After a couple weeks of trying to figure out why I cannot initially enable Wi-Fi calling, I was able to get a workable solution. A little bit of backstory first. There are five lines on my account, all of which have Smart Limits enabled. Turns out, Smart Limits disabled vo LTE... This however is required for Wi-Fi calling.
Tldnr, disable ATT SMARTLIMITS if it is enabled, full power cycle (power down not just reset) and try to set it up again.
* this was on a stock s7 no root, no custom rom, full carrier bloated phone.
