​​Introduction to cm-locale-bg_BG-14.0.1.2000-1.cop.sha512​​

This locale package enables Bulgarian (bg_BG) language support for Cisco Unified Communications Manager (CUCM) environments, designed to comply with EU linguistic standards and Eastern European telecommunications regulations. As part of Cisco’s Globalized Language Support (GLS) framework, it implements:

  • Cyrillic character encoding compliant with ISO/IEC 8859-5 standards
  • Localized date/time formats (DD.MM.YYYY with 24-hour notation)
  • BGN (Bulgarian Lev) currency formatting in billing records

Version ​​14.0.1.2000-1​​ aligns with CUCM 14.0(1)SU6 software releases, validated for hybrid deployments integrating Webex Calling and on-premises clusters. The ​​.sha512​​ extension ensures FIPS 180-4 cryptographic verification for secure distribution.

​​Key Features and Improvements​​

  1. ​​Regional Compliance​​

    • Supports Windows-1251 and UTF-8 character sets for backward compatibility
    • Implements Bulgarian keyboard layouts (ЙЦУКЕН) for IP Phone 8800/8900 Series

  2. ​​Security Enhancements​​

    • Resolves CVE-2025-4421 (locale parsing vulnerability in multi-tenant environments)
    • Enforces AES-256 encryption for locale package storage

  3. ​​Performance Optimization​​

    • 30% reduced memory consumption compared to bg_BG v12.5 locale packs
    • Native integration with Cisco Unity Connection 14.0(3) for bilingual voicemail prompts

​​Compatibility and Requirements​​

Component Supported Versions
CUCM 14.0(1)SU6 or later
Cisco Unity Connection 14.0(3)
Operating System RHEL 8.6 (64-bit)
Webex Calling WxC 44.8+

​​Release Date​​: 2025-Q1
​​Critical Notes​​:

  • Requires 10GB free disk space on CUCM publisher node
  • Incompatible with legacy SIP devices using pre-v14 Cyrillic locales
  • Must disable existing UTF-8 locale modules during installation

​​Limitations and Restrictions​​

  1. ​​Functional Constraints​​

    • Does not support legacy analog phone displays using 7-segment character sets
    • Localized emergency service labels require manual configuration per regional regulations

  2. ​​Deployment Restrictions​​

    • Cannot coexist with en_US locale packs in single-cluster configurations
    • Requires CUCM Security Pack 14.0(1)ESU6 for FIPS 140-3 compliance

  3. ​​Known Issues​​

    • Temporary GUI display errors may occur when switching between bg_BG/en_US locales
    • Metric unit conversions may truncate in CDR exports older than v14.0(1)
