On the telecom side there are currently several features that used to be available on premise in Lync/Skype that are still missing from Teams as a phone system replacement. Analog support via ATAs is still unavailable, though could most likely be an improvement to the SIP Gateway. Additionally, things such as Private Line are missing as well. These are greatly hindering our Teams adoption as our phone system replacement, and it seems like several items from the phone system side don't show on the M365 roadmap, but are in the pipeline. Are these actually in the pipeline?
