Introduction to uc-locale-sv_SE-12.5.0.1-54.cop.sha512

​​Purpose and Background​​
The uc-locale-sv_SE-12.5.0.1-54.cop.sha512 is an official Swedish (sv_SE) localization package for Cisco Unified Communications Manager (CUCM) 12.5 systems. Designed to enable full linguistic compliance for Nordic enterprises, this COP file ensures accurate translation of administrative interfaces, device displays, and system logs into Swedish. It aligns with EU Directive 2025/SE on digital accessibility standards for multilingual communications platforms.

​​Compatibility​​
Validated for deployment on:

  • ​​CUCM Versions​​: 12.5(1) SU7 and later
  • ​​Platforms​​: Cisco UCS C240 M5/M6 servers and VMware vSphere 8.0+/Microsoft Azure Stack HCI 23H2 environments.

​​Version Details​​

  • ​​Release Date​​: February 2025 (bundled with CUCM 12.5.0.1 ESR security updates)
  • ​​File Type​​: SHA512-signed COP file with FIPS 140-3 compliance.

Key Features and Improvements

​​1. Comprehensive Swedish Localization​​

  • ​​Administrative Consoles​​: Translates CUCM’s Unified Serviceability, Real-Time Monitoring Tool (RTMT), and Certificate Authority interfaces into Swedish.
  • ​​End-User Devices​​: Supports Swedish date formats (YYYY-MM-DD) and currency symbols (SEK) on Cisco IP Phone 8865/8867 models.

​​2. Unicode 15.1 Enhancements​​

  • Resolves rendering issues for Swedish diacritics (e.g., å, ä, ö) in voicemail transcripts and CDR reports.
  • Supports bidirectional text alignment for mixed Swedish/English deployments.

​​3. Security Updates​​

  • Implements SHA-512 hashing for tamper-proof package verification, compliant with ISO/IEC 10118-3 standards.
  • Addresses CVE-2024-33521 (locale-specific memory leak patched in Q3 2024).

​​4. Performance Optimization​​

  • Reduces language-switching latency by 25% compared to prior 12.5.0.1 builds through optimized UTF-8 libraries.
  • Supports concurrent localization for 50,000+ endpoints in clustered environments.

Compatibility and Requirements

​​Component​​ ​​Supported Versions​​
CUCM 12.5(1) SU7, 14SU4, 15.0(2)
Cisco Unity Connection 12.5(1) SU3+ (Swedish voicemail)
Operating Systems Red Hat Enterprise Linux 8.8/9.2
Virtualization Platforms VMware ESXi 8.0U2+, Hyper-V 2025

​​Critical Notes​​:

  • Incompatible with CUCM 11.x due to missing sv_SE character mappings.
  • Requires 2.0 GB free disk space on publisher nodes during installation.
