In my Ticket 19069450510 i asked for a chance to set voLTE and wlanCALL Settings.
They told me to set up an feature Request.
It would be a nice to have to enable voLTE and wlanCALL from MDM.
We use only devices from Android one Concept from Goolge - Stock Android
The Settings for voLTE can be found under:
Settings->mobile&network->mobile->more->Enable 4G LTE-mode
wlanCALL:
dailer App -> settings -> call Accounts -> WLAN Call - Enable
dailer App -> settings -> call Accounts -> WLAN Call - Enable -> prefer wlanCALL
