Attaching and detaching the footstand
The footstand can be attached at two different angles: 55° and 33°.
Note: Before attaching the footstand to the phone, plug the long end of the handset
cord into the connector labelled " " on the back of the phone and place the cord in the
cable guide.
1. Place the top of the grooves on the footstand below the slideguides on the back of the phone.
2. Push the footstand upwards onto the slideguides until they lock in place.

3. Plug the short end of the handset cord into the connector on the handset.
4. Place the phone on an even, horizontal surface.
Rotating the tab of the cradle
The phone is delivered with the tab level with the inner edge of the cradle. If you are going to mount
the phone on a wall, we recommend that you rotate the tab 180°. After rotation, the tip of the tab will
protrude slightly above the edge of the "cradle". The small rectangular hole in the receiver casing fits
perfectly over the now protruding tip, holding the receiver safely in place in the upright position on the
wall.

• Plug the Ethernet (network) cable into the RJ45 connector labeled “NET”, and plug the other end
into the network side to establish a data link. The second RJ45 connector, labeled “PC”, is for
daisy-chaining further Ethernet devices without the need for a second Ethernet connection line.
• If PoE is not available, use a 5V DC power supply (not included in delivery).
Note: Use only a power supply expressly recommended by snom; other power supplies
may damage or destroy the phone, affect its behavior, or induce noise. Insert the plug of
the power supply into the connector labeled “DC 5V”, and hook up the plug to the wall
outlet.

snom 720 User Manual Setting up the Phone
Connecting a headset
You can use wired as well as wireless headsets with the phone.
• Wired headsets
If you want to use a wired headset, connect it to the RJ audio jack labeled " ".
Note: If both a wired and a wireless headset are connected to the phone, incoming calls
will go to the wireless headset.
• Wireless headsets
You need a Bluetooth-compatible adapter to use a Bluetooth-compatible headset with your phone.
◦Connecting the base station of your headset via the snom EHS Adapter
Connect the snom connector of the 7xx adapter cable to the port on the back of the phone, as
shown in Fig. 1 and 2, below.
Note: You need to remove the footstand to gain access to the connector (see
"Attaching and detaching the footstand" on page 12). After you have inserted
the plug, make sure that the cable is lying flat against the bottomshell of the phone
while you are attaching the footstand to the phone. Twisting or curling up the
cable may result in damaging the cable and the wires inside it.
Please refer to the Quick Start Guide of the snom EHS Advanced and the manual of your
wireless headset for further information on how to connect the snom EHS Advanced and the
headset.
Fig. 1 Fig. 2
◦Connecting the headset to the phone via a Bluetooth-compatible adapter
Insert the adapter into the USB port on the back of the phone. See also the Quick Start
Guides of the snom USB BT and the snom HS BT or the manual of the third-party headset.
Attention: Starting with firmware version 8.7.2.11, the snom HS BT's parameter
will be the default setting for USB headsets.
If your phone is running an earlier firmware version, enter the parameters of the
snom HS BT manually on the phone's web interface at > Advanced > Audio >

Initializing and registering the phone
Prerequisites
To be able to use VoIP, you or your company must have:
• A broadband internet connection.
• Access to the internet via a router. This could be a separate device available in various versions
from many different manufacturers or in the form of a router on a server or a PC.
• Account information provided by your network administrator or a VoiP account with a VoIP service
provider who supports the VoIP SIP standard. The phone supports up to 12 VoIP accounts with
one or more VoIP providers.
You will need the registration information received from your Internet service provider or your network
administrator. Required and optional data differ from provider to provider. They normally include:
• Account (usually the phone number). On snom phones, an account is called an "identity".
• Registrar
• Password
User name, authentication name, outbound proxy may also be required. These are settings that can
only be configured on the web interface of the phone after it has been successfully registered. If
your provider or your network provides a mailbox account, that setting is also configured on the web
interface. For more information, see "Identities/accounts" on page 64.
Initialization
snom phones are plug-and-play. Once the phone is connected to your network, it will begin to initialize.
Note: Normally the initialization is completely automatic, using DHCP. If the phone
cannot discover a DHCP server in the subnet, you will be asked: Are you using DHCP?
If your network does not support DHCP, press and enter the IP address, netmask, IP
gateway, and DNS server manually. Ask your Internet service provider or your network
administrator for them.
Watch the display and, when asked to, make selections with and save with .
1. You will be prompted in English to select a language. Use to select another language, if
applicable, and press to save the language preceded by .
2. Next, you will be prompted in the language of your choice to select a time zone. This affects the

17
snom 720 User Manual Setting up the Phone
time shown on your display.
◦Press the function key underneath Jump to move to the beginning of the next time zone.
◦Press to move up or down the list one item at a time.
◦Press the function key underneath Reduc to show only those time zones where the selected
phone language is spoken.
◦Press the function key underneath More to show all time zones.
◦Press to save the time zone preceded by .
3. Next, you will be prompted to select the tone scheme of a country. This affects the dial tone you
hear when you pick up the receiver. Different countries use different dial tones.
◦Press to move up or down the list one item at a time.
◦Press to save the tone scheme of the country preceded by .
4. The display shows the "Welcome" screen. Press any key to log on.
5. Enter the account number. Save with .
Note: See "Entering numerals, letters, special characters, and symbols" on page 24 on
how to enter numbers and letters.
6. Enter the registrar. Press .
After successful registration you will see the phone symbol and the registered account (identity) in
the identity line underneath the date/time bar:
Infobar with date & time
Identity line
Note: If you see the account on the display preceded by an empty square and the
phone does not work, the server may be down, either for servicing or due to a malfunction.
The registration and initialization should be completed as soon as the server is up and
running again. You may want to check with your administrator or your provider if nothing
happens within a reasonable amount of time.
What to do if initialization and registration are unsuccessful
Your network or your VoIP provider may require more login data than requested by the snom phone
during the initialization and registration process. This data is entered on the web interface of the
phone. Contact your network system administrator or your VoIP provider for more information.
1. When you have received all necessary data, open the phone’s web interface.
2. Open Configuration Identity 1 and enter any additional login information you have received from
your provider.
Note: A number of IP telephony service providers and a number of SIP PBXs require
settings that are different from snom’s standard factory settings. snom’s web page lists
numerous providers and PBXs that have been tested for interoperability with our phones

snom 720 User Manual Setting up the Phone
Correcting the clock
The phone receives the time and date from your NTP time server. If the time and/or date on the display
are incorrect, you may need to set the correct time zone.
Changing the settings: See "Time zone" on page 67.
If the time is still incorrect, there may be a problem with the time server. Contact your network
administrator or your IP provider.
Default formats:
• Time. 24-hour clock, e.g. 17:35. Changing to AM and PM formats: See "Date and time formats"
on page 67.
• Date. US date format MM/DD/YEAR, eg. 11/23/2010. Changing to European format
DD.MM.YEAR, e.g. 23.11.2010: See "Date and time formats" on page 67.
