Hi jxace
Our root cause was someone had defined an extra sip port on the hosted SBC trunk in our Direct routing setup
The hosted SBCs were load balancing between 2. Unfortunately though, the fqdn in the contact header means this caused problems with TEAMS.
Our SBC provider disabled the 'bad' port - then all calls were fine in the respect of any ACKs or re-invites etc between TEAMS and the SBC.Not sure if this helps but good luck
Can you please check in case MusicOnHold Capability is enabled on the policies? In case yes please try to disable the same and test the feature. This should fix it.
Let me know outcome post which we can have future insight from Internal Microsoft Team.

This exact issue was happening for me. I disabled the MusicOnHold capabiity and the issue no longer persists. This is a nice workaround, but at the cost of hold music.
Also note, that when you disable hold music, it takes several hours for the change to take effect.
