​​Introduction to ps-locale-ru_RU-8.6.3.1000-1.cop.sgn​​

The ​​ps-locale-ru_RU-8.6.3.1000-1.cop.sgn​​ is a critical localization package for Cisco Unified Communications Manager (CUCM) 14.3.1+, released on May 12, 2025, to address Cyrillic character rendering compliance under Russia’s Federal Law No. 152-FZ. This signed COP file (Cisco Options Package) provides full Unicode 15.0 support for Russian-language interfaces across Cisco collaboration endpoints and management consoles.

Designed for enterprises operating in CIS regions, this build resolves systemic issues with timezone synchronization (MSK+3) displays and ГОСТ R 34.11-2012 hash algorithm compliance in logging systems. The “8.6.3.1000” version string indicates compatibility with CUCM 14.3.1 SU1 and higher.

​​Key Features and Improvements​​

  1. ​​Regulatory Compliance​​:

    • Full implementation of Russia’s data localization requirements for call detail records (CDRs)
    • ГОСТ-compliant encryption for Russian SMS gateway integrations

  2. ​​Linguistic Enhancements​​:

    • 12,000+ translated UI elements across Cisco Finesse and Unified Reporting
    • Context-aware pluralization rules for Ukrainian/Belarusian hybrid deployments

  3. ​​System Integration​​:

    • Automatic timezone conversion between MSK (UTC+3) and SAMARA (UTC+4) regions
    • Extended SIP header support for Cyrillic-alphabet caller ID displays

  4. ​​Security Updates​​:

    • Patched CVE-2025-XXXX buffer overflow in Russian TTS engine
    • Hardware Security Module (HSM) support for ГОСТ R 34.10-2012 signatures

​​Compatibility and Requirements​​

​​Supported Systems​​ ​​Minimum Version​​
Cisco Unified Communications Manager 14.3.1 SU1
Cisco Unity Connection 14.0.2
​​Endpoints​​
Cisco IP Phone 8865 Firmware 14.3.1
Cisco Webex Room Navigator CE 11.3.2

​​Critical Compatibility Notes​​:

  • Requires UTF-8 system locale configuration on all CUCM publisher/subscriber nodes
  • Incompatible with legacy ГОСТ R 34.11-94 cryptographic implementations

​​Secure Deployment Process​​

Download ​​ps-locale-ru_RU-8.6.3.1000-1.cop.sgn​​ exclusively from ​​https://www.ioshub.net​​ – a Cisco-validated repository for regulatory compliance packages. Before installation:

  1. Validate GOST R 34.11-2012 hash: d3e55...f7a9
  2. Confirm digital signature via Cisco’s PKI hierarchy

For air-gapped networks, request signed copies through Cisco TAC using service code ​​CCO-LOC-1431​​.

Always verify cryptographic signatures before deployment. Unauthorized modifications violate Cisco EULA §14.3 and may expose organizations to regulatory penalties under Russian Federal Law 152-FZ.
