An Avaya Aura® Messaging (AAM) consolidated server provides administrators with the ability to manage all aspects of the messaging system. The administrative interface is logically separated into different functions. Core messaging administration includes managing organizational structures like Company for multi-tenancy, configuring individual user Mailbox Settings (e.g., passwords, greetings, notifications), and defining sets of permissions through Feature Groups. These settings directly control the user experience and available features within the messaging application itself.

B. SIP Settings: This is a system-level server configuration for network integration with Session Manager, not a logical messaging object setting like a mailbox or feature group.

E. PBX Settings: These are configured on the PBX (e.g., Avaya Aura® Communication Manager) itself. The AAM server integrates with the PBX but does not administer its settings.

Reference for A, C, D: The Table of Contents explicitly groups these functions under "Part 2: Messaging administration". Chapter 5 is "Administering companies," Chapter 6 is "Administering mailboxes," and Chapter 7 is "Administering feature groups." This shows they are primary, related administrative domains.

Reference for B: The same document places SIP configuration under a separate section, "Part 3: Server administration," in Chapter 15, "Administering SIP configuration," distinguishing it from core messaging object administration.

Reference for E: Section "Avaya Aura® Messaging integration with Communication Manager," page 28, describes the integration points. It details how AAM uses information from the PBX but clarifies that administration of the PBX (stations, trunk groups) is performed on the Communication Manager platform, not from the AAM server.
