The capability to use centralized call-processing devices that are located at remote sites depends on the availability of Cisco Unified Communications Manager (CUCM) at the main site. To provide these devices with a backup, you can use Media Gateway Control Protocol (MGCP) fallback and Cisco Unified Survivable Remote Site Telephony (SRST). This course describes the mechanisms for providing call survivability and device failover in remote sites. It describes how to configure Cisco IOS routers as Cisco Unified SRST gateways and how to use Cisco Unified Communications Manager Express (CUCME) in Cisco Unified SRST mode.Learning Objectives
