# Overview

## Before You Begin

Before you begin a configuration session:

1. You must purchase and install the Fax feature.

2. Plan your Fax configuration (see the Fax Planning section).

3. Ensure that you have the following items to use during configuration of Fax Applications:

- A NuPoint Unified Messaging server console (video monitor and keyboard) and module, with power on

- At least two telephones for configuration testing

- Completed worksheets. (Use the blank worksheets to help you configure Fax. Instructions for completing the worksheets are contained in the Fax Planning section. The configuration procedures assume that you have completed the appropriate worksheets.)

## Configuration

Configuration of all fax applications consists of the following tasks:

1. Define a Fax group: add a group of virtual Fax channels, quantity determined by Fax feature licensing to a maximum of 6 channels.

2. Assign the Fax group to Line Groups that require Fax capabilities. Assign fax to incoming line groups (like NuPoint Voice) to allow for receipt of fax messages. Assign to outgoing line groups (Pager/Outdial) to allow for transmission of outbound fax messages. Note: Fax resources are shared among line groups. If all available lines are busy processing incoming fax messages, then no lines are available for outbound messages. In this case, the outgoing messages are queued for retry. (In the case of all lines being busy, the sender of a new incoming fax will receive an error message indicating an unsuccessful transmission.)

3. Customize an FCOS and LCOS with the Fax feature bits and limits.

4. Assign the new COS values to the mailboxes that require fax features. For outbound fax using the Fax Printer Driver application, configure mailbox Call Placement options.

This section supplies detailed instructions to perform these configuration tasks.
