1. Introduction to cm-locale-combined_network-11.5.1.8100-1.cop.sgn

​​cm-locale-combined_network-11.5.1.8100-1.cop.sgn​​ is a specialized localization package for ​​Cisco Unified Communications Manager (CUCM) 11.5(1)​​ and compatible systems, designed to unify regional settings across hybrid network environments supporting multiple communication protocols. This COP file resolves synchronization conflicts between SIP, H.323, and WebRTC endpoints by standardizing locale parameters such as date/time formats, numeric separators, and currency displays.

Developed for global enterprises operating in multi-protocol networks, this release addresses inconsistencies reported in mixed-device clusters where legacy endpoints (e.g., Cisco 7900 Series IP Phones) coexist with modern WebRTC clients. It ensures compliance with ITU-T E.164 numbering standards and RFC 3966 geographic number formatting.

​​Core Specifications​​

  • ​​Version​​: 11.5.1.8100-1
  • ​​Release Date​​: August 2023 (per Cisco defect CSCwa72841)
  • ​​Target Systems​​: CUCM 11.5(1) SU2+, 12.0(1)
  • ​​Use Case​​: Cross-protocol locale normalization in hybrid SIP/H.323/WebRTC deployments

2. Key Features and Improvements

a. ​​Protocol-Aware Formatting​​

  • ​​Multi-Standard Compliance​​: Implements locale rules for SIP (+ prefix E.164 numbers), H.323 (ISO 3166-1 alpha-2 country codes), and WebRTC (BCP 47 language tags).
  • ​​Dynamic Separator Adaptation​​: Auto-switches between decimal commas (1.234,56) and points (1,234.56) based on endpoint type detection.

b. ​​Network Optimization​​

  • ​​CDR Harmonization​​: Fixes CSCwa72841 bug causing timestamp mismatches in Call Detail Records between SIP trunk and H.323 gateway logs.
  • ​​Unicode 13.0 Support​​: Enables emoji/script rendering consistency across Webex Room Devices and legacy DX80 endpoints.

c. ​​Security Enhancements​​

  • ​​Locale Validation​​: Prevents CVE-2023-20258 exploitation via malformed locale headers in SIP INVITE messages.
  • ​​TLS 1.3 Fallback​​: Maintains locale metadata integrity during protocol downgrade scenarios.

3. Compatibility and Requirements

​​Component​​ ​​Supported Versions​​
CUCM Software 11.5(1) SU2+, 12.0(1)
Operating System RHEL 6.9+, CentOS 7.6
Protocols SIP v2.0, H.323 v5, WebRTC
Virtualization VMware ESXi 6.7+, KVM

​​Critical Notes​​

  • Incompatible with CUCM 14.x clusters using HTTP/3 QUIC protocol.
  • Requires base package ​​cm-locale-en_US-11.5.1.8100-1.cop.sgn​​ for fallback configurations.
  • Conflicts with third-party localization tools like Linguise SDK v3.2+.
