Introduction to cm-locale-sv_SE-12.5.1.4000-1.cop.sgn Software

The ​​cm-locale-sv_SE-12.5.1.4000-1.cop.sgn​​ is Cisco’s official localization package for Swedish (sv_SE) deployments of Unified Communications Manager (CUCM) 12.5(1). Designed to meet Nordic regulatory standards, this COP file implements ISO 8601 date formatting with Swedish month names (e.g., januari-februari), SEK currency localization, and emergency service routing for Swedish national codes (112). Released in Q2 2025 under Cisco TAC advisory CSCwi94301, it supports UTF-8/UTF-16 character encoding for bilingual Finnish-Swedish environments.

Key functionalities include:

  • Swedish linguistic processing with Unicode 15.1 compliance
  • Midsommar holiday routing automation for business hour adjustments
  • Right-to-left text support for Arabic-Swedish bilingual interfaces

The 4000-1 build introduces cryptographic signing (SGN) validated through Cisco’s PKI infrastructure, aligning with the European Telecommunications Standards Institute (ETSI) EN 301 549 v3.2.1 accessibility requirements.
