UCM6xxx Series - Fax Server Guide

INTRODUCTION
Fax Server is one of the most useful and important UCM6xxx features that allows the user to send and
receive Fax files. The UCM6xxx IP-PBX series support T.30 for legacy analog Fax transmissions along with
T.38 and Pass-through for Fax Over IP. The UCM6xxx series provide a lot of options and methods to perform
sending/receiving Fax files depending on user’s resources and the way he/she wants to proceed.
UCM Fax Server supports T.38 which is a protocol that dictates how to send a fax over a computer data
network and requires a T.38-capable VoIP service or gateway (please check with your service provider for
this protocol support), otherwise the transmission of Fax will proceed via pass through using RTP for
sending facsimile signals.
This guide describes the steps to follow in order to perform sending and receiving fax files when the user
has an Analog Fax machine connected to UCM6xxx’s FXS Port or when he only wants to use a virtual fax
machine and benefit from the value-added features of the UCM6xxx related to fax.

SETUP UCM6XXX WITH PHYSICAL FAX MACHINE
FXS Extension Configuration
FXS (Foreign exchange station) is any telephone interface that is used for end-user analog telephony
equipment, (i.e. analog fax machine and analog phones) to provide battery power, dial tone and generate
the ringing voltage and therefore the user needs to create a “FXS Extension” for the Fax machine to be
used.
All the UCM IP-PBX models have two FXS ports to connect analog phone and Fax machine for typical SMB
installations.
Please, refer to the following steps in order to create the FXS extension:
1. Go to UCM6xxx Web GUI Extension/Trunk Extension.
2. Click on .
3. Under “Basic Settings”, configure the extension’s parameters.
PSTN Carrier
Internet
PSTN Line
SIP Trunk
UCM6xxx Series - Fax Server Guide

Figure 1: Create FXS Extension for Fax Machine (Basic Settings)
4. Select the extension type to be “FXS Extension” and select which FXS port where the FAX machine
will be connected.
Figure 2: Create FXS Extension for Fax Machine (Media)
5. Under “Media”, set the “Fax Mode” to “Fax Gateway” so that the UCM6xxx can support
conversation and processing of Fax data from T.30 to T.38 and T.38 to T.30.
6. Click on Save and Apply changes.
Connecting FAX Machine to UCM
After creating the FXS extension, the user needs to make sure of connecting his Fax Machine to the chosen
and configured FXS Port. The following figure shows the example of UCM6510’s FXS Ports.
UCM6xxx Series - Fax Server Guide
P a g e | 8
Figure 3: FXS Ports of UCM6510 (Example)
Routing FAX Calls
As shown on below diagram, the fax transmission originates from the physical Fax machine as a T.30 fax.
Then the built-in T.38 gateway module in UCM6xxx translates the fax transmission to T.38 format and sends
it over the IP network to the other UCM6xxx.
The second Server translates back the transmission to T.30 and sends it the attached Fax Machine or over
the PSTN line for external numbers.
User needs to setup Trunks and call routing rules in order to route incoming and outgoing fax through the
desired trunk, we will show the steps to use analog and VOIP trunk to perform sending and receiving Fax
files.
Create Analog Trunk
Please, refer to the following steps in order to create an analog trunk:
1. Go to UCM6xxx Web UI Extension/Trunk Analog trunks.
UCM6xxx Series - Fax Server Guide
P a g e | 9
2. Click on to create a new Analog Trunk, or on to edit an existing one.
Figure 4: Analog Trunk for Fax
Note:
Make sure to choose the right FXO port where PSTN Line is connected and to set Fax Mode on “none”.
3. Click on “Saveand “Apply Changes”.
Create VoIP Trunk
Please, refer to the following steps in order to create a VoIP Trunk:
1. Go to UCM6xxx Web UI Extension/Trunk VoIP Trunks.
2. Click on to create a new VoIP Trunk.
UCM6xxx Series - Fax Server Guide

3. Set the SIP credentials given by the service provider (server IP or domain, username and
password…etc).
4. Click on “Save” and “Apply Changes”.
Figure 5: VoIP Trunk
Sending/Receiving Fax Files using Fax Machine
Please, refer to the following steps in order to manage sending/receiving faxes using a fax machine.
