Introduction to aa_04-11-04-Msk.aef

This signed automation template enables seamless integration between Cisco Unified Communications Manager (CUCM) 14.x and Apache Kafka clusters in AWS/MSK environments. Designed for real-time event streaming in hybrid UC deployments, it automates Kafka topic provisioning, security policy synchronization, and telemetry data pipeline configurations.

The “.aef” extension denotes Cisco’s Automated Enterprise Framework format, validated through CUCM’s cryptographic verification system. Released under Cisco’s Q1 2025 Unified CM 14.2(1) SU2 update, it addresses GDPR/CCPA compliance requirements for distributed contact center logging and AI-driven call analytics.
