# Network Configurations

Networked Voice Mail supports the following network configurations:

- Distributed embedded voice mail servers.

- Centralized voice mail servers.

## Conditions

- The WAN/LAN must have adequate bandwidth to support Networked Voice Mail (see Planning for Networked Voice Mail).

## Distributed Voice Mail Configuration

In a distributed voice mail configuration, each node has its own embedded voice mail server. This means that:

- Each voice mail node has a different hunt group number.

- Each voice mail node has its own Auto Attendant.

- When calling from outside the network: to access a mailbox that is not on the same node as the main number, users must first transfer to the Auto Attendant of the desired node by entering its hunt group number.

- For resilient users, the users' voice mail server must be on their extension's primary ICP.

### Example

In this example, the 3300 ICPs are in a cluster, with a PNI of 560.

Networked Voice Mail Users Configuration form data for Box1:

PNI | Mailbox Number | Name | Extension Number | Mailbox Type | VM Server Name* | Backup VM Server Name* | Local
560 | 1001 | User1 | 1001 | Extension | Box1 | Box2 | True
560 | 1002 | User2 | 1002 | Extension | Box1 | Box2 | True
560 | 2001 | User3 | 2001 | Extension | Box2 | Box3 | False
560 | 2002 | User4 | 2002 | Extension | Box2 | Box3 | False
560 | 3001 | User5 | 3001 | Extension | Box3 | Box1 | False
560 | 3002 | User6 | 3002 | Extension | Box3 | Box1 | False

* Must match the "System Name" field in each server's System Options form.

Required Networked Voice Mail Servers form data for Box1:

Element Name* | Element Type | Local | Cluster | PNI
Box1 | 3300 ICP | True | True | 560
Box2 | 3300 ICP | False | True | 560
Box3 | 3300 ICP | False | True | 560

* Must match the "System Name" field in each server's System Options form.

The following fields are not shown:

- IP Address

- DNS Name

- Time Zone

- Comment

## Centralized (Clustered) Voice Mail Configuration

In a centralized voice mail configuration, one or more nodes serve as central voice mail servers. This means that:

- Each ICP must be programmed to forward voice mail calls to the appropriate voice mail server trunk.

- The extension associated with the mailboxes must not match those on other ICPs.

- Users must use the telephone interface to program Forward to Email.

- The users' voice mail servers must be different from their extension's primary ICP.

NOTE: Networked Voice Mail does not apply when there is only one voice mail server (single node).

### Example

In this example, the 3300 ICPs are in a cluster, and share the same PNI.

Networked Voice Mail Users Configuration form data for Box1:

PNI | Mailbox Number | Name | Extension Number | Mailbox Type | VM Server Name* | Backup VM Server Name* | Local
560 | 5001 | User1 | 5001 | Extension | VM1 | VM2 | False
560 | 5002 | User2 | 5002 | Extension | VM1 | VM2 | False
560 | 5003 | User3 | 5003 | Extension | VM1 | VM2 | False
560 | 6001 | User4 | 6001 | Extension | VM2 | VM1 | False
560 | 6002 | User5 | 6002 | Extension | VM2 | VM1 | False
560 | 6003 | User6 | 6003 | Extension | VM2 | VM1 | False

* Must match the "System Name" field in each server's System Options form.

Required Networked Voice Mail Servers form data for Box1:

Element Name* | Element Type | Local | Cluster | PNI
VM1 | 3300 ICP | False | True | 560
| 3300 ICP | False | True | 560

* Must match the "System Name" field in each server's System Options form.
