I believe this to be wrong. I was pretty sure the only way to get google voice to make calls over a wifi connection was to use a an app like Grooveip. That is the app I use to make wifi calls with my phone, and it works pretty well. Reason being that google voice has no built in dialer. When you use google voice on your phone's default dialer your call goes out across your carriers data not wifi. When you run an app like Groove ip it will in fact connect to wifi with your google voice account and place the call over wifi. It is a payed app. There might be other apps that are free in the market, but I know for a fact Groove ip works.
