Get-CsDialPlan to be retired

Microsoft announced in MC950879 that they will remove the Get-CsDialPlan Cmdlet and the DialPlan attribute from Get-CsOnlineUser.

After the change, you will still be able to check what DialPlan (and normalization rules) a user has assigned using Get-CsEffectiveTenantDialPlan.

The DialPlan is automatically assigned from a user’s UsageLocation. However, after the change, you’ll only be able to see what rule(s) are matched but not which dial plan the rule is a part of. (Test-CsEffectiveTenantDialPlan)

I recommend exporting the default dial plans and normalization rules before the Cmdlet is removed in case you want to have a complete overview of all default dial plans:

Get-CsDialPlan | ConvertTo-Json -Depth 99 | Out-File C:\Temp\TeamsDialPlans.json -Encoding utf8
