1. Introduction to cmterm-s52010ce9_15_13_0.k3.cop.sgn Software

This critical firmware package enables SIP protocol functionality on Cisco 52010 Series IP Phones within Unified Communications Manager (CUCM) environments. Released on March 15, 2025, it resolves 9 CVEs identified in previous SIP device packages while introducing enhanced security protocols.

The software supports legacy 52010 phone models including:

  • Cisco Unified IP Phone 52010G (Gigabit Ethernet variant)
  • Cisco Unified Wireless IP Phone 52010W
  • 52010-VP (Video Phone Edition)

Key operational improvements include TLS 1.3 handshake optimization and SRTP media encryption enhancements, ensuring compliance with NIST SP 800-121C standards for enterprise voice systems.
