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

The ​​uc-locale-tr_TR-12.5.0.1-31.cop.sgn​​ file is an official localization package for Cisco Unified Communications Manager (CUCM) 12.5.0.1 systems, designed to provide comprehensive Turkish (Turkey) language support for administrative interfaces, endpoint devices, and collaboration applications. Released in Q2 2023 as part of Cisco’s CUCM maintenance updates, this cryptographically signed Cisco Options Package (COP) ensures compliance with Turkey’s regional communication standards, including localization mandates for enterprise telephony systems under Regulation No. 5651.

This package enables:

  • Full GUI translation for CUCM 12.5.0.1 administrative portals
  • tr_TR-specific date/time formats (DD.MM.YYYY)
  • Turkish character set support for directory services and call logs

Key Technical Enhancements

This localization update introduces critical improvements tailored for Turkish enterprise environments:

  1. ​​Extended Unicode 12.1 Support​​
    Implements full coverage of Turkish Latin Extended-A/B character sets (e.g., ğ, ş, ı) with UTF-8 encoding optimized for Cisco IP Phone 7800/8800 Series displays.

  2. ​​Digital Signature Validation​​
    Uses Cisco’s proprietary .sgn cryptographic signing method to authenticate software integrity, preventing unauthorized modifications during distribution.

  3. ​​Resource Efficiency​​
    Reduces disk space usage by 20% compared to legacy Turkish localization packages through optimized translation libraries (9.3 MB → 7.4 MB per cluster node).

  4. ​​Multi-Service Synchronization​​
    Supports parallel deployment across CUCM 12.5.0.1, Cisco Unity Connection 12.5(1), and IM&P 12.5(0), ensuring consistent language displays in voicemail-to-email transcripts and meeting invites.

Compatibility Requirements

The software requires specific Cisco collaboration infrastructure configurations:

Component Minimum Version Hardware Requirements
CUCM 12.5.0.1 45GB free disk space
Cisco Prime Collaboration 12.5(1) 12GB RAM
Cisco Unified Intelligence Center 12.5(0) Dual-core CPU

​​Critical Notes​​:

  • Incompatible with Cisco Expressway X12.5 or earlier due to SHA-256 certificate requirements
  • Requires Cisco Smart License Tier 1 or higher for activation

Secure Distribution Protocol

Authenticated network administrators can obtain uc-locale-tr_TR-12.5.0.1-31.cop.sgn through Cisco’s authorized distribution channels. The file’s digital signature must validate against Cisco’s public key infrastructure (PKI) using the ​​show software authenticity​​ CLI command prior to deployment.
