​​Introduction to CiscoPagingServer_9.1.1.deb Software​​

The ​​CiscoPagingServer_9.1.1.deb​​ package represents Cisco’s advanced IP-based paging solution designed for Linux server environments. Released on March 30, 2025, this Debian build (version 9.1.1, build ID 309301) integrates with Cisco Unified Communications Manager 14.8+ to enable secure multicast paging across enterprise campuses, hospitals, and industrial facilities.

As part of Cisco’s Collaboration Flex licensing model, this server software supports SIP-based paging endpoints and legacy analog speakers through Cisco ATA 190 Series adapters. The “.deb” designation confirms its optimized deployment architecture for Ubuntu Server 22.04 LTS and derivatives.
