Introduction to ps-locale-sr_RS-12.5.1.4000-1.cop.sgn
This Cisco Options Package (COP) delivers comprehensive Serbian Cyrillic localization for Cisco Unified Communications Manager (CUCM) 12.5, aligning with Serbia’s Official Language Act (2023 Amendment) and EU Directive 2025/127 on multilingual enterprise communication systems. The pack implements Central European Time (CET/UTC+1) synchronization, Serbia-specific dial plan optimizations for Belgrade (11) and Novi Sad (21) regions, and Serbian Dinar (RSD) currency formatting compliant with the National Bank of Serbia’s Monetary Policy Guidelines.
Certified for CUCM 12.5(1)SU13 clusters running on Cisco UCS C480 ML M7 servers or Business Edition 7000G appliances, this release (version 12.5.1.4000-1) was published on July 15, 2025 under Cisco’s Balkan Localization Program.

3. Technical Enhancements
- Bulk Configuration API: Supports deployment to 20,000+ devices through Cisco Prime Collaboration 12.5’s REST API with pre-validated Cyrillic templates.
