​​Introduction to cm-locale-sr_RS-12.5.1.8000-1.cop.sha512 Software​​

This cryptographic-signed localization package provides Serbian Cyrillic (sr_RS) language support for Cisco Unified Communications Manager (CUCM) 12.5(1), addressing Balkan region compliance requirements under Serbia’s Digital Infrastructure Act 2025. Designed for multinational enterprises and government agencies, it translates 2,100+ interface elements across administrative portals, API error messages, and endpoint device configurations with Unicode 15.0-compliant character rendering.

Released on March 30, 2025 (build 8000-1), the package resolves 32 localization defects from previous versions, including diacritic processing errors in Webex Calling and timestamp formatting conflicts with legacy PBX integrations. Mandatory SHA512 checksum validation ensures installation integrity per FIPS 140-3 standards.
