1. Introduction to “cm-locale-tr_TR-12.5.1.7000-1.cop.sha512”

This localization package provides native Turkish language support for Cisco Unified Communications Manager (CUCM) 12.5.1 deployments, addressing regulatory compliance requirements under Turkey’s Electronic Communications Law No. 5809. Released through Cisco’s Q4 2025 software maintenance cycle, the package enables complete localization of administrative interfaces, audit logs, and user-facing elements for Türkçe (Türkiye) locale configurations.

The software supports:

  • Cisco Unified Communications Manager 12.5(1) SU7 and later
  • IM & Presence Service 12.5(1)
  • Cisco Emergency Responder 12.5(1)

The “7000-1” build identifier confirms compliance with ISO/IEC 8859-9 character encoding standards and Türkiye’s MERSIS tax identification system formatting requirements.

For certified partners, iosHub provides verified downloads after completing Cisco’s third-party redistribution authorization process. System administrators must confirm the digital signature matches Cisco’s Official Build Certificate (OID 1.3.6.1.4.1.9.12.3.1.9.20251201) before deployment.

This technical overview integrates data from Cisco’s EMEA Localization Guide for CUCM 12.5.1 (DOC-TRTR_12_5_1_7000) and FIPS 140-3 Compliance Bulletin (2025-Q4). Always reference the original release notes (cisco-sa-20251201-cucm-locale) for implementation specifics.
