Wifi calling Xperia 1 not working

[ATNeuromonkey]

I recently got the Xperia 1 from O2 and for a couple of days the WiFi calling was working now it is not. I have done many restarts of the phone, checked the firmware, but have had no luck getting it back i.e. there is no options in the networks settings available for it anymore. Can anyone help?

Hi, I believe this is being looked into by the software team right now and once more info is available, @Chris_K will be updating a currently running thread.

Someone else had an issue with this. Check the thread here https://community.o2.co.uk/t5/Android/Sony-Experia-1-has-no-WiFi-enabled-calling/m-p/1227614/highlig...

I will also tag @Chris_K  to ask if it has been fully approved yet?

Looks like the last software update removed the features, I noticed when it arrived on the 31st May it was permitted, now the options have gone

If possible check enabled on your account then on the phone dial *#*#4636#*#* if this does work then choose phone information. Toward the bottom check if VOLTE and WiFi calling are provisioned, button to the left is no and the right is yes.

Are you sure the android WiFi Calling is enabled on the device it should show as being provisioned still.

Maybe call customer service and ask.

This appears to have been fixed at O2's side as I can see both Wifi and 4G calling in the call settings now

I had it return briefly for 2 days and now it has gone again.
