What ensures the integrity of signaling in an Avaya Aura® Communication Manager environment?

The correct answer is A. Transport Layer Security (TLS). TLS (Transport Layer Security) ensures the integrity of signaling in Avaya Aura® Communication Manager by encrypting and authenticating the control messages (SIP, H.323) exchanged between endpoints and servers, preventing tampering or eavesdropping on call setup traffic. B…

Explanation

TLS (Transport Layer Security) ensures the integrity of signaling in Avaya Aura® Communication Manager by encrypting and authenticating the control messages (SIP, H.323) exchanged between endpoints and servers, preventing tampering or eavesdropping on call setup traffic.

B (MGCP) is a signaling protocol for controlling media gateways - it doesn't provide security/integrity itself.
C (SRTP) protects the media stream (the actual voice/audio packets), not the signaling channel.
D (IPSec) operates at the network layer and can secure IP traffic broadly, but it is not the Avaya-specific mechanism used to secure signaling in the Communication Manager architecture - TLS is the designated protocol for that layer.

Memory tip: Think "S for Signaling → TLS" vs. "S for Sound → SRTP." TLS locks the conversation setup, SRTP locks the conversation itself.
