Fed courts say don't tax VOIP
States like New York are trying to make the case that it's just like any other phone service, but that's not even remotely true. Heavy regulation of traditional phone service is justified because it's essentially a limited resource and a natural monopoly. It's not like every company can string up a phone network. Cable TV is regulated under the same premise.
Have you looked at your phone bill lately? I'm absolutely astounded at the number of taxes. They take up one entire page of the bill now. It's ridiculous. The only thing that has kept me from flipping to Vonage is that, for the moment, I can't carry over my phone number... yet.
