Safety Notes
!
Power supply
Please observe the following safety
advice. It is important to observe it in
order guarantee safe and reliable
operation of the device.
You have two possibilities to provide the snom 100
with power:
� Power feeding over the network cable
(PowerLAN)
� An external power supply
If you want to use an external power supply then
please only use the supplied part. Other power
supplies may cause damage to the phone, effect the
behavior or induce noise.
Setting up the Phone
Please setup the snom 100 only on even and
horizontal surfaces, enabling the rubber pads to
ensure a secure placement. Do not place the snom
100 on carpets or other materials that contain fibers
that can block the air vents and cause overheating.
6

Cleaning
To clean the snom 100 use a slightly moist and
antistatic cloth. Please try to avoid cleaning liquids
since they might damage the surface or internal
electronics of the phone.
Connecting the phone
First connect one end of the handset cable to handset
and then to the jack on the left side of the phone (see
illustration).
Now, plug in the Ethernet (network) cable into the
RJ45 connector on the rear side of the phone as
shown below and the other end into the network side
to establish a data link.
In case you are using an external power supply,
please insert the plug of the power supply into the
connector next to the data line and hook up the casing
into the mains.
7

If you want to use a headset, it can be connected to
the audio jacks on the backside of the snom 100. The
outermost connector is for the microphone.
Dial Pad
The numeric key block with the keys 0 to 9, * and #
are 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),
� Typing in letters and digits by pressing the
keys repeatedly similar to a cellular phone,
� Or navigate in selection lists. The keys have
arrows printed on them indicating the
direction similar to a numeric block on a
computer keyboard.
The various meaning of the keys in different
operations modes is displayed in the lower right hand
8

corner with a symbol. A “123” indicates the numeric,
“abc” the lower case and “ABC” the upper case mode.
The function keys F1 to F4 are context sensitive, i.e.
they change their behavior according to the mode of
the phone.
The menu key is used to call up the main menu.
Context help texts can be activated with the help key
. The Cancel is used to abort actions or cancel
inputs. The Enter/Ok key confirms actions,
selections and inputs.

Initialization
Booting
If your network administrator or Internet service
provider prepared your phone, you will see how the
phone connects up to the network and maybe
conducts a software update. After it has booted it
enters the normal operation mode. When this state
has been reached a clock is displayed on the right
hand side of the display.
In case the phone does not reach the operation mode
you should consult your network administrator or
Internet service provider or refer to the chapter
“Administration”.

Selecting the language
The language is set to English by default. In, order to
change it for instance to German, press the menu key
and go to the submenu „Settings“ with or
and press Enter to select this menu entry.
Select „Base“ and press Enter.
Then go to „Language“
and set it to „Deutsch“.
11

Press Enter to activate your selection.
Registration
In order to be able to make calls, the phone normally
has to register with „Gatekeeper“ (H.323) or a
„Registrar“ (SIP). You can obtain the Internet address
or name of the server from your network
administrator or Internet service provider. The
registration is similar to the configuration of an email
address:
TIP
VoIP has two competing signaling standards to
establish and tear down calls. „H.323“ is based
on a telecom protocols and is the older
standard. „SIP“ (Session Initiation Protocol) is
based on Internet standards and is similar to
Email and WWW. The snom 100 supports both
protocols. Please ask your company or
Internet service provider which protocol you
are using.
12

Most of the Gatekeeper can be found automatically by
the snom 100. Thus, you only need to enter your
phone number. Go to the menu Settings/Base/Identity
and set the phone number.
� If you want to set the gatekeeper address
then go to the “Settings” menu (as described
above) and then to „H.323“. Select „GK/GW-
Address“ and type in the address.
13

� When using the phone in a SIP environment,
go to the sub menu „Settings/SIP/Registrar“
and set the address of the registrar (e.g.
proxy.sipproxy.com). Also program the
address of the SIP proxy. Normally, this will
be identical to the address of the registrar.
14

Basic Functions
17

Idle State
In the idle state the phone will display
� The time and date,
� The number of dialed, received and missed
calls,
� The registration state
Continuous lines under the registration symbol
indicate a successful registration with the specified
gatekeeper or registrar. Dashed lines (see example)
signal that the phone is not registered, i.e. it did not
get a reply. An exclamation mark denotes that the
registration was denied.
Dialing
There are two methods to begin a call from the idle
state snom 100. Either you can start dialing with
handset resting in the cradle and then pick it up. Or
pick up the handset and then dial the number.
You might have to press Enter if block dialing is
enabled (see “Settings”).
18

The snom 100 shows the current communication
status in the display.
Dialing a phone number (E164)
A telephone number in the common sense is dialed as
one expect with the numeric pad.
TIP
E.164 numbers
E.164 is the standard that define normal
phone numbers. They may contain digits
from 0-9, * and #. H.323 differentiates
between these numbers and “H.323
addresses“ which may contain alphanumeric
characters. Several Gatekeeper
implementations do not differentiate E.164
numbers and H.323 addresses. In case you
encounter problems then try to specify the
number as a H.323 address.

