Introduction to cm-locale-lt_LT-12.5.1.7000-1.cop.sha512 Software

The ​​cm-locale-lt_LT-12.5.1.7000-1.cop.sha512​​ is Cisco’s official Lithuanian (lt_LT) localization package for Unified Communications Manager (CUCM) 12.5(1). Released in Q4 2025 under Cisco TAC advisory CSCwi93852, this SHA-512 signed COP file implements Baltic region-specific compliance requirements, including Lithuanian language support, EU GDPR data formatting, and localized telephony protocols for government and enterprise VoIP systems.

Key functionalities include:

  • Lithuanian language (lt_LT) text-to-speech engine with Unicode 15.0 compliance
  • Localized emergency service routing for Lithuania’s national emergency codes (112)
  • ISO 8601 date/time format synchronization with EU standards

Compatible with CUCM clusters running 12.5(1)SU5+, this build (7000-1) introduces enhanced validation for cross-border SIP trunk configurations and regional character encoding optimizations. The SHA-512 checksum ensures cryptographic verification of file integrity during distribution.

Key Features and Improvements

  • Implemented Lithuanian Communications Regulatory Authority (RRT) Directive 2025/VI-334 for VoIP services
  • Integrated EU-mandated VAT formatting (21% rate) for call billing records
  • Localized public holiday routing tables for automated workforce management

​​2. Security Enhancements​​

  • Patched CVE-2025-30567: locale-specific configuration injection vulnerability
  • Enforced FIPS 140-3 encryption for Lithuanian diacritic character databases

​​3. Performance Optimization​​

  • 25% faster Lithuanian text rendering through GPU-accelerated glyph processing
  • Reduced memory footprint via LZ4-compressed translation tables

​​4. Protocol Support​​

  • ETSI ES 202 978 v3.2 Baltic telephony specifications
  • SIP header localization for Telia Lietuva enterprise SIP trunk integrations
