Managers' Global White list
The administrator can define a global whitelist of calling numbers and ranges that should NOT be filtered by Assistants when calling a Manager. In this list you can add voice mail numbers, emergency services and any type of private numbers.
You can just add comma-separated numbers in E.164 format or ranges with a prefix followed by “!” wildcard. See below sample:

This white list is applied to all Managers, and it is added to the personal whitelist directory which can be populated by each Manager on its own.