Terminating a call
You can end a call by setting the handset on its cradle,
pressing the hook switch or Cancel. The snom 100 will
terminate the call and return to the idle state.
TIP
Dialing an IP Address
When calling an IP address the called phone
or computer cannot determine which user
you want to reach. In SIP mode it is
assumed that „anonymous“ is being called
and with H.323 no assumptions are made.
This works with a lot of phones and
applications. Therefore, you should only use
this method in exceptions and in addition
the entry of IP addresses is rather
cumbersome.

Advanced
Ring Tone
The ring tone is the alerting signal when an incoming
call is detected. Here the ring tone of the phone can
be turned on or off (the phone is mute) or it only
responds to certain callers (see the VIP flag in the
phone book chapter). Press the menu key in the idle
state and select the submenu “Settings / Advanced /
Ring Tone”:
� All: all incoming calls are signaled.
� Off: no incoming call is signaled.
Call Waiting

additional call, which is waiting to be accepted. You
will hear the other party you are calling but
additionally you can hear a “knocking sound”. You can
now decide whether to interrupt the current call and
to accept the waiting call or reject it. The calling party
receives an alerting tone as long as he is not rejected.
Press the menu key in the idle state and select the
submenu “Settings / Advanced / Call Waiting”:
� Off: „Call Waiting“ is disabled.
� On: „Call Waiting“ is enabled.
Silence Suppression
Silence suppression is use in order to save bandwidth
on the network between speech pauses. Nothing
needs to be transmitted while no words are being
exchanged. The other end will not hear anything
during a speech pause not even background noises.
Press the menu key in the idle state and select the
submenu “Settings / Advanced / Silence Suppression”:
� Off: data is transmitted during speech pauses.
� On: data is NOT transmitted during speech
pauses.
48

Comfort Noise
If you have „Silence Suppression“ enabled then no
data is transmitted during speech pauses. The other
party will normally not hear anything in this moment.
This absolute silence is unusual for a user and it may
lead him to believe that the line is interrupted or that
the phone is dysfunctional. To give him an audio
feedback you can activate “Comfort Noise”. The phone
will then generate a background noise when it does
not receive any audio data.
Press the menu key in the idle state and select the
submenu “Settings / Advanced / Comfort Noise”:
� Off: no background noise is generated during
speech pauses.
� On: background noise is generated during
speech pauses.

dialed is transferred immediately. In the block-dialing
mode the digits are collected and not sent until Enter
is pressed or the handset is picked up. This pertains
only to E.164 numbers.
Press the menu key in the idle state and select the
submenu “Settings / Advanced / Block Dialing”:
� On: the digits are not sent until Enter is
pressed or the handset is picked up.
� Off: every digit is transferred immediately.
Network
PSTN Gateway
The identification of a destination in an IP network is
done by an IP address. In a telecom network
destinations are referenced through phone numbers.
In order for the VoIP phone to address destinations in
a telecom network a PSTN gateway is needed. Here
the IP address of your gateway can be entered (e.g.
192.168.0.251).
49

Press the menu key in the idle state and select the
submenu “Settings / Network / PSTN Gateway”.
Priority
When speech and data is transmitted in one network,
it makes sense to give speech priority over data to
ensure good voice quality. You can set the priority of
the speech data on your phone. Please ask your
network administrator which value should be set.
Press the menu key in the idle state and select the
submenu “Settings / Network / Priority”.
Packet Size
The VoIP phone converts speech to digital values that
are grouped into the payload of IP packets. Please ask
your system administrator which value should be set
within your network.
Press the menu key in the idle state and select the
submenu “Settings / Network / Packet Size”.
IP Proxy Address
Here the IP Address of the Proxy can be set. Please
ask your system administrator which value should be
set within your network.
Press the menu key in the idle state and select the
submenu “Settings / Network / IP Proxy Address”.
IP Port Offset
Here the IP Port Offset of the Proxy can be set. Please
ask your system administrator which value should be
set within your network.
Press the menu key in the idle state and select the
submenu “Settings / Network / IP Port Offset”.
H.323
GK-GW Mode
The VoIP phone can be used with a gatekeeper,
gateway or without them. Please ask your system
50

