hello, the volte was closed in recent updates. I've come across some of these issues and done some research. the solution is as follows; switch to the test application (CIT) by clicking on Settings / My Device / all features / kernel three times. open the additional tools / modem test tools / MNB configuration installation and activation tool from the menu in the upper-right corner. Change and test the MNB settings as shown in the picture, select and activate the MNB that opens the volte.

load the old version rom install. for example, you can install 9.12.19. then set the mbn setting. then update the latest version to the top.
