Introduction to ciscocm.postUpgradeCheck-00041.cop.sha512

This SHA512-verified Cisco Options Package (COP) provides automated system validation for Cisco Unified Communications Manager (CUCM) 15.5SU2 clusters after major software upgrades. Designed to address configuration drift risks in enterprise collaboration environments, it implements 19 critical health checks aligned with NIST SP 800-53 rev5 security controls and ITU-T X.1305 telecommunication standards.

The “postUpgradeCheck-00041” identifier confirms resolution of CVE-2023-20048-related configuration inconsistencies reported in CUCM 15.0 environments. This utility performs cryptographic verification of service certificates while mapping SIP/H.323 protocol dependencies across distributed media processing nodes.
