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

This locale pack enables Serbian (Latin) language support for Cisco Unified Communications Manager (CUCM) deployments, specifically targeting administrative interfaces and end-user portals. Released under Cisco’s Internationalization initiative, it addresses regional compliance requirements for organizations operating in Serbia and neighboring Balkan regions. The package follows Cisco’s standardized COP file format for modular software components, ensuring compatibility with CUCM versions 12.5.1 and later.

As per Cisco’s regionalization guidelines, this update implements SR_RS (Serbian Latin) locale codes per ISO 639/3166 standards, including date/time formats, numeric conventions, and Unicode mapping for Cyrillic-Latin transliteration in hybrid environments.

  2. ​​Localization Enhancements​​

    • Native display of Serbian VAT/tax formats in CDR reports
    • Time zone synchronization with Belgrade (CET/CEST) daylight saving rules
