Teams Phone Numbers Mysteriously Unassigned

Over the last  2 weeks or so, we've noticed a handful of our Teams phone numbers which were assigned to users, become Unassigned.  We have no automation in place - everything move, add or change we p...

Thanks MarcR727 for your feedback! I did get a root cause from Microsoft that it was a bug fix: The AD attribute OnPremLineUriManuallySet bit was false due to the bug. There was a bug in the legacy TAD cmdlet because of which assigning OC number did not set OnPremLineUriManuallySet flag.

Good to know, thanks Denny. I have a case open with Microsoft for this issue but they didn't mention that. I'll add your info to the case notes.

    wombattler Any further updates on this? We recently moved to teams calling and noticed this started happening.  Our Provider logged a job with Microsoft, but there has been no definite answer on the issue or solution.

      BrendanNZ We are still seeing the issue (phone numbers randomly unassigned). I logged a case with Microsoft but then it didn't reoccur for two weeks, and they closed the case.

        We are only now experiencing the exact same random issue with our Teams Direct Routing.

         

        Over the last couple of days our users have had their numbers unassigned. We can re-assign the number, however it disappears again after about 15 minutes.

         

        We have over 360 users, all with Office E5 licenses and have been working using Teams for over 3 months.

         

        Dialpads are now missing in Teams Applications

        Audio Codes handsets have signed out

        Internally Teams is working fine, however we cannot make/receive to/from external due to the numbers being unassigned

         

        Does anyone know how to resolve the issue?

      BrendanNZ no further issues experienced here, after Microsoft's bug fix.
