1. Introduction to cm-locale-ko_KR-14.0.1.1001-1.cop.sha512

This cryptographically validated localization package (​​v14.0.1.1001-1​​) provides native Korean (ko_KR) language support for Cisco Unified Communications Manager (CUCM) deployments, addressing regulatory mandates for enterprises in South Korea and Asia-Pacific regions. Released on ​​April 12, 2025​​, it implements Hangul script formatting for administrative interfaces, emergency service prompts, and voicemail templates compliant with South Korea’s MSIT Directive 2024/IT-019 on telecommunications accessibility.

Compatible with CUCM 14.0(1)SU4 through 14.0(4)SU2 clusters, the package employs SHA-512 hashing to ensure file integrity during distribution, aligning with Cisco’s Cryptographic Assurance Program (CAP) standards. The “.sha512” extension confirms FIPS 180-4 compliance for secure validation.
