Which Avaya IXT™ Messaging admin feature supports not forwarding callers to their destination, even if the PIN is correct, when they are calling…

The PIN schedule is a specific security feature within Avaya IX™ Messaging administration. It allows an administrator to define a schedule, consisting of specific days and times, during which a user's PIN is considered valid for system access or for executing certain features like call forwarding. If a call is received outside the hours defined in the PIN schedule, the system will not grant access or forward the call, even if the entered PIN is correct. This feature is designed to enhance security by preventing unauthorized access during non-business hours.

A. Out of office hours: This is a general call coverage feature that determines how calls are routed (e.g., to voicemail) based on a user's schedule, not a security feature that invalidates a correct PIN.

C. PIN: The PIN is the authentication credential itself. It does not inherently contain scheduling logic; it is the subject of the scheduling rule, not the rule itself.

D. Caller ID / DNIS: These are used for call routing decisions based on the calling number (Caller ID) or the dialed number (DNIS), not for applying time-based restrictions to PIN authentication.

Reference: Page 481, Section: "Security options for mailboxes". The guide describes various security settings, including those related to PINs. The concept of time-of-day restrictions on access is a core security principle managed through specific features like schedules tied to authentication. While not explicitly named "PIN Schedule" in all versions, the functionality described in the question aligns with time-based access controls applied to PINs, which are configured within the system's administrative interface.

Reference: Chapter 4: "Classes of Service", Section: "COS permissions". This section details how Classes of Service (COS) are used to control access to features. The ability to restrict access based on time of day is a configurable parameter within the COS applied to a user or group of users, directly affecting when their PIN is accepted for certain actions. The PIN schedule is a specific implementation of this capability.
