Foreword
Congratulations on the purchase of your snom 320 Voice over IP
telephone!
Telephony is part of our everyday life. Over a period of more than
100 years, a form of communication has evolved which we feel cannot be
ignored. In spite of the new technology base of the snom 320, most of its
look and feel will be very familiar to you and you should be able to use it
intuitively.
On the other hand, the world of the Internet has opened a whole
range of new possibilities. Many users are using web browsers and own
one or more e-mail accounts. They will fi nd it easy to manage the phone
via its web interface or to make a call to “sip:john@domain.de”, for
example.
We are confi dent that developments in the computer industry will
follow those in the telecom world.
VoIP is not only about transporting speech over data networks.
It is about interoperability and breaking up a vertical market, as well as
streamlining business processes by seamlessly integrating the telephone
into computer networks and applications. With its technical fl exibility,
our commitment to all open and relevant standards and our cooperation
with other vendors in the VoIP industry, the snom 320 represents a safe
investment for the future.
We would like to take this opportunity to wish you a great
experience in the VoIP world.

Delivery Content
Please check whether the delivery contains the following parts:
The base unit with display and keypad
The handset
The handset cable
The power supply (optional)
Safety Information
1
Please read the following safety notices before installing or using
your snom phone. They are crucial for the safe and reliable operation of
the device.
Power supply
You have two options for providing the snom 320 with power:
- An external power supply (5 V)
- Power feeding over the network cable (IEEE 802.3af
compatible)
If you want to use an external power supply, use the one that is
included in the package. Other power supplies may cause damage to the
phone, affect its behavior or induce noise.

Setting up the Phone
Your snom 320 is delivered with the footstand attached to the
phone’s bottom shell (shaded gray in Fig. 1). Place the snom 320 on an
even, horizontal surface that gives the rubber pads a secure grip. Do not
place it on carpets or other materials containing fi bers that could block the
air vents and cause overheating.
After connecting the phone (see chapter Connecting the Phone,
below), clip the cords into the appropriate slots on the footstand or, in the
case of the handset cord, on the bottom shell of the phone (Fig. 2).
Fig. 1 Fig. 2
Wall Mounting
It is also possible to mount the snom 320 on the wall. In order to do this,
detach the footstand from the bottom shell and attach it in the appropriate
position for wall mounting, as described in steps 1 through 6, below.
(1) Turn the phone upside down (Fig. 3). Please ensure that you do not
damage the display and/or its hinge and that you do not drop the receiver. You
may want to hold the phone in your lap or have a second person hold it.
10 • Installation
[ SNOM 320 MANUAL V1.00 ]
Fig. 3 Fig. 4
(2) Lightly press the snap-fi ts of the footstand inwards (Fig. 3)
and, at the same time, tilt the footstand backward and lift it from its
anchorage in the mounting holes (Fig. 4).
1
(3) Rotate the footstand 180° around its vertical axis.
(4) Make sure that the handset cord has been clipped correctly
into the groove on the bottom shell of the phone, as shown in Figs. 4 and
6. Failure to clip the cord into the groove will result in damage to the cord
when the footstand is attached in the position for wall mounting.
(5) Insert the outside, rear snap-fi ts into the mounting holes on
the bottom shell (Fig 5, arrow no. 1). Tilt the footstand forward and
downward until the snap-fi ts snap into place in the mounting holes.
Please make sure that the four snap-fi ts have securely snapped
into the holes before mounting the phone on the wall.

[ SNOM 320 MANUAL V1.00 ]
Fig. 5 Fig. 6
(6) The slots on the footstand for the various cords can also be
used when the phone is mounted on a wall. After connecting the phone
(see chapter Setting up the Phone, above), form the cords into loops and
gently press the long ends into the slots on the footstand (Fig. 6). If the
loops are too big they will hamper the secure mounting of the phone on
the wall; if they are too small they might bend or break the cords.
The delivery includes a template to be used for marking the
position of the holes to be drilled in the wall.
(Use wall plugs, if necessary, and screws with half-round head
profi les (diameters of screws dmax= 4.5 mm (0.1755”), diameters of
heads dmax=8.5 mm (0.3315”).
The screws must protrude approx. 0.5 cm (0.195”) from the wall
for easy wall mounting of the phone.
Adjusting the Handset Rest
The speaker of the handset has a small, rectangular indentation
that fi ts over the rounded end of the plastic tab inserted into a slot on
the top shell of the phone. When the phone is mounted on the wall, the
12 • Installation
[ SNOM 320 MANUAL V1.00 ]
handset must be placed on this rounded end to ensure that it will not fall
off.
Slide the tab out of the slot, as shown in Fig. 7, rotate it 180°,
and slide it back into the slot, as shown in Fig. 8.
Fig. 7 Fig. 8

Adjusting the Position of the Display
The position of the snom 320’s display is adjustable up to an angle of 45° (Figs.
9 and 10).
Hold down the phone with one hand and adjust the display with your other
hand. Do not use too much force and do not pull, wrench, or twist the display
as this might damage or break the hinges.

Cleaning
To clean the snom 320, use an anti-static cloth. Please avoid
cleaning liquids as they might damage the surface or the internal
electronics of the phone.

a conventional E.164 number (normal phone number) is mapped to a

Mobility
In business offi ce environments, desktops are sometimes shared
by different employees at the same time or at different points in time
(e.g., employees working different shifts, etc). The phones located on the
desktops need to be able to cater to this.
To ease the effort of assigning the appropriate phone number to
the phone for each individual employee, the snom 320 offers so-called
mobility features, which are described in the following subchapters.

If no number is assigned to the phone, you will be prompted to

“Activate”.
By choosing a different line, your originator phone number is
changed to this line. This means that different people can start calls from
the same phone with their own originator phone number, and the called
phone will display the current outgoing line information. The current
outgoing line is marked on the registration screen with an “*” directly in
front of the registered SIP line.

To change the outgoing identity from the idle screen, use the
function key “Reg” to access the fi rst registration, then move through the
currently registered lines as described above.
Challenge/Authentication
In SIP, a user can set up authentication requirements for each
registration on the phone. The password for each account name is set up
via the web interface of the phone on the confi guration pages for Lines
1-12, index card ‘Login Information’.
If the authentication password is not set, or is set wrongly, the
account will not register on that domain and the phone will be challenged
for that line. A challenge response will ask for the correct password. This
may look like the following:
The default mode for password input is integer. You can switch
to alphanumeric input by pressing the asterisk key “*”. The password is
replaced by a series of ‘*’s to keep it hidden from prying eyes.
Repeat this procedure for all accounts with authentication. The
challenge responses are stored in the phone and will be used at reregistration or upon reboot. You can also edit this information via the
web interface.

When you are calling an IP address, the called phone or
