Is EE testing VoNR?

PHK

When I make a call while connected to 5G, my iPhone normally switches to 4G for VoLTE and then back to 5G.

But I've noticed that in one particular area the phone stays connected to 5G throughout. 

I know VoNR hasn't launched but is EE testing it?

Just to close this up. I asked elsewhere!

Yes EE are testing VoNR in some areas and estimate a launch along with 5G SA in H2 of this year.
