So the long and short of it is, at least as I understand it, that using Google Voice does nothing to cover your tracks when you use an iPhone, other than instead of a provider's real number, it shows a bunch of activity using your Google Voice number

At this time there is no native app from Google to accomplish this with an iOS device (iphone, ipad, etc.) or an Android device.
Depending on your pattern, time of day, and frequency of calls I am not certain one would have to explain anything in a divorce deposition about calling a GV number.
It is also possible to change your GV number as often as you wish for a $10 fee per change or for free by creating new Google accounts.
