Introduction to cm-locale-sr_RS-12.5.1.5000-1.cop.sgn

This Cisco Operations Package (COP) delivers comprehensive Serbian (Latin) localization for ​​Cisco Unified Communications Manager (CUCM) 12.5.1​​ administrative interfaces and user portals. Officially released on April 25, 2025, it addresses Balkan region compliance requirements by translating 8,200+ GUI elements and 97% of system alerts into standardized Serbian (sr_RS). Compatible with CUCM clusters running ​​12.5(1)SU4​​ or later, the pack supports Cyrillic/Latin script conversion for emergency service labels per Serbia’s RATEL 2024-12 telecommunications directive.

2. ​​User Experience Enhancements​​

  • Translates 100% of CUCM’s Real-Time Monitoring Tool (RTMT) interface with Unicode 14.0 support.
  • Adds Serbian dinar (RSD) currency formatting in CDR billing exports.
