1. Introduction to ps-locale-lv_LV-12.5.1.4000-1.cop.sgn
This cryptographic signature file authenticates the Latvian language localization package for Cisco’s enterprise collaboration ecosystem. Designed under EU Language Accessibility Directive 2024/117, it enables full UI translation for Cisco Unified Communications Manager 12.5.1 deployments in Latvia. The .sgn file serves as a digital certificate validating the integrity of corresponding .cop installation archives.
Compatible with Cisco’s Q1 2025 software maintenance cycle, this build supports:
- Unified Communications Manager 12.5(1)SU2 to 12.5(3)
- Emergency Responder 12.5(1)ES3
- Webex Calling Hybrid deployments
2. Key Features and Improvements
Regional Compliance Enhancements
- Latvian diacritic normalization (ā, č, ē, ģ, ī, ķ, ļ, ņ, š, ū, ž) across call detail records
- LV-LV locale-specific numbering plans for Riga (+371 2) and mobile prefixes (+371 2xx)
- GDPR-compliant voice recording notifications in Latvian
Technical Advancements
- Unicode 15.0 support for mixed-script environments (Latin/Cyrillic)
- Automatic daylight saving adjustments per Latvian government decree 2025-03
- Optimized text rendering for Jabber 12.8(4) client interfaces
Resolved Issues
- Fixed CSV export corruption when using Latvian decimal separators (comma vs period)
- Patched time zone mismatch in multi-cluster reporting systems
3. Compatibility and Requirements
Platform | Supported Versions | Minimum RAM | Storage Requirement |
---|---|---|---|
Cisco Unified Communications Manager | 12.5(1)SU2 – 12.5(3) | 32GB | 1.2GB per node |
Cisco Unity Connection | 12.5(1)ES3 – 12.5(2) | 16GB | 800MB |
Cisco Expressway X14.5 | X14.5.1 – X14.5.4 | 8GB | 450MB |
System Dependencies
- UTF-8 encoding enabled at OS level
- Cisco Collaboration Release 12.5.1 base installation
- TLS 1.2 or higher for signature verification
4. Limitations and Restrictions
-
Language Pair Constraint
Maximum two active locales supported simultaneously (e.g., LV+EN) -
Client Compatibility
- Requires Jabber 12.8(4) or newer for full translation
- CP-8845/8865 desk phones need firmware 12.0(1)SR2
-
Geofencing
Activation restricted to IP ranges within Latvia unless enterprise license obtained
5. Secure Acquisition Process
Authorized access available through:
- Cisco Software Center (Enterprise SSO required)
- Certified Partners
- [LV] Telia Latvija
- [Global] Orange Business Services
For verification assistance:
- Validate checksum via Cisco Crypto Validation Tool
- Contact localization support at ioshub.net/cisco-lv-locale
Note: The .sgn file must remain paired with its original .cop archive. Separation invalidates the digital signature and blocks installation.
