Internet calling

I'm always looking for a way to lower my monthly bills, as I'm sure you're always looking for a way to lower your overhead. Something I've been investigating lately is Internet phone service as a replacement to a land line at my home.  I ran across this article on Internet calling at the New York Times. The article reviews several Internet calling services and lays out their benefits and drawbacks. I'm not sure any of these services are ready to replace a phone line at a business, but the technology seems to be advancing quickly. It might be a subject worth keeping your eye on for some future overhead savings at your business.
