​​Introduction to cm-locale-sr_RS-11.5.1.8100-1.cop.sgn​​

The ​​cm-locale-sr_RS-11.5.1.8100-1.cop.sgn​​ is a cryptographic-signed localization package for Cisco Unified Communications Manager (CUCM) 11.5(1), delivering native Serbian (Cyrillic/Latin) language support for administrative interfaces, user portals, and endpoint configurations. Designed under Cisco’s Regional Language Compliance Framework, this COP (Cisco Options Package) file enables enterprises in Serbia, Bosnia and Herzegovina, and Montenegro to align their UC systems with local linguistic and regulatory requirements.

This release addresses inconsistencies in prior versions (e.g., CUCM 10.5.2) where partial translations caused errors in the ​​Cisco Unified Reporting​​ tool and truncated text in the ​​Cisco Unified Serviceability​​ portal. The package complies with Unicode 14.0 standards to ensure accurate rendering of Serbian-specific characters like “ć,” “č,” and “š” across all interfaces.
