I just tried google voice recently, and i just can't make a call from my cell phone. Every time I select one of my contacts on my phone and dial out with google voice, it first display the right number but it soon will change to 602-633-4000. I don't get it. However, i am able to make a phone call with google voice on the computer, it will connect my phone and then dial the right number. How do you guys dial out from your cell phone with google voice?
