​​Introduction to CUBAC_All_CUCMs_V1.1.2.23_07.08.07.zip​​

This bulk administration package provides centralized configuration management for Cisco Unified Communications Manager (CUCM) 12.5(1)SU2 clusters and later versions. Released under Cisco’s Collaborative Maintenance Program on August 7, 2023, the ZIP archive contains optimized templates for mass device provisioning, user account synchronization, and security policy enforcement across multi-cluster environments.

The update specifically addresses enterprise-scale deployments requiring cross-cluster consistency in directory number assignments, device mobility configurations, and extension mobility profiles. Compatible with both on-premises CUCM installations and Cisco-hosted Collaboration Flex Plan implementations, it supports automated batch operations through enhanced CSV/XML schema validation.
