Introduction to cme10.tar
The cme10.tar is a critical localization package for Cisco Unified Communications Manager Express (CME) deployments, specifically designed to enable multilingual support on Cisco ISR 4000 Series routers running IOS XE 17.12.x. Released on March 15, 2025, this TAR archive contains Simplified Chinese, Arabic, and Russian language packs alongside updated SIP device templates for international enterprise deployments.
This package extends CME’s capabilities in hybrid UC environments by providing localized web interfaces, IVR prompts, and XML service files compliant with RFC 5646 language tags. Compatible with CUCM versions 14.5SU3+ and CME 15.0(1)M9+, it addresses localization requirements for multinational corporations operating under ITU-T E.123 numbering standards.
Key Features and Improvements
1. Multilingual System Integration
- WebUI Localization: Full translation of CME administration portals into 3 new languages
- Dynamic Codec Prioritization: Auto-selects G.722.1C for Chinese locales vs Opus 1.3 for Cyrillic regions
- XML Service Overhaul: UTF-8 encoded SEP.cnf.xml files with locale-specific DHCP options
2. Security Enhancements
- CVE-2025-3031 Mitigation: Patches XSS vulnerabilities in language pack installation workflows
- TLS 1.3 Compliance: Replaces deprecated SSLv3 in localized web authentication modules
- FIPS 140-3 Validation: Hardware-rooted encryption for translated configuration backups
3. Performance Optimizations
- 30% faster SIP message processing in multilingual environments
- Reduced memory footprint through zlib-optimized TAR compression (avg. 42% size reduction)
- Parallel localization loading for Cisco 7975G/8865NR IP phones
