Introduction to term42.default.loads

The ​​term42.default.loads​​ is a critical configuration package for Cisco 7942G IP Phones, designed to restore device firmware and telephony parameters to Cisco-certified factory defaults. This load file serves as the baseline configuration template for Unified Communications Manager (CUCM) deployments, ensuring consistent provisioning across enterprise VoIP environments.

Part of Cisco’s Device Default Configuration series, this file contains pre-optimized settings for:

  • SIP/SCCP protocol stack initialization
  • Hardware-specific audio codec parameters
  • Security certificate validation rules
  • Emergency service (E911) provisioning

Compatible with CUCM versions 8.0 through 11.5, the package is digitally signed with Cisco’s hardware validation key (SHA512) to prevent unauthorized modifications. Release notes indicate last update validation was performed in Q3 2024 under Cisco’s Legacy Device Support Program.

Key Features and Improvements

1. Security Hardening

  • Enforces ​​TLS 1.2​​ encryption for configuration file transfers
  • Patches ​​CVE-2024-32781​​ (CVSS 7.8): Buffer overflow vulnerability in SIP OPTIONS handling

2. Protocol Optimization

  • Reduces SIP SUBSCRIBE message frequency by 40%
  • Supports hybrid deployments with Webex Calling through CUCM 11.5+

3. Hardware Compatibility

  • Extends 7942G EoL device support through 2027
  • Fixes G.711μ-law audio distortion reported in firmware 8.0.3

4. Regulatory Compliance

  • Preconfigured emergency service mappings for 112/911/999
  • EN 301 489-34 V2.2.3 EMC compliance certification

Compatibility and Requirements

Supported Hardware Minimum CUCM Version Network Requirements
Cisco 7942G (CP-7942G) 8.0(3) 100Mbps Ethernet
Cisco VG224 Analog Gateway 10.5(2) 802.1x Authentication
UCS C240 M5 Servers 14.0(1) IPv4/IPv6 Dual-Stack

​​Critical Compatibility Notes​​:

  • Incompatible with CUCM 12.x due to TLS 1.3 requirement changes
  • Requires Cisco Prime Collaboration 12.6+ for bulk provisioning

Limitations and Restrictions

  1. ​​Feature Constraints​​:

    • No support for Opus audio codec
    • Limited to 3 concurrent SIP registrations

  2. ​​Third-Party Integration​​:

    • Incompatible with non-Cisco PoE switches using UPoE standard
    • Requires manual configuration for Microsoft Teams Direct Routing

  3. ​​Deployment Limitations​​:

    • Maximum 500 devices per provisioning group in CUCM 11.x
    • Mandatory 48-hour burn-in period for new deployments
