Introduction to “cm-locale-sv_SE-12.5.1.3000-1.cop.sgn”

The “cm-locale-sv_SE-12.5.1.3000-1.cop.sgn” is an official localization package for Cisco Unified Communications Manager (CUCM) 12.5.x deployments requiring Swedish language support. Designed under Cisco’s global accessibility initiative, this digitally signed COP file provides translated user interfaces, voice prompts, and region-specific formatting for Swedish-speaking users across CUCM clusters.

Compatible with CUCM 12.5(1)SU6 and later releases, this package addresses localization gaps identified in Cisco’s 2024 Q4 internationalization audit. Released on January 17, 2025, version 12.5.1.3000-1 introduces enhanced Unicode 14.0 compliance for modern Swedish orthography requirements.
