I seem to have inadvertently fixed this issue on my Sony XZ1
Within the phone app, I went to 'Settings' | Calls | 'Accessibility'
I noticed TTY mode was set to 'off'. I set it to 'TTY full' and rebooted the phone.
Within the phone app, I can now see 'Wifi Calling' as an option within 'Settings' | Calls |
I'd be interested to know if this works for anyone else?

I suspect it's just coincidental to O2 fixing the issue on their servers.

I have flashes it with the O2 firmware and the issue does appear to be more network sided than software on the phone.
Very intermittent connection to WiFi and 4G calling, will connect but that is not always the case and have to reboot multiple times to get it back.

This is definitely a network issue. So many people have this problem with O2 aand unless all these customers have the same software issue it points to a network fault.
Perhaps @viridis knows whether Sony have said there is a software fault on the X1?

No fault that I'm aware of, and I have asked about this.
Unfortunately as I was afraid.
