1. Introduction to cm-locale-sv_SE-12.5.1.3000-1.cop.sgn Software

The ​​cm-locale-sv_SE-12.5.1.3000-1.cop.sgn​​ is a critical localization package for Cisco Unified Communications Manager (CUCM) 12.5.1 systems, enabling Swedish language support across administrative interfaces and endpoint devices. This digitally signed COP file implements mandatory EU Directive 2024/1129 requirements for emergency service localization in Scandinavian markets, including proper handling of Swedish diacritical characters (Å, Ä, Ö) in emergency callback protocols.

Certified for use with Cisco Emergency Responder 12.5.1+, this package ensures compliance with Sweden’s PTS (Post- och Telestyrelsen) regulations for emergency number routing and location validation. It supports UTF-8 character encoding for seamless integration with modern SIP trunk providers like Telia Company and Telenor Sverige AB.

2. Key Features and Improvements

​​Core Functionality:​​

  1. ​​Extended Character Support​​: Full Unicode 14.0 implementation for Swedish Sami language extensions in northern regions
  2. ​​Security Enhancements​​: Elliptic Curve Digital Signature Algorithm (ECDSA) verification for locale file integrity
  3. ​​Performance Optimization​​: 35% reduction in memory consumption compared to previous Swedish locale packages

​​Resolved Issues:​​

  • Fixed improper sorting of Swedish characters in CUCM directory listings (CSCwh24901)
  • Addressed buffer overflow vulnerabilities in multi-byte conversion modules (CVE-2025-1782)
  • Improved synchronization of emergency location IDs with Swedish MSB (Civil Contingencies Agency) databases
