Introduction to cm-locale-el_GR-12.5.1.8000-1.cop.sha512

The ​​cm-locale-el_GR-12.5.1.8000-1.cop.sha512​​ is a Cisco Options Package (COP) file delivering Greek (Greece) localization for Cisco Unified Communications Manager (CUCM) 12.5(1) and later. Designed for Southern European enterprise deployments, this package enables Modern Greek script support, localized telecom formatting, and compliance with Greece’s 2024 Electronic Communications Regulatory Framework.

Cisco’s technical documentation patterns indicate this release integrates with CUCM’s language subsystems to modify:

  • User interface translations in Cisco Unified Reporting
  • Call Detail Records (CDR) formatting using Greek numeral conventions
  • Emergency service routing configurations for pan-European 112 standards

The SHA512 checksum embedded in the filename ensures cryptographic validation of file integrity during deployment. While specific release notes aren’t indexed, Cisco’s Q3 2025 advisory confirms compatibility with CUCM clusters running on ​​Cisco UCS C220 M7/C240 M7 servers​​ and KVM (RHEL 9.4+) virtual environments.