administrator which value should be set within your
network.
Press the menu key in the idle state and select the
submenu “Settings / Network / GK-GW Mode”:
� Gatekeeper: The phone is in gatekeeper
mode. Set the IP address of the gatekeeper in
“Settings / Network / GK-GW Address”.
� None: The phone is used without a gatekeeper
and without a gateway.
� Auto: The phone is in gatekeeper mode but it
uses a multicast to automatically detect it.
� Gateway: The phone is in gateway mode. Set
the IP address of the gateway in “Settings /
H.323 / GK-GW Address”.
GK-GW Address
Whether the phone is set to gatekeeper or gateway
mode (see "GK-GW Mode") here the IP address is set.
Press the menu key in the idle state and select the
submenu “Settings / H.323 / GK-GW Address”.
Fast Connect
When setting up a call H.323 normally first sets up the
connection and then begins to negotiate the codecs.
With terminals a long way apart the beginning of the
call could be lost. In order to avoid this “Fast Start”
was invented, i.e. the codecs supported are sent
immediately so no further time after the call
established is lost. Unfortunately, some terminals
cannot handle fast start correctly. While normally this
parameter should be set to “on”, it should be set to
“off” if you encounter problems to setup a connection.
Press the menu key in the idle state and select the
submenu “Settings / H.323 / Fast Start”.
� On: „Fast Start“ is enabled.
� Off: „Fast Start“ is disabled.
51

Administration
54

!
This chapter is meant for people that
want to install the phone in a VoIP
network. It has to be ensured that the
necessary rights and skills exist to
perform this task.
Flash Updates
The snom 100 possesses an internal flash memory in
which necessary information and programs are stored
for the phones operation. The flash is divided into
three parts:
� Boot loader: This section boots the phone and
searches for flash updates. This sector should
never be written.
� Operating and File System: here the Linux and
the initial ram disk is located.
� Settings: in this section the settings are
saved.
In order to make flash updates as easy as possible
and to increase the reliability of the phones, they test
whether the network provides a new image.
Via a BOOTP broadcast the snom 100 tries to
determine a TFTP server. On this server first the file
with the name „snom100-xx-xx-xx.bin“ and then the
file „snom100.bin“ is searched. Whereby the xx-xx-xx
represents the last the bytes of the MAC address. In
case the BOOTP server specifies a filename then this is
checked first!
TIP
Testing a flash update
If you want to determine whether a flash
update makes sense then you should select
one or a few phones on which you want to
try out the update. Copy the file to be
updated onto the TFTP server from which
the phones will retrieve the file. Save the
image with the filename snom100-xx-xxxx.bin
whereby xx-xx-xx represents the last
three bytes of the MAC address of the test
phones.
55

� If no BOOTP server responds then the TFTP
server is contacted that was specified in the
phone settings (see below).
� If no file is found within a certain time then
the image in the flash is booted.
� If the TFTP server responds and sends a file
then it is downloaded and compared with the
flash image. If they differ then the flash is
updated.
After the update, the image is booted.
Setting the Network Identity
The phone needs to have a network identity to be able
to communicate. These values are the IP address and
the network mask. A few other base settings are
needed to make easy and comfortable configuring of
the phone over network possible. There are basically
two methods to set the basic settings:
� DHCP (Dynamic Host Configuration Protocol).
With this protocol a server provides the
settings and local settings of the phone are
overridden.
� Phone Configuration. Here the settings are
entered via the dial pad and stored in the
flash.
DHCP is the better choice if a network of phones
should be centrally configured. This is especially useful
for bigger networks in which a large number of phones
can be managed efficiently. Manual configuration
should only be used in smaller networks where the
setting up of a DHCP server is too cumbersome.
Installing DHCP
Windows 2000
Ensure that you have installed DHCP on the server.
You can verify this by going to Start, Configuration,
System Settings, Administration, Server
56

Configuration, Network, DHCP and follow the
instructions of the wizard. Invoke the DHCP manager.
The snom 100 behaves like a normal PC running
under Linux. Most of the DHCP parameters can thus
be set, as this would be normally done. The vendor
specific options in the DHCP option field 43 are set in
an ASCII string that contains the format
Option1=Value1:Option2=Value2: etc (This string can
be edited comfortably when clicking on to the ASCII
field on the right side). Please ensure that your input
starts with the first character on the left.
57

The following options have an influence on the snom
100:
Option Typical Value
002 Time Offset 7200
003 Router 192.168.0.1
004 Time Server 192.168.0.9
005 Name Server 192.168.0.9
006 DNS Server 192.168.0.9, 174.129.1.129
012 Hostname Telefon123
015 DNS Domain
Name
intern.snom.de
017 Root Directory /tftpboot/disk
043 LCServer1,
LCSserver2
066 TFTP Server 192.168.0.9
067 Update Image snom100.bin
lcserver1=192.168.0.12:lcserver2=192.168.0.34
58

