Explanation

Avaya Aura® Communication Manager uses SIP (Session Initiation Protocol) to communicate with Avaya Aura® Media Server because SIP is the signaling protocol that controls media sessions - it handles the setup, management, and teardown of calls between the two systems.

Why the distractors are wrong:

• H.323 (B) is an older VoIP signaling protocol that Communication Manager does support for some endpoints, but it is not used for CM-to-Media Server communication.
• SCCP (C) (Skinny Client Control Protocol) is a Cisco proprietary protocol for IP phones - it has no role in Avaya's architecture.
• RTP (D) (Real-time Transport Protocol) carries the actual audio/video media stream, not the signaling between CM and Media Server - it's the "what," not the "how they talk."

Memory tip: Think "SIP = Signaling between Internal Platforms." In Avaya Aura's architecture, SIP is the universal signaling glue between core components like CM and Media Server, while RTP handles the actual voice data separately.
