Introduction to cme-8.6-locale.zip Software

Cisco’s ​​cme-8.6-locale.zip​​ serves as a critical localization package for Unified Communications Manager Express (CME) 8.6, designed to enable multilingual support in voice infrastructure deployments. This software component provides localized text prompts, language-specific IVR templates, and regional telephony compliance features for Cisco IOS-based routers functioning as call processing agents.

Compatible with Cisco 3900/2900 ISR G2 series and legacy 2800/3800 routers running IOS 15.1(4)M6 or later, this package supports 12 languages including Simplified Chinese, Spanish, and French. The 8.6 version released in Q3 2020 introduced extended compatibility with SIP-based IP phones like CP-8845 and CP-7861.
