Q: WiFi calling breaks phone when active

We have 3 ATT iPhone 6 in our house, and 2 work great with wifi calling. 

On mine, if it is enabled AND active the phone becomes unusable.  Outgoing calls get a "unable to complete" message, incoming calls immediately goto voicemail after a brief flash of the call on the screen.  Have tried EVERYTHING.

-  All 5 suggestions on this page

- Wiping device and restoring

- Wiping device and trying as a new phone

- Using wifi at my work where other phones can use this, though my home wifi works fine for 2 of our devices.

iPhone 6s Plus, iOS 9.0.2
