@tuXut before they broke it (global issue on Qualcomm devices) I had volte working on a OnePlus 7 Pro on halium10. So I believe it will work on these devices. I'm sure they are working further on it for example sms was broken with Volte working and the phone app was going a bit crazy.

@Keneda Device came with android 13, It was ported on halium 11. It works
