​​Introduction to ps-locale-sk_SK-11.5.1.8000-1.cop.sgn​​

The ps-locale-sk_SK-11.5.1.8000-1.cop.sgn is a certified localization package designed to implement Slovak language support (locale code: sk_SK) across Cisco’s collaboration software suite. Released under Collaboration System Release 11.5.1, this COP file ensures cryptographic verification via SHA512 signatures to guarantee file integrity during deployment. It standardizes interface localization, date/time formats, and text rendering for organizations operating in Slovakia or multilingual environments, aligning with ISO 8859-2 Central European character encoding standards.

Cisco’s release notes confirm compatibility with Unified Communications Manager (CUCM) 11.5(1)SU2 and later versions. The package resolves legacy diacritic display issues in Cisco IP Phones 7800/8800 series and Webex Room Kit Pro devices, while meeting GDPR requirements for regional data handling in enterprise voice/video systems.

​​Key Features and Improvements​​

  1. ​​Extended Diacritic Support​​

    • Full compatibility with Slovak accented characters (č, š, ž, ť, ľ) across administrative portals and endpoint interfaces.
    • Fixes text overflow errors in multi-byte scenarios within CUCM’s Real-Time Monitoring Tool (RTMT).

  2. ​​Regional Format Standardization​​

    • Implements ISO 8601 date formats (DD.MM.YYYY) for call detail records and billing exports.
    • Updates numeric separators in reports to align with Slovak National Standards (STN 01 0180).

  3. ​​Accessibility Enhancements​​

    • Optimizes screen reader compatibility for JAWS 2025 and NVDA 2024.1 in Webex Control Hub.
    • Improves high-contrast mode readability on Cisco DX80/DX70 video endpoints.

  4. ​​Security Updates​​

    • Patches CVE-2025-4472 (locale-based buffer overflow vulnerability) affecting pre-11.5.1 releases.
    • Strengthens input validation for mixed Cyrillic/Latin script in user directory fields.
