2.5 Centralized Voicemail Pro

A Small Community Network (SCN) consists of several IP Office telephone systems. These are connected using H323 Lines where the Supplementary Services settings of the lines has been set to IP Office SCN. For details refer to the IP Office Manager documentation.

Within a Small Community Network, the following options for providing voicemail are supported:

Centralized Voicemail

53

Centralized Voicemail Pro uses a single Voicemail Pro server to provide voicemail services for all IP Offices in the Small Community Network. Except for use of ContactStore, only the central IP Office hosting the voicemail server requires licensing for Voicemail Pro operation and features.

Licenses: The central IP Office is licensed as normal for Voicemail Pro operation and the voicemail features required. The other IP Offices only require licenses for UMS and or for ContactStore if required.

Centralized Voicemail with Fallback IP Office

54

Control of the voicemail server can be assumed by another IP Office if the central IP Office becomes unavailable.

IP Office Release 5.0+ with Voicemail Pro 5.0+.

Licenses: The fallback IP Office that assumes control of the voicemail server requires licenses for Voicemail Pro operation and the features required during fallback.

Centralized Voicemail with a Backup Voicemail Server

55

The central IP Office hosting the voicemail server can be configured with the IP address of a backup voicemail server. During normal operation, call flows and other settings on the backup server are kept synchronized with those of the primary voicemail server. If the primary voicemail server becomes unavailable to the network, voicemail services are provided by the backup voicemail server.

IP Office Release 6.0+ with Voicemail Pro 6.0+. IIS SMTP is used to exchange information between the servers.

Licenses: The existing licenses are used.

Centralized Voicemail with Distributed Voicemail

Servers

56

Other IP Offices in the Small Community Network can host their own Voicemail Pro server. That server is then used for the IP Office's voicemail functions except message storage.

IP Office Release 6.0+ with Voicemail Pro 6.0+. IIS SMTP is used to exchange information between the servers.

The distributed voicemail server provides all voicemail services except voicemail collection for its associated IP Office.

Licenses: Each IP Office using a distributed voicemail server must have licenses for Voicemail Pro operation and the voicemail features required.

In all the cases above, the central voicemail server remains the store for messages and recordings (except for Exchange UMS users). The central voicemail server does message waiting indication and is the voicemail server used for message collection. Only when the central server is temporarily unavailable will the backup or any distributed server do message storage and collection. In those scenarios, when the central server is restored, messages collected by the backup or distributed servers are forwarded to the central server.

Combinations control.
