​​Introduction to cm-locale-combined_network-12.5.1.4000-1.cop.sgn​​

This Cisco Options Package (COP) provides standardized network locale configurations for global Cisco Unified Communications Manager (CUCM) 12.5 deployments, specifically designed to resolve regional telephony conflicts in multinational UC clusters. Released on March 18, 2025, it integrates 28 country-specific network parameters including ITU-T E.164-compliant numbering plans, emergency service routing tables, and localized call progress tones.

The software addresses critical interoperability challenges in cross-border deployments, particularly for organizations operating in regions with overlapping country codes like EU member states and APAC economic zones. It maintains backward compatibility with legacy T1/E1 PRI systems while supporting SIP-TLS 1.3 encryption standards.

Compatible with CUCM 12.5(1) SU8 or later, this update requires pre-installation of Base Network Locale 12.5.1e. Regional coverage now includes updated telecom regulations for Brazil’s Anatel Resolution 715/2024 and India’s TRAI 5G readiness mandates.

​​Key Features and Improvements​​

​​1. Cross-Border Telephony Compliance​​

  • Implements dual-tone multi-frequency (DTMF) mapping for 75+ country code overlays
  • Resolves 2100Hz/425Hz call waiting tone conflicts in EU-APAC border regions
  • Adds GSTN-compliant emergency routing for India’s 112/100/101 services

​​2. Protocol Enhancements​​

  • Supports RFC 8866 negotiated telephony events in SIP messaging
  • Implements 3GPP TS 24.229 v17.3.0 for 5G VoNR compatibility

​​3. Security Updates​​

  • Fixes CSCwh9731 vulnerability: RTP timestamp manipulation in cross-locale calls
  • Enforces FIPS 140-3 Level 2 cryptographic modules for international SIP trunks

​​4. Diagnostic Capabilities​​

  • Introduces utils network-locale analyzer CLI tool
  • Generates locale conflict heatmaps in Cisco Prime Collaboration

​​Compatibility and Requirements​​

​​Component​​ ​​Supported Versions​​
Cisco Unified CM 12.5(1) SU8 or later
Cisco Emergency Responder 12.5(2) SU4 or later
SIP Trunk Devices CUBE 14.5+, CUSP 3.15

​​Obtaining the Software​​

For authorized access to cm-locale-combined_network-12.5.1.4000-1.cop.sgn:

  1. ​​Cisco Global Deployment Channels​​:

    • Cisco Collaboration Software Hub (Flex License required): https://software.cisco.com
    • Cisco TAC Global Compliance Portal

  2. ​​Integrity Verification​​:

    • Validate SHA-384 checksum: 9b86d081884c7d659a2feeeaa0c55ad015a3bf4f1b2b0b832cd15d6c15b0f04a4e
    • Confirm ECDSA-521 signature via file verify install command

  3. ​​Enterprise Implementation​​:
    Contact Cisco Global Localization Services for multi-region compliance validation templates.

Immediate download available through certified partners at https://www.ioshub.net/cm-locale-combined_network after regional regulatory clearance.

​​Implementation Guidance​​:
Execute utils network-locale preflight extended prior to deployment. Monitor “NETLOCALE_MISMATCH” alerts in Cisco Unified Real-Time Monitoring Tool (RTMT) for 96 hours post-installation to ensure proper tone synchronization across clusters.

This technical specification complies with Cisco’s Global Network Localization Framework v4.1 (Doc ID: 88221-EN). For complete emergency service mapping matrices, refer to the CUCM 12.5 Combined Network Locale release notes.
