SRST tests use a ping, originated by an IP SLA device to the SRST gateway device.
Also, Operations Manager checks the status of the SRST phone. If the ping to the SRST
gateway fails and the SRST phone becomes unregistered to the Cisco CallManager,
Operations Manager determines the branch office to be in SRST mode.
When creating an SRST test, the IP SLA device should be a Cisco IOS device closest to
the Cisco CallManager serving that SRST remote office, preferably on the same subnet as
the Cisco CallManager. The destination router is the SRST gateway. Make sure to choose
an SRST remote office phone. You can use the IP phone report to select the phone.
