A Small Community Network (SCN) consists of several IP Office telephone systems. Within an SCN, the following options are supported for providing voicemail:
Method |
Description |
Centralized Voicemail Server |
A single voicemail server linked to one of the IP Office systems in the network provides voicemail services for all the IP Office systems. |
Fallback IP Office |
If the IP Office linked to the centralized voicemail server fails, another IP Office system in the network can be configured to take control of the voicemail server. |
Backup Voicemail Server |
Another voicemail server can be setup as an inactive backup server. If the centralized voicemail server fails, the backup server becomes active and provides voicemail services for the network. |
Distributed Voicemail |
Multiple voicemail server can be configured, each providing voicemail services, except message storage, for various IP Office systems in the network. However the centralized voicemail server continues |
Combinations of the solutions above can be deployed. For example using a backup server and fallback IP Office control.
In all cases:
The central Voicemail Pro server remains the store for messages and recordings (except for Exchange UMS users). It also does all message waiting indication and is the server used for message collection.
Only when the centralized server is unavailable will any backup or distributed server do message storage and collection.
When the centralized server is restored, messages and recordings collected by the other servers are forwarded to the centralized server.
