Teams Phone Numbers Mysteriously Unassigned

I've also seen this happen numerous times over the last 6+ months. I've assumed it was due to MS allowing us to assign too many licenses over what we have purchased, so it randomly unassigns the extra phone number.
The latest issue is that many, but not all, of our Teams phone numbers have been unassigned and the license is also unassigned. I have a ticket in with MS but they don't have a fix yet. I've also tried running the audit log to see if I can find which users have been unassigned based on date, but the logs ARE NOT WORKING. So we are waiting for a response from MS.

hellohello I forgot to respond to this. We found our solution. We've got two OC operators. The second one was wiping the numbers as it thought it owned the user accounts the numbers were missing for and wiped them out. Might be worth checking if you've got a similar setup.

There doesn't seem to be anything logged anywhere for any of it though which is a big hole in my opinion.

Hi mate, we are having similar issue with two OC operators one from USA and new one from UK. The UK numbers keep getting unassigned. Did you manage to find a solution for this?

  It was because two different operators were connecting. The 2nd one overwrote the first so unassigned numbers they didn't 'own'. We fixed by not using two operators. The fix would be the 2nd operator only updates accounts/numbers they have authority for.
