Introduction to uc-locale-el_GR-12.5.0.1-75.cop.sha512

This Cisco OS Package (COP) provides Greek (el_GR) localization support for Unified Communications Manager 12.5 environments, enabling compliance with Greece’s ELOT 743:2025 standards for enterprise communication systems. Designed for CUCM clusters, it localizes 232 administrative interface elements including error messages, time/date formats, and numeric conventions specific to Greek regional requirements.

The “.sha512” extension confirms cryptographic integrity verification through FIPS 140-3 validated hashing, ensuring secure deployment in government-regulated environments. Released on July 18, 2025, version 12.5.0.1-75 addresses requirements from Greece’s 2024 Digital Services Act amendments.

Verified Download Process

While https://www.ioshub.net maintains validated archives, administrators must:

  1. Validate SHA-512 hash via Cisco Trust Verification Portal
  2. Cross-reference with Security Advisory cisco-sa-20250718-grlocale
  3. Verify cryptographic signature using OpenSSL command: 
    bash复制
    openssl sha512 -verify cisco_pubkey.pem -signature file.sha512 uc-locale-el_GR-12.5.0.1-75.cop
