Both voicemail servers are constantly synchronizing settings, callflow configurations and mailboxes during normal operation. This is done using SMTP connections between the two voicemail severs. Following resilience, the same connections are used to re-synch the servers. Following any voicemail resilience, normal operation is not resumed until SMTP synchronization has restarted.
The SMTP connections are configured through the voicemail server preferences of each server. The first entry in the server's SMTP settings () is its default SMTP server. This is the entry used for inter-voicemail server traffic for features such as resilience. This Domain and Server fields of this entry must be configured with the fully qualified domain name of voicemail server, they should not be set to local host.
