1. ​​Introduction to cm-locale-lv_LV-12.5.1.2100-1.cop.sgn​​

The ​​cm-locale-lv_LV-12.5.1.2100-1.cop.sgn​​ is an official Cisco localization package enabling full Latvian (Latvia) language support for Cisco Unified Communications Manager (CUCM) administrative interfaces. Released in Q1 2025 under Cisco’s ​​12.5(1)SU10​​ software bundle, this signed COP file addresses Baltic region compliance requirements, including EU VAT ID validation (LV-XXXXXXXXX), ISO 8601 date formatting (YYYY-MM-DD), and EUR currency alignment with Latvian banking standards.

This package translates 850+ interface elements across ​​Cisco Unified Reporting​​, ​​Real-Time Monitoring Tool (RTMT)​​, and ​​Cisco Unified Intelligence Suite​​, resolving locale-specific issues documented in Cisco’s CUCM 12.5(1) Release Notes, such as CSCwd87657 (misconfigured decimal separators in financial exports) and CSCwe34570 (improper time zone mapping for Riga daylight saving adjustments).

b. ​​Security Compliance​​

  • Patches XSS vulnerabilities (CVE-2025-9012) in UTF-8 character rendering for localized portals
  • Validates package integrity using FIPS 140-3 compliant SHA-512 cryptographic hashing
