Introduction to ps-locale-ko_KR-12.5.1.8001-1.cop.sha512 Software

This localization package provides comprehensive Korean (ko_KR) language support for Cisco’s Unified Communications Manager 12.5.1 ecosystem, translating 2,800+ system interfaces including voicemail prompts, administrator portals, and device error messages. Designed for enterprises operating in South Korea, it complies with the country’s 2025 Telecommunications Standardization Act by implementing KS X 1005:2024 character encoding and locale-specific number/date formats.

The 12.5.1.8001 version introduces SHA512 cryptographic verification to replace deprecated MD5 checksums, aligning with Cisco’s Enhanced Secure Development Lifecycle (eSDL) framework. Compatible with CUCM clusters, Webex Calling hybrid deployments, and Cisco Emergency Responder 12.5.1 SU3+, this release became generally available on March 15, 2025 per Cisco’s quarterly maintenance schedule.
