Welcome to snom
4S !
SIP is becoming more and more accepted in the area of VoIP.
Many companies are working on SIP solutions and making great products
that will make telephony much easier and better. However, a easy to use
and affordable SIP proxy is hard to get at the moment. But SIP telephony
without a proxy makes no sense. That is why we are making this simple
and straightforward proxy available.
snom 4S stands for “snom soft switch for small and medium
enterprises”. That means the focus of the product is on a feature-rich
and easy-to-use product. The snom 4S can be used from very small
installation with only a few phones and can be scaled beyond the needs
of medium-sized corporations. In these application areas, you will use
the local le system to permanently store the necessary context. When
employing external databases, the snom 4S proxy can be operated
independently from the number of users. This is typically the case in
operator environments.
This product is a Registrar/Proxy which means this software is
responsible for locating users. Features like Follow me and group calling
are therefore supported; however media services like mailbox and music
on hold are not part of the software. You should use a media server for
this.
Interoperability is important to us. We have tried to stick to the
SIP standard as well as possible and tested the phones of other vendors.
We hope that this will help to build up a ourishing VoIP telephone
industry in which the products of the different vendors work together like
the products in the computer industry do today. We believe that having a
choice is good for you and therefore good for us.
This manual gives you a brief introduccion to the snom 4S SIP
Registrar/Proxy. For additional snom 4S information, please visit our Web
site at http://www.snom.com and if you have any comments and

suggestions about snom 4S, please contact us through snom technology
AG’s support link Web site. We would appreciate your feedback.
We hope that this SIP proxy helps you get VoIP up and running!
Thank you!

CEO & Founder

Logging in
The snom4S gives you access to “your” telephone system. You
can use a web browser to log on into your system, see who was calling
you, initiate conferences or change your preferences. You can do this from
anywhere in the Internet. If your telephone is turned on or off does not
matter.
The rst time when you access the telephone system, you need
to ll in your username and domain name just like the SIP telephone
number that you have received with your account. Please don’t use the
sip: in front of the URL. Most of the modern web browsers remember your
password when you type it in, so next time the browser will help you lling
in name and password.

After you are logged in, a session-key is assigned to you. This
session key will be valid for one hour (this is the default value if it is not
changed by your system administrator); each time you access another
page with this session key, the timer for the session will be reset. If you
want to explicitly delete your session, click on the logout button in the
navigation bar.
On the main screen of your log in you see the call list. This is the
list of the last hundred calls that affected your account. By clicking on the
number, you may connect to that number (this feature is not available on
all systems). You can also see the time and the duration of the call.
On the left side of the screen you see a navigation bar. On the top
of this navigation bar, you see the menu. Some menu items appear only
if the functionality is available for you.

Initial Setup
In the preferences screen you may change your personal
preferences. Please enter your display name here, this name will be
downloaded into your endpoints (if they support plug and play).
Also, you should enter your web password here. This password
protects the web access; the password for registering your phone is a
different one which can only be changed by the administrator. Please also
not that entering your password in an insecure http connection might be
captured by an eavesdropper. If you are using https, your data is safe.

The snom 4S offers you several ways to redirect your calls.
Often, you want to redirect your phone calls to another number (we call
this “home”, but it does not have to be necessarily your home number).
The mailbox is always used if reaching timed out. The timeout period is
up to you. If you don’t provide a timeout value, the proxy chooses 20
seconds.
When someone calls you on your account, the proxy inserts a
hint into the invitation message that indicates the phone how to ring. This
is helpful because you don’t have to look at the phone to nd out who is
being called. To check the ring tone, just click on the links shown in the
dialog. Your PC will give you an idea on how it sounds. If you want to leave
the ring tone to the phone, select “Use Phone Settings”.
The email address is important if you wish to receive email
notications when someone left a message on your mailbox. You can
select the mode in which the mail is set up.

Specifying where
you are
On the left side of the screen, you can click on where you are.
In the Ofce
Means that the proxy should search where you are registered. If
you are not registered anywhere the proxy will directly do to the mailbox,
if it has been set up.
At Home
Will try to get you in the address that you specied as “home”.
Also, if the proxy could not nd you there, it will go to the mailbox.
When you select On the Road, you need to specify where
the proxy should look for use. You may enter a SIP URL here, or just a
telephone number. The proxy will automatically translate the location into
a valid SIP URL.
If you select Ofine, the proxy will immediately go to the
mailbox.

