Attaching and detaching the footstand
The footstand can be attached at two dierent angles: 28° and 46°.
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 (Fig. 1) below the slideguides on the back of the
phone (Fig. 2). For the upright position, the short "legs" of the footstand must be attached to the
phone; for the more horizontal position, use the long ones.
2. Push the footstand upwards onto the slideguides until they lock in place (Fig. 3).

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.
Fig./Abb. 1 Fig./Abb. 2 Fig./Abb. 3
1. Slide the plastic tab from the cradle (Fig. 1).
2. Rotate the tab 180°.
3. Slide the tab back into the cradle (Fig. 2). The top of the tab now protrudes slightly above the
inner edge of the cradle (Fig. 3), so that it will hold the handset more securely.
The wall mounting instructions are attached at "Appendix 3 - Wall mounting" on page 91.

D712/710 User Manual Setting up the Phone
Connecting the phone
The phone can be operated with Power over Ethernet (PoE) provided via the network cable or, if PoE is

• 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, you can use the A6 power supply which is available separately. Insert
the plug of the power supply into the connector labeled "DC 5V" and hook up the plug to the wall
outlet.
Warning: Other power supplies may damage or destroy the phone, aect its behavior,
or induce noise.

13
D712/710 User Manual Setting up the Phone
Connecting a headset
• If you want to use a wired headset, connect it to the RJ audio jack labeled .
• If you want to use a wireless headset, you need the Snom EHS Advanced wireless-headset
adapter to connect to the base station of the wireless headset. Insert the plug of the 7xx adapter
cable into the connector on the phone, as shown in Fig. 1, 2, and 3, below.
Note: You need to remove the footstand to gain access to the connector (see "Attaching
and detaching the footstand" on page 10). 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.
Do not insert the plug upside down (Fig. 4)!
Please refer to the Quick Installation 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.

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 dierent 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 four 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 dier from provider to provider. They normally
include:

14
D712/710 User Manual Setting up the Phone
• 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 68.
Initialization and registration
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.
You will then be asked on the display to make some basic settings.
1. You will be prompted in English to select a language. Use on the navigation key 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. The time zone
determines the time shown on your display.
◦Press the function key underneath Jump to move to the beginning of the next time zone.
◦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 move up or down the list one item at a time.
◦Press to save the time zone preceded by .
3. Next, you will be prompted to select the tone scheme of a country. This aects the dial tone you
hear when you pick up the receiver. Dierent countries use dierent 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 start registering the first account.
5. Enter the account number. Save with .
Note: See "Entering numerals, letters, special characters, and symbols" on page 21
on how to enter numbers and letters.
6. Enter the registrar. Press .

15
D712/710 User Manual Setting up the Phone
7. If prompted, enter the password received from your administrator or VoIP provider and 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 (see ""Opening the
web interface" on page 29.
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 dierent from snom’s standard factory settings. snom’s web page
lists numerous providers and PBXs that have been tested for interoperability with
our phones and specific settings that may be required. Do not change the standard
configuration unless you know what you are doing. Expert help may be required.
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 and date formats" on page 71.
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 "Time" on page 72.
• 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" on page 72.
