# Planning for Networked Voice Mail

Consider the following information when planning the implementation of the Networked Voice Mail feature to ensure maximum performance.

## Network Bandwidth

Your LAN/WAN must provide sufficient bandwidth to accommodate the messaging load for incoming and outgoing VPIM messages.

## Performance

### Traffic Rate

You can estimate the Networked Voice Mail traffic rate as follows:

NVM cph = S [(N - n) ´ n ´ m] , where
N

NVM cph = Networked Voice Mail messages per hour

N = number of users in entire network

n = number of users in local switch

m = number of times per hour a user sends a message directly to a mailbox

For example, in a network of 4 nodes, each supporting 500 users, and assuming each user sends 2 messages per day, the traffic rate can be estimated as:

NVM cph = 4 ´ [(4 ´ 500) - 500] ´ 500 ´ (2 ¸ 24) = 125
4 x 500

### Sending Performance

Networked Voice Mail throughput depends on a number of factors, including:

- network type

- available bandwidth

- available CPU cycles

- network traffic
