Weren’t there some phones where VoLTE was very difficult to enable? I remember some where aftermarket ROMs would not work with it because it was actively blocked/broken by the manufacturer. I’ve also seen some models where it worked on Telstra but not Optus.
Hell, I can demonstrate a 100% compliant WiFi setup which prevents making 000 calls while connected to it. This happens while allowing all traffic through. I think it’s a patchy RFC6877 implemenatation in Android, but I haven’t narrowed it down just yet.
The number of times I’ve seen my phone fall back to 3G voice in the Melbourne metro is unbelievable. I’ve heard it doesn’t even work properly when calling between Telstra and Optus.
It’s a common issue with custom ROMs. Samsung phones cannot get working VoLTE on any ROM that isn’t based on OneUI, and many models from other manufacturers don’t work either. There are tools like Pixel IMS that can theoretically allow you to manually enabke VoLTE, but I’ve never seen it consistently work on anything other than Google Pixels.