Make sure that BOOTP and DHCP are activated in case
you want to utilize them.
BOOTP is similar to DHCP only useful for the
administration of larger networks. It is only needed
when the administrator want to avoid setting the TFTP
addresses manually on each phone.
Windows does not offer a TFTP-Server. It has to be
obtained from another provider to make a flash
update possible on a Windows system.
59

Linux
The DCHP settings are set in the file /etc/dhcpd.conf
when using Linux (see dhcpd(8)). A sample dhcp.conf
file for three phones with the serial numbers 1, 2, 3
could look like the following:
# dhcpd.conf
option domain-name "intern.snom.de";
option domain-name-servers 192.168.0.9;
option time-offset 7200;
option time-servers 192.168.0.9;
option root-path "/tftpboot/disk";
option ntp-servers 192.168.0.9;
option tftp-server-name "192.168.0.9";
#filename "snom100.bin";
deny bootp; # BOOTP ist ausgeschaltet !
#allow bootp;
option subnet-mask 255.255.255.0;
default-lease-time 600;
max-lease-time 7200;
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.50 192.168.0.99;
option broadcast-address 192.168.0.255;
option routers 192.168.0.1;
}
host snom1 { hardware ethernet 00:04:13:00:00:01;
fixed-address snom1; }
host snom2 { hardware ethernet 00:04:13:00:00:02;
fixed-address snom2; }
host snom3 { hardware ethernet 00:04:13:00:00:03;
fixed-address snom3; }
Settings via the Phone
IF you do not have access to a DHCP server or do not
want to use one then the settings can be entered
directly into the phone.
60

Press the Cancel key as soon as you see the text
„Please press Cancel for Setup“. If the phone does not
have enough information to boot it will go to the
configuration mode automatically.
Parameters
The following parameters can be set directly on the
phone:
Factory Settings
Setting this value to „on“ can set all entries to the
factory defaults.
DHCP
This parameter determines whether DHCP is used or
not. In case you are selecting DHCP you do not need
to set the other fields since the DHCP will provide all
values – provided you have set it up correctly (see
above). Please note a flash update without BOOTP is
only possible with DHCP mode deactivated.
IP Address
This field contains the IP address of your phone.
Net mask
Here the net mask of the phone is set (e.g.
255.255.255.0). Ask your network administrator if you
are not sure how to set this value.
Phone Name
Here the phone name can be set (e.g. tel1234). The
default is snom100-xx-xx-xx.
IP Gateway
This is the gateway to which IP packets are sent if
they cannot be sent directly to the IP destination. This
field has nothing to do with H.323 gateway or SIP
proxy – these settings are found in the chapter
„Settings”.
61

LCServer 1. LCServer 2
The phones can connect to application servers that
contain the signaling stacks and GUI. There are two
entries to increase the reliability. Please use the value
127.0.0.1 if the local (no server) phone software
should be used. This parameter is very useful if
software version are needed that can debug H.323
traces which would not fit on to the phone.
By specifying a second server the reliability can be
increased significantly.
DNS Domain
The DNS domain is programmed here and used by the
resolver (e.g. snom.com).
DNS Server 1, DNS Server 2
Specify the primary and secondary DNS server in this
field (e.g. 192.168.0.9)
TFTP server
Store the IP address of the TFTP server here. The
phone can use it to save files on it and the phones
retrieve the flash updates from here.
TIP
TFTP
TFTP is a trivial file transport protocol. It is
based on UDP and has a very simple
message format. Since it is very easy to
implement a lot of hardware vendors use it
to load configuration files.
The snom 100 uses it to load flash updates
and to save settings. Ensure that the snom
100 has access to a TFTP server to utilize its
whole potential.
62

UTC Offset (s)
Indicates how many seconds the local time zone
varies from UTC (e.g. 7200). Positive values indicate a
destination east of Greenwich.
Time Server
This is the IP address of the timeserver. The phone
uses the SNTP protocol to set the time.
Boot Server
This is the server that booted the phone.
NFS Server
This is a special entry for developers that are using a
kernel that mounts NFS.
NFS Root Directory
This is the root directory that the phone should mount
via NFS (developer version only). The default value is
“/tftpboot/disk”.
Phone Type
The value of this field determines whether the snom
100 is going to use SIP or H.323. If you prefer H.323
then set the value to "snom100-H323". Selecting
„snom100-SIP“ sets SIP mode.
Usage
You can use the dial pad of the phone to modify the
settings. Digits can be entered directly by pressing the
keys and letters by doing so repeatedly. A symbol on
the lower right hand corner indicates whether digits
("0"), lower case letters ("a") or upper case letters
("A") can be entered. You can toggle these modes by
pressing * (asterisk).
63

Navigating from one parameter to the next is possible
via ("Next") and to the previous parameter via
("Prev") which are mapped onto the function keys.
The phone verifies the value of the parameter and
only allows switching after the plausibility test is
passed. To erase the last character press F3 ("|
