​​Introduction to ps-locale-ko_KR-14.0.1.3000-1.cop.sha512​​

This SHA512-validated locale package provides Korean (South Korea) language support for Cisco Unified Communications Manager (CUCM) 14.0(1), designed to meet South Korea’s Telecommunications Business Act (2024 Amendment) and EU GDPR cross-border data localization requirements. Released on ​​August 25, 2025​​, it includes Hangul script rendering optimizations, E.164 numbering plan adaptations for South Korea’s +82 country code, and localized administrative interfaces for IP phone displays.

The SHA512 cryptographic hash embedded in the filename ensures FIPS 180-4 compliance for secure enterprise deployments. Compatible with Cisco IP Phone 8800/8900 Series and Webex Room Kit Pro, it supports dual-byte UTF-8 encoding for Korean characters like “ㄱ”, “ㅏ”, and compound syllables (e.g., “가”).

​​Key Technical Enhancements​​

  1. ​​Regional Regulatory Compliance​​

    • Implements South Korea’s KCC Regulation 2025-08 for call detail records (CDRs), including mandatory 12-digit numbering for Seoul (02) and Busan (051) area codes.
    • Supports vertical text rendering modes for legacy systems requiring Hangul script alignment.

  2. ​​Security Validation​​

    • SHA512 checksum verification uses 1024-bit block processing and 512-bit message digests to prevent tampering during distribution.
    • Aligns with ISO/IEC 10118-3 standards for government-grade encryption.

  3. ​​Performance Optimization​​

    • Reduces Hangul text processing latency by 24% compared to CUCM 12.5(1) locale packs.
    • Optimizes memory allocation for multi-language interfaces (max. 2.7GB RAM utilization).

​​Compatibility Requirements​​

​​Component​​ ​​Supported Versions​​
CUCM Base System 14.0(1)SU8 or later
Cisco IP Phones 8800/8900 Series, Webex Room Kit Pro
Operating Systems Cisco OS 2025.7+, RHEL 9.7

​​Limitations and Restrictions​​

  1. ​​Regional Format Constraints​​

    • Does not support legacy Seoul area code “02” formatting without +82 prefix.

  2. ​​Third-Party Integration​​

    • Limited compatibility with non-Cisco SIP devices using RFC 3261 extensions.
