Call2Teams - Customers
TABLE OF CONTENTS
Currently the Sync process does not remove the Resource's account's Direct Dialling In (DDI) and calling policies.
Customers must remove these from the Microsoft Tenant if they are planning to re-use the DDIs for other users.
Remove the Resource Account's DDI's from the C2T portal first.
Run a sync and then remove the DDI's and calling policies from Microsoft Teams using the PowerShell commands below:
Connect to Microsoft Teams PowerShell
Connect to Microsoft Teams PowerShell Module as described in the link here.
Enter the following command:
Set-CsOnlineApplicationInstance -Identity "Email Address" -OnpremPhoneNumber $null
To confirm the script worked: Navigate to Microsoft Teams Admin Portal >Voice > Resource Account > Phone
The number should no longer appear.
Enter the following commands:
Grant-CsHostedVoicemailPolicy -Identity "Email Address" -PolicyName $null
Grant-CsOnlineVoiceRoutingPolicy -Identity "Email Address" -PolicyName $null
Grant-CsTeamsCallingPolicy -identity "Email Address" -PolicyName $null
