Hi,
Im struggling with changing the CallerID of the users in our tenant.
I followed the steps from https://docs.microsoft.com/en-us/skypeforbusiness/what-are-calling-plans-in-office-365/set-the-calle...
I've assigned a CallingLineIdentity to all users, but the CallerID doesn't change. When you make a call the personal number of the user appears. The only CallingLineIdentity policy that does work on the users is the Anonymous policy. When I assign a policy with the servicenumber, it changes back to the personal number of the user.
I've tried setting the CallingLineIdentity back to $NULL and then back to one i've created earlier but there is no result.
Can someone help me out on this one? :)
Here is a short transcript of the commands I've used to achieve this:
To make the CallingLineIdentity:
New-CsCallingLineIdentity -Identity "IDNAME" -CallingIdSubstitute "Service" -ServiceNumber "PHONENUMBER" -EnableUserOverride $false -Verbose
To assign the CallingLineIdentity:
Grant-CsCallingLineIdentity -Identity "USERNAME@DOMAIN.COM" -PolicyName IDNAME
To check if the CallingLineIdentity is assigned:
Get-CsOnlineUser -Identity "USERNAME@DOMAIN.COM" | FL CallingLineIdentity
