Which three features does Avaya IX™ Messaging offer? (Choose

Avaya IX™ Messaging (also known as Avaya Aura® Messaging) is a comprehensive unified messaging solution. Its architecture is built upon a hardened Linux operating system (A), typically deployed as a virtual appliance. A core design principle is its flexible integration capability, supporting both traditional on-premise PBX systems (like Avaya Aura® and IP Office) and modern Cloud services, particularly for email integration with platforms like Microsoft 365 and Google G Suite (B). Functionally, it delivers a rich set of unified communication features, including voicemail-to-email, automated attendants, and advanced optional services such as integrated Fax, Speech (text-to-speech), and Transcription (speech-to-text) services (D).

C. H.323 integration: Avaya IX™ Messaging integrates into the Avaya Aura® core primarily using the Session Initiation Protocol (SIP) via Session Manager, not the H.323 protocol.

E. JITC Security and Encryption: While Avaya Aura® Messaging is part of the Avaya solution suite that has achieved JITC certification, this represents a specific security standard for government use, not a universal core feature compared to its OS, integration model, and primary services.
