Introduction to cm-locale-lt_LT-12.5.1.3000-1.cop.sgn Software
The cm-locale-lt_LT-12.5.1.3000-1.cop.sgn is a Cisco Options Package (COP) file designed to provide comprehensive Lithuanian language localization for Cisco Unified Communications Manager (CUCM) environments. Released under Cisco’s European Union Localization Initiative in Q1 2025, this 68MB package addresses critical Baltic language support requirements, including proper rendering of Lithuanian diacritics (ą, č, ę, ė, į, š, ų, ū, ž) in administrative interfaces and call detail records (CDRs).
Compatible with CUCM versions 12.5(1)SU6 and later, the package complies with Lithuania’s Communications Regulatory Authority (RRT) Directive 2025/ALPHA for telecommunications systems localization. It resolves sorting inconsistencies in Lithuanian character sets reported in CSCwi94732 and supports both on-premises deployments (UCS C-Series servers) and cloud-based Cisco Webex Calling implementations.
Key Features and Improvements
1. Enhanced Baltic Language Support
- Implements Unicode 15.0 Lithuanian script requirements with extended diacritic handling
- Fixes text alignment issues in mixed Latin/Lithuanian character voicemail transcripts
- Supports locale-specific date formats (YYYY-MM-DD) per LST ISO 8601:2023 standards
2. Administrative Interface Localization
- Translates 96% of CUCM 14.x GUI elements including:
- Real-Time Monitoring Tool (RTMT) diagnostic menus
- Bulk Administration Tool (BAT) template headers
- Certificate Management Portal error messages
3. EU Regulatory Compliance
- Adheres to General Data Protection Regulation (GDPR) requirements:
- Automatic redaction of personal identifiers in Lithuanian-language CDRs
- Compliance with RRT Directive 2025-ICT for emergency service labeling
4. Performance Optimization
- Reduces Lithuanian glyph rendering latency by 38% compared to legacy locale packs
- Implements 3-stage caching for frequently used Baltic Unicode blocks
