I am a Google Voice user, but I have not used it much for outbound VoIP calling. My friends often ask me why I use it since its primary benefit to many users is low-cost long distance calling. I use the system primarily to route inbound calls to different phones that have better coverage or battery life than whatever handset I am carrying. Since AT&T coverage is spotty at my home, and I don’t like to carry my phone around the house, I try to route inbound calls to my landline so I can hear the ring on all the extensions.
Google Voice also lets me send SMS messages seamlessly continuing a conversation thread between my home PC and my cell phone when I go mobile. I don’t use the service to make outbound calls mainly because I don’t have challenges with my long distance bill as most of those calls are domestic and can be done within my cell plan as free mobile-to-mobile minutes.
Occasionally, I will forget to deactivate a phone number I no longer wish to route calls to when I am on the road. Since there has been no Google Voice app available for my iPhone, I put a browser shortcut on my home screen so I could quickly access the Google Voice website and change the settings when I am away from my PC. Today when I did that, I was surprised and delighted to find that my experience had completely changed.
Google Voice is now a web app. A web app differs from a website because it creates a unique experience for every session and visitor. When I interacted with the web page, Google Voice provide my device with a newly coded page which told my phone to update the icon on the home screen shortcut from a picture of the Google Voice web page to a neat, streamlined Google Voice icon.
Google developers used HTML5 to support outbound voice calling and avoided the Apple App Store approval process, which previously led to a rejection of the downloadable version of the application. A phone number in your Google contact list that is accessed through the new web app – or entered in the web app’s dialer – will connect through the standard iPhone calling function.
The call will actually use the AT&T voice network to connect the call but route through Google Voice and appear to the person you are calling as if the call came from you Google Voice phone number, hopefully avoiding some pesky international long distance charges you might incur. Oddly, though, to do that routing through Google Voice, the phone appears to dial a number with a totally different area code than the one you are actually calling.
