Introduction to CiscoPagingServer_11.5.1.deb

This 148MB Debian package (released Q2 2025) provides enterprise-grade IP paging capabilities for Cisco Unified Communications Manager (CUCM) v11.5+ environments. Designed for organizations requiring FIPS 140-3 compliant mass notification systems, it enables synchronized audio broadcasting across 10,000+ endpoints with <500ms latency.

The software integrates with Cisco Expressway Core v12.0+ for hybrid cloud deployments, featuring 35% faster zone synchronization compared to previous versions. It supports Ubuntu 22.04 LTS and Debian 12.x systems, requiring 4-core processors with AVX2 instruction set support.
