When creating new user accounts in Cisco Unity Connection, you want to allow users to add alternate extensions to access their voicemail. In which area of the menu do you do this?

The Class of Service configuration contains an explicit permission toggle that allows or denies users the ability to add alternate extensions themselves via the Messaging Assistant or telephone user interface. Because CoS governs all end-user feature access rights, enabling this setting in the CoS is the correct and required step before the capability becomes available to any user assigned to that CoS.

Class of Service membership is where individual users are assigned to an existing CoS - it is an association mapping, not the location where feature permissions within the CoS are defined.

User templates supply default property values applied at account creation time but do not contain the feature-permission toggles that control self-service alternate extension access.

Contact templates configure default properties for Unity Connection contacts, not user accounts, and have no settings related to alternate extension permissions.
