Google Voice has little to do with voip. It's really just a robust call forwarding system.
Currently using your GV number prevents you from using the the iPhones Visual Voicemail and receiving texts via the built-in SMS app. While GV offers some interesting features, it significantly impacts how the core phone functions are utilized. A clean implementation of GV would require you to replace your phones dialer and SMS with Google apps. I can understand why Apple is hesitant to move forward on this.
I'm hoping tat Google can partially address these problems by forwarding SMS and VM messages directly to your phone.
hopefully, but sounds like there are some people who don't want us to have it..

WASHINGTON--The Federal Communications Commission will open an inquiry into Google Inc.'s phone management service, asking how the service works and whether the Internet giant is restricting any calls, according to people familiar with the matter.
An FCC letter to Google is expected to be sent later Friday, they said.
At the heart of the inquiry is the allegation that Google may be blocking calls to certain numbers with high access charges.
Google reserves the right to restrict outgoing calls to some phone numbers, including adult chat lines and conference-call centers, which charge higher access fees to carriers. Blocking such calls reduces Google's expenses for the service.
AT&T Inc. has cried foul about the practice, saying Google is violating rules that were designed to ensure that phone companies will connect all calls. Earlier this week a group of lawmakers asked the FCC for an investigation into the matter, saying the practice could hurt rural customers.
AT&T has also accused Google of violating open Internet principles, which are designed to ensure that consumers can access all legally available content and attach any external devices they wish.
The FCC is scheduled to vote on an open Internet rule later this month. FCC officials consider the questions about Google Voice to be separate from the open Internet rules.
Google Voice allows people to link all of their phones to a common number and manage calls and messages through a single Web site. The service can also be used to send and receive phone calls and text messages.
Google says its phone management service isn't subject to common carrier telephone rules because it is free and consumers can use it only if they have a traditional telephone line.
AT&T and other carriers say they don't want to pay high access charges either. They were rebuked by the FCC several years ago for blocking such calls, but the FCC said common-carrier telephone companies can't pick and choose the numbers they will patch through and those they will block.
