-
 When you assign a policy to a group, you specify a ranking for the group assignment. This ranking is used to determine which policy a user should inherit as their effective policy if the user is a member of two or more groups and each group is assigned a policy of the same type.
 
 The group assignment ranking is relative to other group assignments of the same type. For example, if you're assigning a calling policy to two groups, set the ranking of one assignment to 1 and the other to 2, with 1 being the highest ranking. The group assignment ranking indicates which group membership is more important or more relevant than other group memberships regarding inheritance.
