1. Introduction to JabberGuest-10.6.5.65.iso

The JabberGuest-10.6.5.65.iso constitutes Cisco’s secure guest collaboration solution for external partner communication, designed as a lightweight virtual appliance (1.2GB) for temporary access scenarios. Released in Q1 2025, this version integrates with Cisco Unified Communications Manager (CUCM) 15.5 and Webex Hybrid Services to enable GDPR/CCPA-compliant cross-organizational messaging, file sharing, and limited video conferencing capabilities.

This ISO image deploys as an OVA template supporting 500 concurrent guest sessions with automated 24-hour session expiration. It maintains FIPS 140-3 encryption for all transient data and generates audit logs compatible with Cisco Stealthwatch Enterprise v8.2+ for network behavior analysis.
