Introduction to ps-locale-tr_TR-12.5.1.5000-1.cop.sgn
The ps-locale-tr_TR-12.5.1.5000-1.cop.sgn is an official Cisco localization package enabling Turkish (Turkey) language support for Cisco Unified Communications Manager (CUCM) 12.5.1 systems. Released on September 5, 2025, this COP file implements ISO 639-1:2023-compliant translations for administrative interfaces, device configurations, and API responses, tailored to Turkey’s regional standards. Designed for enterprises operating in Turkish-speaking markets, it addresses compliance requirements under Turkey’s Information and Communication Technologies Authority (BTK) for localized telecommunications systems.
This language pack integrates with hybrid deployments combining on-premises CUCM clusters and Webex Calling services, ensuring consistent UI translations for Cisco IP Phone 8800 Series endpoints and Webex App users.
