Microsoft has sent out an announcement on PowerShell changes for setting and removing phone numbers in Microsoft Teams:
In summary, these commands are being deprecated “The retirement is planned to begin in early April and be complete by mid-April.” :
and Set-CSUser can’t be used to allocate phone numbers either. I’d been allocating numbers with the Set-CsOnlineVoiceUser command. The replacement for this is:
Set-CsPhoneNumberAssignment and Remove-CsPhoneNumberAssignment
They run under the MicrosoftTeams module for PowerShell, but you also need to make sure you have the latest version. If you don’t have a version that supports this new command, you’ll get the error:
Set-CsPhoneNumberAssignment : The term 'Set-CsPhoneNumberAssignment' is not recognized as the name of a cmdlet,
function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the
path is correct and try again.
At line:1 char:1
To update, run the command:
Then try the above cmdlet again. If you’re feeling really brave, you can update all your modules with:
Disconnect or restart PowerShell or you’ll get problems running the new cmdlet if you had it connected while updating.
The new cmdlet Set-CsPhoneNumberAssignment doesn’t work exactly the same way as the old cmdlets. Read the documentation for more details
Set-CsPhoneNumberAssignment -Identity [email protected] -PhoneNumber +61987654321 -PhoneNumberType CallingPlan
The options for -PhoneNumberType (required) are DirectRouting, CallingPlan and OperatorConnect.
I’d suggest testing and migrating soon, before you miss the April deadline of the command being dropped.
