No, its supposed to be used in place of the VZW minutes over the data connection. Hence, why the new Nexus one does not require a cell phone connection to make calls when you use WiFi. When I had the OEM ROM on my phone it went through Google Voice and didn't use my minutes at all. The calls also appeared in my outgoing call log on GV. Now my outgoing calls do not appear there nor does my GV number pop up on the caller ID.
