Creating a Teams phone using a Wi-Fi only Android or iOS phone in kiosk mode.

Vitor Pereira did you go down this rabbit hole? I have attempted this with about an 80% success rate on the Samsung Galaxy XCover Pro, but the one thing I need to work, inbound calling, doesn't. So, success is really 0%... The phone rings, but only presents the inbound call screen if the device is on and Teams is open. Otherwise, you cannot answer the call.

I'm at my wits end right now and would do anything for help/advice.
