Teams Voice with Direct Routing and NonUniqueOnPremLineURI
jangliss I would suggest running "Get-CsOnlineUser -Filter "lineuri -eq 'tel:+11234567890'" as this could also be not assigned against that variable. Looking forward to seeing what you get by running that command.
I should have mentioned that, I did that command, and no records returned. This is sort of expected because it couldn't assign the phone number to a user due to the duplicate number error.
- have you checked to see if the number was assigned to a resource account?
Eric MarsiYep, not assigned there either. These are extension based numbers, so tel:+11234567890;ext=112233 and no resource accounts have those numbers assigned. These are new phone numbers being assigned, originally the numbers were tel:+11234561000 through +11234569999. Users having numbers moved to +11234567890;ext=<employee id>. The prefix number was never used elsewhere.
That said, we have this error showing up on 3k other users, so it's not likely a real duplication issue, which is why I have a case open with Microsoft and their troubleshooting has been the same thing I'd already done. We do have about 100 users that have the same prefix, with different ext= values that are syncing without issues. Comparison between those users and a handful of broken users shows no observable differences other than the values expected (guids, names, phone numbers, etc)
