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

This localization package delivers comprehensive Czech language support for Cisco Unified Communications Manager (CUCM) v12.5 systems, aligning with Czech Republic’s Language Act (No. 101/2025 Coll.) requirements for public sector software. Released on October 17, 2025 as part of Cisco’s EMEA localization roadmap, the COP file updates 1,563 administrative interface elements and implements ČSN 97 6030 standards for diacritic handling in telephony systems.

Compatible with CUCM clusters running on UCS C-Series M7 servers (C220/C240) and VMware ESXi 8.0 U3+ virtual environments. The package preserves backward compatibility with existing H.323/SIP trunk configurations while upgrading locale-specific voice prompt libraries.
