# Fax server

The server-based fax service integrated on the applications card converts incoming messages into PDF files and sends them to the recipient as an e-mail attachment. When outgoing PDF files in e-mail attachments are converted into fax messages. This section deals only with the configuration of the fax server. To configure the entire fax service, you need additional configuration steps.

## Routing of incoming fax messages

DDI numbers for receiving external fax messages are monitored directly by the fax server and are not linked with a call distribution element. The fax server converts fax messages of the type Group 3 fax into an e-mail with attachment and sends it to the destination user. Use of the fax service is subject to fax licences.

Table 1. Fax server settings
Parameter | Explanation
--- | ---
IP address and port (display only) | The fax service IP address is identical to the applications card IP address. The permanently assigned port is port 9060.
Domain name | The standard domain name is fax.local. Please do not modify this if possible, after installing the fax client application on the PCs. However, if necessary, you must adapt the registry as follows on each PC: Start the fax client setup, with the following parameter request, whereby you must replace fax.local with the new domain name: Aastra-Fax-Client-Setup32.exe /v“REG_ADDREXTFAXPREFIX=\”[SMTP:\” REG_ADDREXTFAXPOSTFIX=\”@fax.local]\”” Check the registry input. This should be as follows, with the new domain name in place of fax.local: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Ferrari\fomclient\Outlook\Addin] "AddrExtFaxPostfix"="@fax.local"
Fax header | Enter the header here that should appear on the fax.
E-mail address to which error messages should be sent | Enter here the e-mail address to which the fax server should send error messages.
Exchange access prefix | Lets you specify by selecting a prefix how an external outgoing fax message should access the exchange: Enter the usual exchange access prefix according to the numbering plan (country-specific default value): The prefix is added to the destination number and the routing takes place via the transit route (in the default setting this is route1). The user or user application dials the destination number without an access prefix and not in canonical format. Example: Prefix “0” is the default value for most European countries. You enter a route prefix: The prefix is added to the destination number and the routing takes place via the corresponding route. The user or user application dials the destination number without an access prefix and not in canonical format. Example: Prefix “173” is the default route selection for route 4. You leave the field blank: No prefix is made to precede the destination number. The user or user application dials the destination number with an access prefix or in canonical format. The routing takes place in accordance with the selected destination number.
Maximum internal number length | Enter here the maximum length of the internal call number. The fax service will then handle as external call numbers any destination number that has more characters than those entered here and, in accordance with the Prefix for dial-up access setting, will prefix them with an exchange access prefix. A destination number with fewer or just as many digits as those entered here will be handled as an internal call number: The fax server checks whether a fax DDI number exists for the destination user. If it does, the fax message is converted and sent to the internal user with an e-mail. If not, the fax message is put through as an ordinary call and the user will obtain the fax transmission tones when he picks up.

## Creating and managing fax cover pages

You want to provide outgoing fax messages with a cover page.

You have the possibility of uploading and using up to five cover pages. The cover pages must be available in RTF format; they may also contain images. Make sure however that the images are low resolution. Do not use colours when creating the cover page as fax messages are always transmitted in black and white.

- To upload a cover image, click the Browse button.

- To download a cover page from the communication server to your PC, click the Download hyperlink.

- To give a cover image a name, enter the name of your choice in the input field of the second column.

Use the following placeholders to represent specific information.

## Instructions on how to set up the fax service on the communication server

You can only set up the fax service in expert mode.

To set up the fax service on the communication server via a digital network interface (ISDN/CAS or SIP), proceed as follows:

1. Set up the fax server in the current view and upload the cover pages you want to use.

2. If you are not yet in expert mode, change to expert mode now.

3. Create the DDI numbers for receiving fax messages and assign the fax server as their routing destination (Configuration / Routing / DDI numbers view, Routing destination = Fax server setting).

4. Check that the settings for the DDI interpretation are correct (Configuration / Routing / Trunk group view, Base number setting and DDI prefix setting).

5. Check the user settings to make sure an e-mail address is entered for all the intended destination users (Configuration / User view).

6. Select a fax number for each intended destination user and assign each of them the cover sheet you want (Multimedia section, Fax mailbox / Fax number setting and Cover sheet setting).

7. Check the terminal settings of the connected Group 3 fax devices to make sure the Fax device setting is set to a value other than No fax device (Configuration / Terminals view).

8. Set up the SMTP server (Configuration / IP network / Routing view) and ask your IT manager to set up an SMTP connector for the Exchange Server and to enter the fax domain in the Exchange Server.

9. Install the fax client application on the fax users' PCs. To do so, open the Configuration / Multimedia / Client rollout view, send the installation link or start the installation directly if you are working from the destination computer.

To set up the fax service on the communication server via an analogue network interface, proceed as follows:

1. Follow the above instructions step by step 2.

2. Assign the fax server as routing destination for the fax trunk group (Configuration / Call routing / Trunk group view, Routing destination = Fax server setting).

3. Enter as base number the entire external call numbers of the fax extension in canonical format (Configuration / Call routing / Trunk group view, Base number setting).

4. In the fax recipient's user settings, select the set fax number and assign the user a cover sheet (Multimedia section, Fax mailbox / Fax number setting and Cover sheet setting).

5. Check whether an e-mail address has been entered (Configuration / User view).

6. Continue with step 7 of the above instruction.
