Is GoogleVoice possible on 8350i

[Thinkster]

I have an existing Google voice account, and just installed the app on the 8350i. However when using the Dialer to try to make a call, it always says, "The number or code you dialed is incorrect..."
The number it's trying to call is +150442330482 (which apparently is the access number and changes each time). That of course is not the number I'm trying to call though.. What are the settings I need to do on my phone as well as the Google voice account setting on the web?

I used googlevoice couple times using my 8350i without a problem.
I didn't have to make any change in setting. Just installed the program, dialed (international), and it worked.
