AT&T announced a while back about a new service they were going to offer called NumberSync. I honestly just blew it off as another gimicky service that was carrier based so most likely horribly implemented. This week the feature has been enabled on iOS devices along with... WIFI CALLING!!!! These two new features go hand in hand and use each other to work. Let's take a look at setting this up since it can get a bit confusing and took me a few tries to get all figured out (I also just ported my Google Voice number back to a carrier since I have now given up on GVoice after 2+ years of trying to make usable in a multi OS environment). Note: This post will be refined w/screenshots shortly.. :)
