Introduction to cm-locale-it_CH-12.5.1.5000-1.cop.sgn

This cryptographic operations package enables native Italian (Switzerland) localization for Cisco Unified Communications Manager (CUCM) 12.5(1) deployments. Designed for Alpine region enterprise communications, it implements locale-specific formatting rules compliant with Swiss Federal Office of Communications (OFCOM) standards.

Released in Q4 2025 as part of Cisco’s European Language Compliance Initiative, this signed COP file (build 5000-1) resolves localization vulnerabilities identified in CVE-2025-5571 related to multilingual text rendering. Compatible with Cisco UCS C-Series servers running CUCM 12.5(1) SU3+, it supports hybrid deployments integrating Webex Contact Center and Jabber clients in multilingual Swiss environments.
