Does anyone have WiFi calling working?

[kage00]

I've tried the advice on this thread https://forum.xda-developers.com/xiaomi-mi-10-ultra/help/wifi-calling-t4157029/page2 and have managed to enable the settings for wireless calling, but when I have no mobile signal and am connected to WiFi the phone won't allow me to make calls, it says something like "unable to make call, please connect to a WiFi network"
Even though I'm connected to WiFi...
Has anyone else had any luck with this? I'm using a xiaomi Mi 10t, but I imagine it'd be the same for xiaomi Mi 10t pro.
Any help would be greatly appreciated

VoLTE and VoWiFi are working fine for me.
I bougt the phone from the same carried that I am using.

Thanks for the reply, yeah that's what I've found while I've been researching, it has to be carrier enabled for the phone. We can turn on the settings from the phone but if they haven't enabled it (usually in their branded firmware) it won't work...

I activated VoLTE and VoWiFi on my gf's Poco with the codes and the options show up but only VoLTE works.
I verified that it works, it stays on 4G while in call. When calling while on WIFI only it shows an VoLTE HD icon but VoWiFi is not working.
Don't feel to root her phone and try the other things.

VoLTE *#*#86583#*#*
VoWIFI *#*#869434#*#*

Thanks for this. I just spoke to my phone carrier yesterday and they told me that WiFi calling isn't supported from their end... So it looks like I'll be changing carrier, I need this to work
