Configuring CUCME-Based SRST
This video builds on the previous video (CIPT2 Lab 3- Providing Redundancy with SRST and MGCP Fallback), by showing how to make a Cisco Unified Communications Manager Express (CUCME) router act as an SRST gateway. In this scenario, during normal operation Cisco IP Phones at a remote site register across an IP WAN with a centralized Cisco Unified Communications Manager (CUCM) cluster. However, if the WAN goes down, those phones register with their local SRST router, which just happens to be a CUCME router. The benefit is that those phones get an enhanced feature set in fallback mode, as opposed to using standard SRST, thanks to CUCME.
