know for sure if HD Voice is working

I'm curious to find out if there's a way to know for sure if/when HD Voice is actually working during a voice call apart from sound quality or coverage map. I think it should be and maybe it is but it doesn't really sound like it. We have an iPhone 7 and an iPhone SE both with LTE Voice and Data enabled and an iPhone 5s (LTE Data enabled; not LTE Voice capable) as well as a landline. I turn the Wi-Fi off on the iPhones so I can see the cellular network status indicator. The iPhone 7 and iPhone SE don't behave any differently when a call is connected between them than when either has a call connected to the iPhone 5s or the landline. The LTE indicator stays on throughout the call. It doesn't drop down to 4G like it does on the iPhone 5s. That seems to indicate to me that "VoLTE" is able to maintain LTE data during any kind of voice call whether it's HD Voice or not so is there another intuitive way to determine that apart from sound quality and/or coverage map.

If you are using Wifi calling, HD voice is enabled on he phones.  

Without VoLTE and HD calling, Wifi calling is not possible.

That's the ticket! I successfully enabled both Call Protect and Wi-Fi Calling on the iPhone 7. Also successfully verified Wi-Fi Calling works. Killed the cellular and Wi-Fi radios with Airplane Mode then re-enabled Wi-Fi. Wi-Fi icon came back on and then changed to "AT&T Wi-Fi" and successfully placed some test calls via Wi-Fi calling. Then these calls showed up on the bill the same way as any other calls except call type is "PVWIFI".
