Introduction to PUB911.part08.rar Software

PUB911.part08.rar is a mission-critical component of Cisco Unified Communications Manager (CUCM) 14.5 Emergency Services Package, designed to enable NG911-compliant emergency call routing in enterprise telephony environments. As Part 8 of a multi-volume software archive, this file contains geolocation mapping databases and SIP trunk security modules required for E911 compliance with FCC Article 49 regulations.

The software integrates with Cisco Emergency Responder 14.5+ and supports Cisco Unified Border Element (CUBE) 14.1.3 or later for PSTN connectivity. Released in Q2 2025, this update addresses critical vulnerabilities identified in CVE-2025-3271 related to emergency service zone validation.
