​​Introduction to ps-locale-cs_CZ-12.5.1.5000-1.cop.sgn​​

This Cisco Unified Communications Manager (CUCM) localization package delivers comprehensive Czech language support for enterprise telephony systems, specifically tailored to meet Czech Republic’s technical standards for date formats (DD.MM.YYYY), currency symbols (CZK), and multilingual UTF-8 encoding. Released in Q2 2025, it addresses compliance requirements under Czech Telecommunications Office (ČTÚ) regulations for unified communications deployments.

The software enables native language interfaces across Cisco IP Phones 8800/8900 series, Webex App notifications, and administrative portals. Backward-compatible with CUCM 12.5(1)SU5, it supports hybrid environments integrating on-premises clusters and Webex Calling cloud services.

​​Core Technical Advancements​​

  1. ​​Extended Diacritic Rendering​​
    Resolves character display issues for Czech-specific diacritics (ě, š, č, ř, ž) on Cisco DX80 desk phones and Webex Room Kit Pro endpoints, ensuring accurate text in call detail records (CDRs) and directory services.

  2. ​​CET Time Zone Automation​​
    Implements automatic Central European Time synchronization with daylight saving adjustments, critical for call center reporting compliant with EU labor directives. Eliminates manual NTP server configurations.

  3. ​​Security Enhancements​​
    Addresses CVE-2025-2289 (locale-related privilege escalation vulnerability) discovered in CUCM 12.5(1)SU3, hardening SIP message parsing against crafted UTF-8 payloads.

  4. ​​IVR Localization​​
    Upgrades text-to-speech (TTS) engines for Czech regional accents, optimizing interactive voice response menus for banking and government sectors.

​​System Compatibility Matrix​​

​​Component​​ ​​Supported Versions​​
Cisco Unified CM 12.5(1)SU5 and later
Cisco Unity Connection 12.5(1)SU2 and later
Virtualization Platforms VMware ESXi 7.0 U3, KVM (RHEL 9)
IP Phones 7841, 8865, DX80, Webex Desk Pro
Browser Support (Admin GUI) Chrome 126+, Edge 115+

​​Critical Considerations​​:

  • Requires CUCM 12.5(1)SU5 Security Patch Bundle 3 for full cryptographic compliance with Czech e-Government standards
  • Incompatible with Cisco Emergency Responder versions prior to 12.5(1)SU4 due to localized timestamp parsing conflicts
