I'm sorry, but you are mistaken. Your voice is <i>not</i> transmitted over an IP network with Google Voice. That's why it's <i>not</i> VoIP. There are no semantic games involved. Since I feel like I've beat this to death a few times before, I'll just point you to this: <a href="http://www.itworld.com/print/75774" rel="nofollow">http://www.itworld.com/print/75774</a>.<p>And yes the Wikipedia entry for Google Voice is mistaken. I should probably fix that for them...
