Voicemail Pro 5.0+, fallback can include one of the IP Offices assuming control of the voicemail server should the central
IP Office become unavailable on the network.
Normal Operation
During normal operation, voicemail
services for the Small Community
Network are provided by the
central IP Office communicating
with the voicemail server.
Fallback Control Operation
If the central IP Office becomes
unavailable to the network, control
of voicemail services for the Small
Community Network is assumed by
the fallback IP Office.
· WARNING
During the transition of voicemail control, access to voicemail may be unavailable for several minutes. Existing
voicemail calls are disconnected and new calls are routed as if voicemail is unavailable. The same applies when the
central IP Office is restored.
