• While a number is migrated from Direct Routing to Teams Phone Mobile it is out of service, so Microsoft advises coordinating with the operator before starting. in context
• For Direct Routing numbers assigned online, the Teams Phone Mobile operator performs the migration at an agreed date and time, which may mean removing the number from the tenant and adding it again as a Teams Phone Mobile number. in context
• For Direct Routing numbers, the admin checks whether each is assigned online or on-premises; if OnPremLineURI in Get-CsOnlineUser output holds an E.164 number, the number was assigned on-premises and synchronised to Microsoft 365. in context
• For Direct Routing numbers assigned on-premises, the admin clears the number with the Skype for Business Server command Set-CsUser -Identity <user> -LineURI $null and confirms the change has synchronised to Microsoft 365. in context
• Removing a Direct Routing phone number can take up to 10 minutes to take effect, and in rare cases up to 24 hours, depending on configuration. in context
• After a Direct Routing number is unassigned, the admin removes the user's online voice routing policy with Grant-CsOnlineVoiceRoutingPolicy -Identity <user> -PolicyName $Null. in context
• To move a number from Microsoft Calling Plans to Teams Phone Mobile, the admin removes the number from the user, the operator ports it onto an eligible SIM-enabled wireless voice plan and uploads it to the tenant, and the admin then assigns it. in context
• To move a number from Operator Connect to Teams Phone Mobile, the admin removes it from the user, the existing Operator Connect provider removes it from the tenant, the Teams Phone Mobile operator ports it onto an eligible SIM-enabled wireless plan and uploads it, and the admin assigns it. in context
• Teams Phone Mobile numbers reach the tenant by the operator uploading them after it completes the order; admins then see them with the provider under Voice > Phone numbers and assign them to users. in context
