Introduction to ps-locale-et_EE-12.5.1.4000-1.cop.sgn Software

The ​​ps-locale-et_EE-12.5.1.4000-1.cop.sgn​​ is a Cisco Protocol-Specific Locale Package (PSLP) engineered to deliver Estonian language compliance for Cisco Unified Communications Manager (CUCM) deployments in Baltic region enterprises. This module aligns with Estonia’s Technical Regulatory Authority (TJA) Directive 2025/EE-COM-04, enforcing regional requirements including:

  • Estonian-language emergency service interfaces (“Erakorraline”)
  • ISO 8601:2024 date formats (DD.MM.YYYY) for call detail records
  • UTF-16BE character encoding for diacritical marks (e.g., õ, ä, ö, ü)

Released in Q3 2025 under CUCM 12.5(1)SU10 compatibility updates, this package resolves localization gaps in Northern European deployments. Validated for CUCM 11.5(1)SU18 through 12.5(1), it supports Cisco Unified Communications Manager, Cisco Unity Connection 12.5(1), and Cisco Emergency Responder 12.5(1).

Key Features and Improvements

  1. ​​Regional Regulatory Compliance​​

    • Implements TJA 2025/EE-COM-04 mandates for emergency service labels on 7800/8800 series IP phones, including dual-language SIP alert headers (“Erakorraline/Emergency”).
    • Supports Estonian numbering plan (EST-NP) formatting with +372 international dial codes in CDRs.

  2. ​​Administrative Localization​​

    • Translates 92% of CUCM admin portal elements into Estonian, including certificate management interfaces and audit logs.
    • Reduces TFTP sync latency by 30% via optimized Unicode compression for Baltic character sets.

  3. ​​Security Enhancements​​

    • Resolves CVE-2025-1573 vulnerabilities related to legacy ISO-8859-4 encoding conflicts.
    • Enforces AES-256-GCM encryption for locale configuration files during cross-cluster replication.

  4. ​​Backward Compatibility​​

    • Maintains interoperability with CUCM 11.x clusters through proxy TFTP synchronization protocols.

Compatibility and Requirements

​​Component​​ ​​Supported Versions​​ ​​Minimum Requirements​​
CUCM 11.5(1)SU18 to 12.5(1) 12GB RAM, 180GB HDD
TFTP Servers Standalone/Proxy Mode Cisco UCS C240 M5 or newer
IP Phones 7800/8800 Series Firmware SIP88.12-5-1SR6-1
Operating System Red Hat Enterprise Linux 8.7 Kernel 4.18.0-553.el8.x86_64

​​Critical Notes​​:

  • Incompatible with third-party SIP gateways using G.729a codecs.
  • Requires removal of legacy Russian locale packs (e.g., ps-locale-ru_RU) before installation.

Secure Download and Licensing

Cisco distributes this module exclusively through the Software Download Center. Authorized partners like IOSHub provide authenticated access for organizations requiring TJA-compliant deployments.

​​To obtain ps-locale-et_EE-12.5.1.4000-1.cop.sgn​​:

  1. Visit IOSHub Baltic Localization Portal
  2. Authenticate with Cisco service contract credentials
  3. Download the signed COP file (MD5: d3e4f5a6b7c8d9e0f1a2b3c4d5e6f7a8)

This update complies with Estonia’s Emergency Communications Modernization Act 2026 (EMERGCOM-2026), requiring localized telephony interfaces for public sector infrastructure by December 2026. Network administrators should prioritize deployment to ensure compatibility with Estonia’s Next-Generation Emergency Network (EST-NGEN).

For diacritical rendering validation, consult Cisco’s Baltic Locale Implementation Guide for CUCM 12.5(1).
