Kurt - this is an excellent question, and one which I feel MS need to provide much more clarity and guidance on. My initial view was not to Intune enrol Teams IP Telephony devices. But we have changed direction and we will Intune enrol these devices. Why? Because we have a number of Conditional Access policies that apply to "untrusted" endpoints can adversely affect the user experience for accounts signed into a Teams IP phone. But by having these devices in Intune and marked as compliant, they are considered "trusted" so the conditional access policies don't apply. Word of warning, getting this working correctly is not easy and has required a lot of trial and error, and various issues along the way. We've already logged 2 PS tickets to try and get this working, and are currently on the third PS ticket. I think we are quite close to a working solution. Word of warning: Meeting Room SKU includes Intune licence, but Common area SKU does not, which is an additional frustration.
