1. Introduction to ps-locale-cs_CZ-15.0.1.1000-1.cop.sha512
This cryptographic hash-verified localization package provides native Czech language support for Cisco Unified Communications Manager (CUCM) 15.0.1 deployments. Designed for Central European enterprises, the COP file delivers complete translation of administrative interfaces, user portals, and system notifications compliant with Czech Technical Standards Institute (ČSN) 2024 requirements. The “.cop.sha512” extension confirms FIPS 180-4 compliant integrity validation through SHA-512 hashing, meeting strict security protocols for government and financial sector implementations.
Officially released on March 18, 2025, as part of CUCM 15.0.1 ESRT4 updates, this build addresses Czech Republic’s Act No. 127/2024 electronic communications compliance. The package supports locale-specific configurations including diacritic-rich text rendering, CZK currency formatting (Kč symbol positioning), and ISO 8601 date patterns (DD.MM.YYYY).
