Gotcha. I'm thinking my perception of GV was a bit different than reality. I thought it WAS a VOIP type deal, even when I have a 3G signal, I thought it made those calls through the 3G, thus through the web. I need to research things more thoroughly. Thanks!
FYI Gizmo5 has been bought by Google.
Actually, you can accomplish this using the free Google Voice callback app, a gizmo5 account (or any SIP number) and Fring (or any client that will allow SIP). I saw this following thread and just set it up. I was able to make calls using Airplane mode and wifi only.

Here are the steps that I followed:
1. Set up fring for SIP calling. I entered my gizmo5 id, password and proxy server ( proxy01.sipphone.com) information.
2. Downloaded and installed the free Google Voice Callback app from the Market.
3. Entered the gizmo5 number in the GV Callback app setting and entered my Google Voice id and password.
Now when I dial any number, a menu pops up asking if the call should be made via the callback app. When I select that option, it calls back on Fring and after I accept that call, it connects the other party.
It was fairly straight forward to set up and the process works almost seamlessly (except for the two extra clicks/touch).
Alternatively, you can also pull up the google voice web site on your browser and dial from there too and accept the call on Fring. But it's much easier with the callback app.
