Alright, I need someone to help me out as I'm starting to get a little confused.

The N900 supports "Google Talk" calls apparantly, at least it appears integrated. I can go to the dialing pad, pick call type, and select my Google Talk account to make a phone call. However when I do this, I get a yellow error bar saying "Incorrect address." and no call is made.

Now, I just recently received a "Google Voice" account. It was my belief that Google Talk was Google Voice, but I guess it is not? Am I unable to directly use Google Voice integrated in the N900? What does it take to get Google Talk to work then? Voice, Talk, so confusing!
