed delete, and nothing more. I imagine you would incur a nasty charge and/or an awful, live sales pitch if you do anything besides hang up or delete.
