Avaya Equinox is a unified communications client for mobile and desktop devices, offering features like softphone calling, IM, and presence. To use Equinox on a mobile device with IP Office, a user requires the "Power User" profile (Option B). This profile includes licenses for advanced mobility features, such as softphone functionality and integration with Equinox, allowing seamless access to IP Office features remotely. Option A (Teleworker) is for remote deskphone users, Option C (Basic) provides minimal features, and Option D (Remote Worker) is specific to certain remote configurations, none of which fully support Equinox without additional licensing.

The Avaya IP Office Manager is a critical administrative tool used to configure and manage IP Office systems, including the Server Edition. The Server Edition is a scalable solution designed for larger deployments, allowing multiple IP Office servers (Primary, Secondary, and Expansion systems) to work together as a single system. Option B, "Manager shows the status of all servers on one screen," is true because, in Server Edition deployments, the IP Office Manager provides a consolidated view of the network, displaying the status of all connected servers (e.g., Primary Server, Secondary Server, and Expansion Systems) in a single interface. This feature simplifies monitoring and management across distributed systems. Option A is incorrect because, while web-based management exists (via Web Manager), the traditional Manager application is a standalone Windows-based tool, not fully ported to Web Management. Option C is incorrect as the Voicemail Pro Client is a separate application, not bundled within Manager. Option D is also incorrect because Manager is typically installed on a separate PC, not directly on the server itself, though it communicates with the server for configuration.

The default port for SIP signaling in IP Office, as per industry standards, is 5060 (Option A). This applies to SIP trunks and endpoints unless customized. Option B (1720) is for H.323, Option C (8080) is for web services, and Option D (443) is for HTTPS. References: Avaya IP Office SIP Configuration Guide.

Call Pickup (Option A) enables a user to answer a call ringing on another extension using a feature code (e.g., *30). Option B redirects calls, Option C distributes calls, and Option D links to external numbers—none perform pickup. References: Avaya IP Office Feature Code Guide.

The TCM8 card (Option A) supports Avaya 9500 series digital phones on the IP500 V2 by providing digital station ports. Option B (Phone 8) is for analog phones, Option C is for trunks, and Option D is for voicemail—not digital phones. References: Avaya IP Office IP500 V2 Installation Manual.

Do Not Disturb (DND) (Option B) sends calls directly to voicemail when enabled, bypassing ringing. Option A redirects to another number, Option C retrieves voicemail, and Option D is a synonym for forwarding—not immediate voicemail. References: Avaya IP Office User Feature Guide.

The Avaya IP Office Server Edition is designed for scalability, supporting a large number of users across multiple servers. The maximum capacity is 2500 users (Option D), achieved in a fully expanded deployment with a Primary Server, Secondary Server, and multiple Expansion Systems (up to 148 additional systems). This capacity includes all types of users (e.g., Basic, Power, Teleworker) and requires sufficient licensing and hardware resources (e.g., virtualized or dedicated servers). Options A (500), B (1000), and C (2000) represent lower tiers or partial configurations but do not reflect the full potential of Server Edition.
