Query: VOIP hits mainstream phone service

I bought this plugged it in to my network then plugged a cordless phone in and started making phone calls. The rate of 3.9 cents a minute was much cheaper than my other second line and its about the same quality so I canceled my second phone line. I guess this is where voice over IP is going. Works just like a regular phone... that's the way it should be...
