Foreword
Congratulations on the purchase of your snom 200 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 that is impossible
to ignore. In spite of the new technology base of the snom 200, most of
its look and feel will be very familiar to you and you should be able to use
it intuitively.
The world of the Internet, on the other hand, has opened up a
whole range of new possibilities. Many users work with web browsers and
own one or more email accounts. These users will nd it easy to manage
the phone via its web interface or to make a call to, for example, “sip:
[email protected]”.
We are con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
exibility, snom’s commitment to all open and relevant standards and
our cooperation with other vendors in the VoIP industry, the snom 200
represents a safe investment for the future.
We would like to take this opportunity to wish you a great time
in the world of VoIP.

§ An external power supply (48 V)
§ Power feeding over the network cable. Depending on the
model, the following is supported: snom200A (Ethernet sockets at the

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 the behavior or induce noise.
Setting up the Phone
The snom 200 should only be placed on even, horizontal surfaces
that enable the rubber pads to ensure a secure grip. Do not place the
snom 200 on carpets or other materials that contain bers that could
block the air vents and cause overheating.
Cleaning
To clean the snom 200 use an anti-static cloth. Please avoid
cleaning liquids as they might damage the surface or internal electronics
of the phone.
Connecting the phone
First connect one end of the handset cable to the handset and
then to the jack on the left-hand side of the phone (see illustration).
Next plug the Ethernet (network) cable into the RJ45 connector,
which is named “NET” or “S0” and is the nearest to the middle of the
phone (as shown below), and plug the other end into the network side
to establish a data link. The second RJ45 connector at the edge of the
phone named “PC” or “UP0“ is for daisy-chaining further Ethernet devices
without the need for a second Ethernet connection line.
If you are using an external power supply, insert the plug of the
power supply into the connector next to the data line and hook up the
casing into the mains.
If you want to use a headset, it can be connected to the audio
jacks on the rear side of the snom 200. The connector named “in“ is for
the microphone.

Keypad
The numeric keypad with the keys 0 to 9, * and # is used to enter
digits and letters. Depending on the operating mode, different actions can
be performed (see the table below):
§ Entry of digits only (e.g. when dialing a phone number),
Type in letters and digits by pressing the keys repeatedly (similar
to a cellular phone).
The key is used to invoke the menu. To cancel actions or
input, the CANCEL key can be used. The key conrms actions,
selections and inputs.
Depending on the operating mode, the keys can have context-
specic meanings and are described in this user manual.
Softkeys F1 to F3 are context-sensitive function keys. Their
current mapping is depicted in the bottom line on the display through
texts.

If the phone does not reach this operation mode and also fails
to reach the logon mode (see below), you should consult your network
administrator or Internet service provider or refer to the “Administrator
Manual”.
Selecting the language
The phone will ask the administrator to select the language of the
phone the rst time it boots up.
Choose the appropriate language with the or keys. Press
to activate your selection.
DHCP Conguration
If the network supports DHCP, then on bootup option select “On“
when the menu appears:
The phone has a built-in DHCP client. It will receive an IP address
and other Network-related settings (Netmask, IP gateway, DNS server)
from the DHCP server.

If, on the other hand, DHCP is not used, select “Off“ in the menu
above. The administrator will subsequently be asked for the following
settings.
Selecting the IP Address
The administrator can provide a static IP address for the phone
if DHCP is not used.
A valid IP address appropriate to the network in which the phone
is being used can be provided.
Selecting the Netmask
Similarly, the administrator will be asked to provide IP addresses
for Netmask:
Selecting the IP Gateway
If a valid Netmask has been provided, the administrator will be
asked for the IP address of the IP gateway:

Selecting the Tone Scheme
The administrator will then be asked for the tone scheme to be
used on the phone:
Selecting the Timezone
The timezone to be used on the phone can also be selected by
moving through the different timezone options available in the menu and

Logging on the rst account
If no number is assigned to the phone, you will be prompted to
type in your account name. This consists of your phone number succeeded
by @ and the address of your registrar (for SIP) or gatekeeper (H.323).
The phone tries to guess the correct registrar/gatekeeper address, so it
could look something like this:
After typing in your account name, conrm your account by
pressing the key.
The phone tries to register your given account name at the given
registrar/gatekeeper. The idle screen is shown and if no “NR“ is displayed
in the middle of the rst line, your registration has been successful.
When this state has been reached, the time and date are
displayed in the rst line of the display.

Logon
Mobility
In ofce environments, different employees sometimes share
desktops at the same time or at different points in time (e.g. employees
working different shifts etc). The phones that are located at the desktops
need to be able to cater for this.
To ease the effort of assigning the appropriate phone number to
the phone for each different employee, the snom200 offers the so-called
mobility features, which are described in the next sub-chapters.
Logon wizard
If no number is assigned to the phone, you will be prompted to
type in your account name. This consists of your phone number succeeded
by @ and the address of your registrar (for SIP) or gatekeeper (H.323).
The phone tries to guess the correct registrar/gatekeeper address, so it
could look something like this:
After typing in your account name, conrm your account by
pressing the key.
The phone tries to register your given account name at the given

And activate the chosen registration line by pressing “Activate”.
By choosing a different registration 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 this current outgoing line information. The
current outgoing line is marked at the registrations screen with a “*”
directly in front of the registered SIP line.
DND
DND functionality is available on the idle screen of the snom200
phone. DND is short for “Do Not Disturb“. If this mode is activated, it
means that incoming calls will no longer come through to the phone and
you will be completely undisturbed by the phone. If there is a mailbox set
up for you, the calls are redirected to this. Before this mode is activated
you will be asked if you really want to change to this mode.
