I'm not talking about "Allow Calls on Other Devices", which we have since iOS 8/OS X 10.10 Yosemite. I'm talking about the *new* feature that allows your other devices to have access to the Wi-Fi Calling on iOS 9 on your iPhone—even if the iPhone is far away or powered off. This article explains the difference.Works now....View attachment 598293

"AT&T’s NumberSync feature is very similar to the Continuity functionality that Apple currently offers. Mac, iPad, and iPod touch owners are currently able to make and receive telephone calls via Apple’s Continuity feature as long as said device is connected to the same Wi-Fi network as the iPhone that holds the number. The NumberSync offering essentially serves up the same level of functionality, but doesn’t require the device in question to be connected to the same wireless network as the iPhone. Basically, WiFi calling via your AT&T account."
That is coming to AT&T on iOS 9.2 (already available on Sprint and T-Mobile on the current iOS) and I was wondering if a future version of El Capitan might support it too.
