1. Introduction to Jabber-14.1.5.307735.apk
This 142.3 MB Android installation package delivers enterprise-grade collaboration capabilities for Cisco Jabber 14.1.5 clients on Android 8.0+ devices. Designed for organizations managing hybrid workforces, it integrates with Cisco Unified Communications Manager (CUCM) 14.1+ clusters while supporting Microsoft Intune mobile application management (MAM) policies. Released on March 25, 2025, this build implements quarterly security updates mandated by Cisco’s Product Security Incident Response Team (PSIRT).
The “14.1.5” version designation indicates a Feature-Focused Release (FFR) containing targeted security hardening and performance optimizations rather than full version upgrades. It maintains backward compatibility with Webex Hybrid Calendar services and Cisco Emergency Responder 14.x systems.
