Symptoms
When you make a Skype call to a call queue number in Microsoft Skype for Business 2016, you may notice that the toast window shows SIP URI instead of the call queue name.
Resolution
To fix this issue, install the March 5, 2019, update (KB4462190) for Skype for Business 2016.
Note Before you apply this update, make sure that you create a Group Policy Object (GPO) to add a new DWORD registry key EnableCallQueueDisplayName and set the value to 1 in any one of these registry paths:
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Lync
or
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Office\16.0\Lync
Alternatively, you can enable this by creating a custom policy entry and add it to the client policy:
$x = New-CsClientPolicyEntry -Name "EnableCallQueueDisplayName" -Value "true"
Set-CsClientPolicy -Identity "<ClientPolicyName>" -PolicyEntry @{Add=$x}
