So y Xperia 1 II ims registration issue

[Wass]

Good evening

I have just changed the phone fro Xperia 1 to Xperia 1II, and cannot get wifi calls, as IMS not register, hence VoLTE, WiFi calls video over wifi don't work. It used to be fine on Xperia 1, i tried my sim also with Xperia XZ3, it doesn't work too, Iphone 7 - work, iphone 11 - work.

Thanks in advance
