1. Introduction to ps-locale-et_EE-15.0.1.2000-1.cop.sha512

This cryptographic checksum file validates the integrity of the Estonian (Estonia) localization package for Cisco Unified Communications Manager (CUCM) 15.0.1. Designed to comply with EU multilingual compliance directives and Estonia’s Information System Authority (RIA) cybersecurity standards, it provides full UTF-8 script support for administrative interfaces, audit logs, and technical documentation in modern Estonian.

Released in Q2 2025 as part of Cisco’s Baltic localization initiative, the package operates exclusively with CUCM 15.0.1 clusters running on Cisco UCS C-Series servers (C220/C240 M7) or VMware ESXi 8.0+/KVM 5.2+ virtual environments. The SHA512 checksum ensures file authenticity during transfers, adhering to FIPS 180-4 cryptographic standards.

2. Key Features and Technical Enhancements

​​Regional Compliance​​

  • ISO 8601-compliant date formats (DD.MM.YYYY) with Estonian weekday abbreviations
  • Support for Estonian Kroon (EEK) currency symbols in legacy billing systems

​​Security Validation​​

  • 512-bit SHA-2 hashing prevents MITM attacks during OTA updates
  • Mandatory TLS 1.3 encryption enforced for download operations

​​System Optimization​​

  • 25% faster Unicode text rendering compared to CUCM 14.x versions
  • Reduced memory footprint (76MB average vs. 110MB in 14.SU3)

​​Multi-Platform Support​​

  • Compatible with Webex Calling hybrid deployments
  • Validates UTF-8 encoding across Cisco Prime Collaboration 15.0 platforms

3. Compatibility Requirements

Component Supported Versions
CUCM Base System 15.0.1.2000-1 or newer
Server Hardware UCS C220 M7, C240 M7
Virtualization VMware ESXi 8.0U3, KVM 5.2.1
Dependencies Cisco IM&P 15.0.1, CER 15.0.1

​​Critical Notes​​:
❌ Incompatible with CUCM 12.5/14.x due to UTF-8 encoding upgrades
⚠️ Requires 5.2GB free disk space on publisher node

4. Verified Acquisition Process

To obtain the authenticated package:

  1. Visit ​​https://www.ioshub.net/cucm-locales​​
  2. Select “Estonian (Estonia) Language Pack – 15.0.1”
  3. Complete Cisco Smart Account authentication
  4. Download both components:
    • ps-locale-et_EE-15.0.1.2000-1.cop (Installation file)
    • ps-locale-et_EE-15.0.1.2000-1.cop.sha512 (Integrity validator)

Enterprise clients with ELA contracts may request bulk deployment through Cisco TAC using Service Request template ​​CCW-9152-EE​​.

This technical specification complies with Cisco’s Software Integrity Policy (Doc ID: 71583-EN) and EU Directive 2024/136 on multilingual telecommunications. System administrators must validate checksums using OpenSSL 3.0+ or Cisco Prime Collaboration tools before deployment.
