Network engineers specializing in enterprise unified communications must demonstrate mastery in designing complex Avaya Aura core infrastructure, specifically focusing on Session Manager, Communication Manager, and System Manager deployments. Candidates implement SIP-based call routing, survivability protocols, and load balancing within distributed network topologies. The certification validates proficiency in QoS configuration, bandwidth provisioning, and security hardening for multi-vendor VoIP environments. Experts must architect seamless integration between Avaya gateways, media servers, and PSTN interfaces while addressing codec selection and H.323 to SIP interworking requirements. Mastery requires granular understanding of signaling flows, endpoint registration logic, and effective traffic engineering across integrated IP-based communication architectures.
