Introduction to cm-locale-cs_CZ-12.5.1.4000-1.cop.sgn

This digitally signed COP file provides official Czech localization for Cisco Unified Communications Manager (CUCM) 12.5.1 systems, designed to meet Czech Republic telecommunications regulations and linguistic requirements. Released under Cisco’s Q4 2024 globalization initiative, it implements CZK currency formatting (Kč), Central European Time (CET) synchronization, and emergency service mapping compliant with Czech Telecommunication Office (ČTÚ) standards.

Compatible with CUCM clusters running 12.5(1)SU2 or later, the package modifies 16 core services including Cisco Unified Reporting and Certificate Authority Proxy Function (CAPF). The “cs_CZ” locale code follows IETF BCP 47 standards, requiring UTF-8 character encoding and integration with Cisco Security Agent 12.5.1.6000+ for cryptographic validation.
