Introduction to term62.default.loads Software

This configuration package provides factory-default settings for Cisco Unified IP Phone 7962 devices utilizing Skinny Client Control Protocol (SCCP) in Unified Communications Manager (CUCM) environments. The “default.loads” extension indicates it contains standardized firmware parameters for device initialization and recovery operations.

Compatible with CUCM versions 8.6 to 11.5, this package serves two primary functions:

  1. ​​Device Provisioning​​ – Automates baseline configuration deployment during mass deployments
  2. ​​Troubleshooting Reset​​ – Restores corrupted devices to Cisco-validated operational states

Cisco’s archived technical bulletins indicate this package was last updated in Q4 2020 to address security vulnerabilities in legacy SCCP implementations.

Key Features and Improvements

  1. ​​Protocol Standardization​​

    • Optimized SCCP v17 heartbeat intervals (30-300s adjustable range)
    • Default QoS tagging for voice traffic (DSCP 46 prioritization)
    • Preset codec negotiation sequence: G.711μ-law > G.729a > G.722

  2. ​​Security Baseline​​

    • Disabled TLS 1.0/1.1 protocols by default
    • Preconfigured digest authentication for XML services
    • Disabled web interface access in production mode

  3. ​​Device Management​​

    • Preloaded corporate directory templates
    • Standardized button mappings for 7962’s 6-line LCD display
    • TFTP fallback timeout set to 120 seconds

  4. ​​Compliance Updates​​

    • Emergency service number labels (911/112/999) localized for North American/EU markets
    • Default NTP servers synchronized to Cisco’s stratum-2 time sources

Compatibility and Requirements

Component Supported Versions Notes
IP Phone Hardware 7962G Excludes 7961/7965 models
CUCM 8.6-11.5 Requires TFTP service activation
Switch Platforms Catalyst 2960/3560/3750 PoE Class 2 minimum
IOS 15.1(2)SY+ LLQ configuration mandatory

​​Critical Dependencies​​:

  • Cisco Unified Communications Manager SCCP Device License
  • 512MB+ TFTP server storage per 50 devices
  • Disabled SIP ALG on network firewalls

Limitations and Restrictions

  1. ​​End-of-Support Considerations​​

    • No security updates provided after 2022
    • Incompatible with CUCM 12.x+ clusters

  2. ​​Functional Constraints​​

    • Maximum 6 concurrent SCCP sessions per device
    • No video/encrypted call support
    • Preset configurations cannot integrate third-party PBX systems

  3. ​​Deployment Requirements​​

    • Manual XML customization required for advanced features
    • Physical reset button must be enabled during provisioning
    • DHCP option 150/66 must point to CUCM TFTP server

Obtaining the Configuration Package

Authorized Cisco users can access ​​term62.default.loads​​ through:

  1. ​​Cisco Software Center​​
    Navigate path: Collaboration Endpoints > IP Phones > 7900 Series > SCCP Configuration Files
    Direct portal: software.cisco.com/download

  2. ​​Legacy Support Providers​​
    Verified partners like IOSHub maintain archival repositories for EoL devices

​​Verification Protocol​​: Always validate MD5 checksum against Cisco’s published value (A3F9B…C71D) before deployment.

This technical overview synthesizes information from Cisco’s 7900 Series IP Phone Administration Guides and SCCP Configuration Best Practices documentation. System administrators should reference the original CUCM 11.5 release notes for VLAN configuration specifics and known issue resolutions.
