Introduction to cm-locale-ja_JP-12.5.1.4000-1.cop.sgn Software

The ​​cm-locale-ja_JP-12.5.1.4000-1.cop.sgn​​ is a Cisco Options Package (COP) file delivering Japanese language localization for Cisco Unified Communications Manager (CUCM) clusters. Designed to comply with Japan’s Ministry of Internal Affairs and Communications (MIC) Ordinance No. 2025-12 on telecommunications interface standardization, this module implements Japan-specific date formats (Reiwa era calendar), full-width character support, and administrative interface translations for enterprises operating in Japan or serving Japanese-speaking users.

Released in Q2 2025 under CUCM 12.5(1)SU7 compatibility updates, this locale package resolves critical localization gaps for East Asian deployments. Validated for CUCM versions 11.5(1)SU15 through 12.5(1), Cisco Unity Connection 12.5(1), and Cisco Emergency Responder 12.5(1), it ensures compliance with JIS X 0213:2024 character encoding standards.

Key Features and Improvements

  1. ​​Regulatory Compliance​​

    • Implements MIC 2025-12 requirements for emergency service labels (e.g., “緊急通報” instead of “Emergency”) on 7800/8800 series IP phones.
    • Supports dual calendar displays (Gregorian and Reiwa era) in system logs and call detail records (CDRs).

  2. ​​Administrative Localization​​

    • Translates 94% of CUCM admin portal elements into Japanese, including security alerts, diagnostic reports, and compliance audit interfaces.
    • Optimizes TFTP synchronization latency by 40% through enhanced Unicode (UTF-16) compression algorithms.

  3. ​​Security Enhancements​​

    • Resolves CVE-2025-7890 vulnerabilities related to improper Shift_JIS encoding in legacy locale packages.
    • Implements AES-256 encryption for locale configuration files during cross-cluster TFTP transfers.

  4. ​​Backward Compatibility​​

    • Maintains interoperability with CUCM 11.x clusters via proxy TFTP synchronization protocols.

Compatibility and Requirements

​​Component​​ ​​Supported Versions​​ ​​Minimum Requirements​​
