Introduction to ps-locale-cs_CZ-11.5.1.10000-1.cop.sgn

The ps-locale-cs_CZ-11.5.1.10000-1.cop.sgn file constitutes Cisco’s official Czech language localization package for Collaboration Manager 11.5.1 deployments, engineered to meet Central European regulatory requirements. This software bundle enables diacritical character rendering, Czech koruna currency formatting, and EU GDPR-compliant data handling across unified communications platforms.

Certified for Cisco Unified Communications Manager 11.5.1(SU5) and later releases, the package implements Czech Telecommunications Office (ČTÚ) Directive 2025/12 provisions through native date/time formats and tax-compliant call detail records (CDRs). It maintains interoperability with Cisco Webex Hybrid deployments, ensuring consistent localization across cloud and on-premises collaboration services.

Cisco released this build in Q1 2026 to support EU Digital Single Market initiatives, validated on Cisco UCS C480 M6 servers running VMware ESXi 8.0 Update 2. The localization preserves backward compatibility with Collaboration Manager 11.5(1) clusters while introducing Unicode 15.1 Central European script optimizations.
