Introduction to cm-locale-tr_TR-12.5.1.3000-1.cop.sgn

The ​​cm-locale-tr_TR-12.5.1.3000-1.cop.sgn​​ is an official localization component for Cisco Unified Communications Manager (CUCM) 12.5.1, specifically designed to enable full Turkish (Turkey) language compliance in enterprise voice systems. Released under Cisco’s Q1 2025 software updates, this package addresses regional requirements for call handling interfaces, administrative portals, and endpoint displays with Turkey-specific localization standards.

This software supports UTF-8 encoding for proper rendering of Turkish characters (Ğ/ğ, İ/i, Ş/ş) across Cisco IP Phones 7800/8800 series and Webex Room Kit Pro endpoints. It is validated for both on-premises CUCM clusters and cloud-based Cisco Webex Calling deployments running 12.5.1 SU2 or newer.
