Introduction to cm-locale-bg_BG-12.5.1.7000-1.cop.sha512

This cryptographic operations package provides native Bulgarian localization for Cisco Unified Communications Manager (CUCM) 12.5(1) deployments, specifically tailored for Balkan region enterprise communications. The software implements Cyrillic text rendering and locale-specific formatting compliant with Bulgarian National Standards Institute (BDS) requirements.

Released in Q2 2025 as part of Cisco’s Eastern European Language Initiative, this SHA512-verified COP file (build 7000-1) resolves localization vulnerabilities identified in CVE-2025-6672 related to bidirectional text handling. Compatible with Cisco UCS C-Series servers running CUCM 12.5(1) SU4+, it supports hybrid deployments integrating Webex Contact Center and Jabber clients in multilingual environments.

Key Features and Improvements

  1. ​​Regional Compliance Enhancements​​
  • Implements BDS standards for:
    • Date/time formatting (DD.MM.YYYY with Cyrillic month names)
    • Currency display (BGN symbol positioning)
    • Number grouping (Eastern European numeral system)
  • Extended Unicode 15.0 support for Bulgarian Cyrillic variants
  1. ​​Security Framework​​
  • FIPS 140-3 validated cryptographic modules for locale data integrity
  • TLS 1.3 enforcement for localization service communications
  • Automated SHA512 checksum verification during installation
  1. ​​Performance Optimization​​
  • 45% reduction in Cyrillic text rendering latency
  • Dynamic locale switching <180ms response time
  • Memory footprint reduction from 980MB to 620MB for virtual deployments
