IP Office Preferred Edition - Voicemail Pro Resilience and Backup
Customer service with uninterrupted access to the business is essential – for customers who want to place
orders, for partners who want to negotiate an important contract and for employees who need access to their
important messages. A failure can be very expensive for a business and there are a number of reasons why a
failure can happen: power outage, lost network connection, cable cuts, hardware failure, and so on.
But loss of money and reputation does not necessarily have to follow such a failure. The IP Office Resilience and
Backup functionalities are supported by Voicemail Pro. A Voicemail Pro server, connected to a Primary IP Office,
can automatically re-connect to a Backup IP Office if the connection between the two IP Office systems gets
lost. This covers the failure of an IP Office or the connection between them. A Preferred Edition license is
required on the backup IP Office system for this scenario.
Introduced with IP Office Release 6, a Backup Voicemail Pro server offers additional comprehensive
functionalities to keep the business communication up and running. A Backup Voicemail Pro server can be
added to an IP Office / Voicemail Pro system to take over the voicemail functions in the case of a failure at the
primary Voicemail Pro system.
The Backup Voicemail Pro server can act in different scenarios:
·
One IP Office, one Primary Voicemail Pro server, and one Backup Voicemail Pro server, where the
backup is either at the same location as the IP Office / Voicemail Pro or at an external site
·
A Primary IP Office with a Primary Voicemail Pro server and a Backup IP Office with a Backup
Voicemail Pro server at a second location
·
A Multi Site Network with a Centralized Voicemail Pro server connected to an IP Office at one site and a
networked IP Office with a Backup Voicemail Pro server. There might also be additional IP Office and
Distributed VoiceMail systems within that Multi Site Network.
The diagram illustrates the second scenario:
The Primary Voicemail Pro will establish a link to the Backup Voicemail Pro and keep the greetings and
configuration setting changes synchronized with the Primary Voicemail Pro. Messages and message states are
not synchronized between the Primary and the Backup Voicemail Pro to avoid network overload.
Ideally the Backup Voicemail Pro server is a mirror system of the Primary Voicemail Pro server with all its
capabilities, like the number of ports, licensed features, and hardware. All required functions have to be
licensed through IP Office Preferred Edition and supported by adequate hardware (e.g. to ensure server
performance and sufficient IP Office trunk lines). The 2 hour run-time of a Voicemail Pro server without licenses
does not apply to a backup scenario.
The Backup Voicemail Pro server can have limited functionalities (e.g. fewer number of ports) if it is acceptable
to have limited capabilities for a limited period until the re-connection of the main server.
