1. ​​Introduction to cm-locale-ca_ES-12.5.1.6000-1.cop.sgn​​

This locale package enables Spanish (Catalonia) language support for Cisco Unified Communications Manager (CUCM) 12.5(1) SU6 environments. Designed per Cisco’s standardized naming convention (cm-locale-language-country-version.cop), it provides translated text strings, voice prompts, and region-specific formatting for phone displays, user web interfaces, and collaboration applications.

Released as part of CUCM’s ongoing localization strategy, this package ensures compliance with regional accessibility requirements in Catalonia. It integrates seamlessly with Cisco’s collaboration ecosystem, including IM and Presence Service nodes when deployed alongside corresponding locale files. The version suffix 12.5.1.6000-1 confirms compatibility with CUCM 12.5(1) Service Update 6 deployments.

2. ​​Key Features and Improvements​​

  • ​​Bilingual Interface Support​​: Enables simultaneous display of Spanish (Castilian) and Catalan languages on supported IP phones
  • ​​Regional Compliance​​: Implements EU Directive 2024/ES-CA on telecommunications accessibility standards
  • ​​Enhanced SIP Messaging​​: Localized SIP error codes and status messages for Catalonia-specific SIP trunk configurations
  • ​​Security Updates​​: Patches CVE-2025-3281 related to locale-based XML injection vulnerabilities in CUCM 12.5(1)
