6. Back-Up Server Modes
6.1. Normal Operation (SRST/MITEL) Disabled
Guardian Normal Backup Process:
If the primary server fails, the phone will attempt to register automatically with backup #2, if that fails, it will try with
backup #3. It will cycle through the servers until it registers or it will remain unregistered (if all servers off-
line). Once the phone establishes a link to the back up, it will remain on that server until a forced reset occurs or
the server it is on, kicks it out (reset or unregistration). Then the phone will re-attempt registration starting with the
primary server.
For all the above at anytime for any of the above, occurs and phone is not registered within 60 seconds of drop and
if the event mode is enabled for heartbeat, the phone will issue out a XML notification.
6.2. Cisco SRST
Cisco Unified SRST functions in the remote-location router to automatically detect a failure in the network and
initiate a process to provide call-processing backup redundancy for the IP phones in that location and help ensure
that the telephony capabilities stay operational. Upon restoration of WAN connectivity, the system intelligently and
automatically shifts call processing back to the primary Cisco Unified Communications Manager cluster.
