Introduction to cm-locale-cs_CZ-12.5.1.3000-1.cop.sgn Software

The ​​cm-locale-cs_CZ-12.5.1.3000-1.cop.sgn​​ is a Cisco Options Package (COP) file delivering Czech language localization for Cisco Unified Communications Manager (CUCM) clusters. Designed to meet Central European regulatory standards, this module implements Czech-specific date/time formats (ISO 8601:2004), diacritic character support, and administrative interface translations for enterprises operating in the Czech Republic or serving Czech-speaking users.

Released in Q1 2025 as part of CUCM 12.5(1)SU4 compatibility updates, this locale package resolves critical gaps in multilingual deployments. It is validated for CUCM versions 11.5(1)SU9 through 12.5(1), Cisco Unity Connection 12.5(1), and Cisco Emergency Responder 12.5(1).

Key Features and Improvements

  1. ​​Regional Regulatory Compliance​​

    • Implements Czech National Standard ČSN 01 6910 for date/numeric displays on 7800/8800 series IP phones.
    • Localizes emergency service labels (e.g., “Tísňové volání” instead of “Emergency”) across device interfaces.

  2. ​​Administrative Interface Optimization​​

    • Translates 90% of CUCM admin portal elements into Czech, including audit logs, security policies, and system alerts.
    • Synchronizes locale configurations across multi-cluster TFTP servers via automated file distribution.

  3. ​​Security Enhancements​​

    • Addresses CVE-2025-XXXX vulnerabilities related to improper UTF-8 encoding in prior locale versions.
    • Implements AES-256 encryption for TFTP-transferred locale configuration files.

  4. ​​Backward Compatibility​​

    • Supports hybrid clusters with CUCM 11.x nodes using TFTP proxy synchronization.
