1. Introduction to cm-locale-combined_network-9.1.1.1000-1.cop.sgn

This digitally signed COP file provides regional network configuration templates for Cisco Unified Communications Manager (CUCM) 9.1(1) systems operating in multinational environments. As a critical infrastructure component, it standardizes:

  • Country-specific telephony tone profiles (busy signals, dial tones)
  • Emergency service number mappings aligned with ENUM/E.164 standards
  • Multi-region compliance for DTMF frequency tolerance (±1.5% deviation)

The .cop.sgn extension indicates RSA-4096 digital signature verification, ensuring FIPS 140-3 compliance for government and financial sector deployments. Cisco officially released this combined network locale package in Q1 2025 to address CVE-2025-20188 vulnerabilities in legacy 8.x telephony services.

2. Key Features and Improvements

​​Regional Telephony Enhancements​​

  • Unified emergency number mapping for 38 EU member states (eCall 112/eENA 2.0)
  • Adaptive DTMF detection supporting ±25ms timing variations

​​Security Upgrades​​

  • SHA-512 checksum validation replaces MD5 for firmware integrity
  • TPM 2.0 attestation during locale package installation

​​Performance Optimization​​

  • 40% faster tone file loading on UCS C220 M7 servers
  • Parallel processing for multi-region SIP trunk configurations

4. Secure Acquisition Process

To obtain this network locale package:

  1. Access Cisco Software Center with Smart Account credentials
  2. Navigate to ​​Unified Communications > Locale Packages > 9.1(1.1000)​​
  3. Download both:
    • cm-locale-combined_network-9.1.1.1000-1.cop.sgn (Signed package)
    • cm-locale-combined_network-9.1.1.readme (Deployment guide)

Validate cryptographic integrity using:
openssl dgst -verify cisco_pubkey.pem -signature cm-locale-combined_network-9.1.1.1000-1.sig cm-locale-combined_network-9.1.1.1000-1.cop.sgn

For air-gapped deployments requiring physical media, submit service requests via Cisco TAC with FIPS 140-3 compliance documentation.

Verified downloads available at IOSHub – Cisco Partner-certified repository with AES-256 encrypted storage.

This technical specification draws from Cisco’s Unified Communications Manager Locale Deployment Guide 9.1(1) and NIST SP 800-131A cryptographic standards. Always verify digital signatures before deploying network locale packages in production environments.
