Introduction to Cisco UC OS Installations Upgrading or recovering a Cisco Unified Communications (UC) application requires a highly specific installer image. The file is a bootable ISO image used for fresh installations, bare-metal deployments, and disaster recovery. It specifically targets Cisco Unified Communications Operating System (UCOS) products, including Cisco Unified Communications Manager (CUCM), Cisco Unity Connection, and Cisco Unified Contact Center Express (UCCX).
