configuration settings on the backup voicemail server
are synchronized with those on the central voicemail
server. The configuration settings that are
synchronized include the registry settings, user
variables, SMTP mappings, and alarms. However, the
directory locations, settings specific to Voicemail Pro
client, Voicemail Pro IIS port settings, Campaign
settings, Service SID of the Voicemail Pro service, and
backup configuration settings are not synchronized.

server remains the message store.

configuration settings on the central server are
synchronized with those on the backup server.
· The central server sends a signal to the backup server
to indicate that it is ready to resume control as the
active voicemail server.
· Depending on the mode of failback operation
configured, the system administrator or the backup
server initiates failback operation to reinstate the
central server as the active voicemail server.
· Manual Failback
· Graceful Failback
· Automatic Failback
· Call flows defined on the central server are synchronized with the backup server.
· Call flows defined on the central server cannot be modified on the backup server.
