Let user choose their CallerID

Hi,

I followed the documentation regarding CallerID Policy : https://docs.microsoft.com/en-us/skypeforbusiness/what-are-calling-plans-in-office-365/set-the-caller-id-for-a-user

I have 2 CsCallingLineIdentity policies :

• Global : which enables the user to set/enable anonymous calls via the webUI : https://admin0a.online.lync.com/lscp/usp/pstncalling 
• Standard : which sets the callerID to our service number, I have also set to true the switch "-EnableUserOverride" to set anymous calls as well from the WebUI

Is there a way to let the user choose their CallerID between their Own phone number, the Service number or anonymous ?

Thanks for your help,

Antoine.
