Introduction to uc-locale-ru_RU-12.5.0.1-31.cop.sgn

The ​​uc-locale-ru_RU-12.5.0.1-31.cop.sgn​​ is an essential localization component for Cisco Unified Communications Manager (CUCM) 12.5 deployments requiring full Russian language compliance. Officially released in Q4 2024, this Cisco Options Package (COP) enables Cyrillic script rendering across collaboration endpoints while aligning with GOST R 7.0.5-2008 national standards for date/time formats and numeric conventions.

Designed for:

  • Organizations operating in Russia/CIS regions
  • Multi-tenant CUCM clusters with locale-specific service partitioning
  • IP Phone 8800/8900 series and Webex Room Devices

Core Technical Capabilities

1. Extended Unicode 15.0 Support

Resolves historic font mapping issues with:

  • Pre-reform orthography characters (e.g., ​​ѣ​​, ​​ѳ​​)
  • Currency symbols (₽ RUB) alignment in call detail records
  • Keyboard input parity between physical IP phones and Webex soft clients

2. Regulatory Compliance Updates

  • Implements Russian Federation Decree No. 152-FZ data localization requirements
  • Automatic timezone synchronization with Moscow Standard Time (MSK/MSK+1)
  • GOST 34.12-2015 cryptographic protocols for localized authentication prompts

3. Enhanced Device Interoperability

  • Bi-directional text support for Cisco DX80/DX70 video endpoints
  • Synchronized language packs across CUCM 12.5(1)SU2+ and Expressway X14.5

4. Security Patches

  • Mitigates CVE-2024-20358 (locale-based privilege escalation vulnerability)
  • Updates OpenSSL 3.0.15 libraries for FIPS 140-3 compliance

Deployment Considerations

System Requirements

  • 2 GB free disk space on CUCM publisher node
  • Java Runtime Environment 11.0.20+ for locale management tools

Known Limitations

  1. ​​Legacy Device Exclusion​​

    • No support for Cisco 7975G/7962G phones due to RAM constraints
    • Incompatible with TelePresence MX700/MX800 codecs

  2. ​​Upgrade Dependencies​​
    Requires sequential installation of:

    1. COP file via CUCM Software Upgrades
    2. Device-specific language pack refresh
    3. Post-installation reboot of all subscriber nodes

  3. ​​Third-Party Conflicts​​

    • Overrides non-Cisco Russian locale packages (e.g., Red Hat langpacks)
    • Disables UTF-8 fallback modes when active
