From Admin Portal, you can manage specific resources, such as stations or agent login IDs, regardless of their association with a user. Therefore, for each resource, the resource identifier must be explicitly specified.
Each resource has the Location, Org Unit, and Public Resource fields.
From System Admin, you can manage Location and Org Unit. The location and org unit pair is called a group. Each group maps to extension ranges and templates.
Public Resource specifies whether a resource is public or not. To show resources to all the users, you can set Public Resource to Yes.
