1. Introduction to ciscocm.CTIManager_v1.12.k3.cop.sgn Software

The ciscocm.CTIManager_v1.12.k3.cop.sgn is a critical security update package for Cisco Unified Communications Manager (CUCM) CTI Manager services, designed to address CVE-2024-32560 vulnerabilities while enhancing TLS 1.3 encryption compliance. Released in Q2 2025 under Cisco’s Zero Trust Architecture Initiative, this digitally signed COP file implements NIST SP 800-193 standards for persistent firmware protection and FIPS 140-3 validated cryptographic operations.

Compatible with CUCM 12.5(1) SU2 clusters, the update introduces automated certificate rotation for CTI connections and enforces CALEA-compliant session auditing. It maintains interoperability with Cisco Jabber 14.5+ clients and Webex App 45.2+ endpoints while supporting UCS C-Series M7 servers with hardware-rooted trust verification.
