We have a real need to be able to control which extensions can see which extensions in the directory.
We would like the ability for Departments to only be able to see their respective extensions.
What we now have is temporary employee's or assistants in some departments being able to see the extension, email, and mobile of the CEO of the organisation.
You could even use Extension Groups to quickly roll out this feature, but I can not stress the importance of being able to hide VIP extensions from temporary or hot desk employees