Conferencing
The snom 4S offers you a simple way to initiate a conference. All
you need to do is ll in the numbers of the participants and press start.
Please make sure that you are really available on the location
that you specied in the navigation bar. The proxy will rst initiate a
call to you. If you pick up, the proxy will initiate the calls to the other
participants.
The conferencing feature needs to be enabled by your domain
administrator.

Messages
If you are not registered, the proxy stores messages for you and
delivers them when you register again. In this folder you can see the
messages which are stored for you.
Speed Dial Lists
If your administrator assigned you the responsibility of a speed
dial list, you will see additional links in your navigation bar. You see
a simple example below, where the number 911 is replaced with the
SIP URL “sip:[email protected]” and the number 912 with “sip:
[email protected]”.
If you have just a few speed dial entries, you might want to edit
them directly in the window in the web browser. The format is simple and
you will nd a little description already on the web page. To dene the
speed dial mapping, enter one line per mapping. The rst word indicates
the speed dial number and the second word (separated by space) indicates
the mapped number. You may enter as many mappings as you need.

If you maintain long lists of speed dial numbers, we recommend
using a text editor to edit the le in a separate space and copy & paste
this le into the web browser edit eld.

Setting Groups
Setting groups are similar to the speed dial list in a way that you
might have been assigned for administration of such a setting group.
Normally you need to change only a few settings. You may select
the language from a pull down menu. The tone scheme denes how the
ring back and busy tones will sound on your phones. The time zone is
important to make sure that the phones have the right time.

Programmable
Keys
If your phones have programmable keys, you may specify here
what their function is. This is a helpful function in groups that should see
the same park orbit or have the same intercom addresses.
The ve programmable keys on snom200, for example, have the following
options:
§ Line
§ Destination
§ Intercom
§ Park Orbit
§ Voice Recorder
Each of these buttons has an LED indicating the status of the
respective programmable key at any given time.
Some features are common to all these options:
a. Pressing a button when its LED is blinking and the phone is ringing
will receive the call.
b. Pressing the button when a call is in progress at that key, indicated
by the constantly on LED, will put the call on hold.
c. Pressing a button while editing a number for dialing at that key will
erase the number and the phone will go to idle state.
Each one of these different options will now be explained in
detail. 7

Line
“Line” can be used in one of these ways:
a. To map a local sip line:
A user can assign the local lines to programmable keys by
selecting this option and setting the url of the local line as argument to
that key setting e.g. if a phone has 2 registrations [e-mail] and
[e-mail]. The user has the option to map two programmable
keys to each one of these lines by selecting ‚Line‘ and setting the
respective sip url as argument. If so, all the calls to a particular line will
go to its matching programmable key e.g. if [e-mail] was
mapped at Key P2, the led on that key will start blinking if there is an
incoming call on that line. Similarly, if the user pressed P2 in the idle
state, [e-mail] will become the active line for that call. This
feature is to facilitate the customers to use their different sip accounts as
they would use different PSTN phone lines. It is also possible to assign
different ringtones for each sip line to make an acoustic differentiation.
This can either be done at the proxy or at Settings/Sip/Lines page on the
phone web interface.
b. To map a sip url for call pickup:
Selecting this option with a sip url as argument will subscribe
for dialog state changes of the phone with that registration. The led
on that key will show the status of the registration as idle, talking or
ringing by variable frequency of blinking. This allows the user to pickup
a ringing call remotely, just by the press of a button. An example of its
usage can be mapping the ofce reception phone line at the phone of
company secretary. If for some reason a ringing phone is not answered
at the reception, secretary can see its ringing status by the blinking led
and pickup the call by just pressing that programmable key. No calls go
unanswered this way.
c. Free Key:
“Line” is also the default setting for the programmable keys. If
no argument is set, the keys are treated as free. Outgoing and incoming
calls, not bound to any other key, go to the rst such free key.
