SNOM 820 MANUAL V.8 THE SNOM 820 - THE 8 EXPERIENCE

THE SNOM 820 - THE 8 EXPERIENCE

VOIP - MAKING CALLS VIA THE INTERNET

When using VoIP (Voice over Internet Protocol) you are not phoning via ded­icated phone lines as you do when you are using conventional phones;
instead the audio data is digitized and transmitted over the internet in the
form of data packets.

With snom VoIP phones you can cut down on phone costs and communi­cate with other participants over the internet without losing audio quality. Via
a gateway you can also communicate with parties on landlines and in cell
phone networks.

To be able to use VoIP you need to have:

1. A broadband internet connection.

2. 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.

3. Account information provided by your network administrator or a VoIP
account with a VoIP provider who supports the VoIP SIP standard. With
your snom 820 you can use up to 12 VoIP accounts with one or more
VoIP providers. You need to obtain your access number (“phone num­ber”) and the necessary access data to register your phone and make
phone calls; the requirements differ from provider to provider. They may
include:

• A user name, if required;

• Your login name;

• The address of the server (registrar);

• Provider-specific settings, if required.

snom phones are plug-and-play. Once you have connected the hardware
and entered the data required by your provider, you are good to go. In most
cases your phone will register and initialize automatically.

Enjoy your new phone!

3. Attach the footstand.

4. 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.

5. Insert the plug of the power supply into the connector labeled “DC 5V”
and hook up the plug to the mains.

6. If you want to use a headset, connect it to the RJ audio jack labeled
“EHS”.

7. Place the phone on an even, horizontal surface.

INITIALIZATION

snom phones are plug-and-play. In most cases your phone will register and
initialize automatically.

1. Connect the phone to your network or your router.

2. Do not touch any keys while registration and initialization are taking
place. The process usually takes a couple of minutes.

3. You will be prompted in English to select a language.

VoIPon www.voipon.co.uk [e-mail] Tel: [phone] Fax: [phone]

SNOM 820 MANUAL V.8 SETTING UP THE PHONE

4. Next, you will be prompted in the language of your choice to select a
timezone. Timezones shown depend on the language you have chosen;
you can collapse and expand the list for quicker access - see page 24.

5. Next, you will be prompted to enter an account, normally the login name
you received from your provider, and the registrar - see page 5. To enter
the period (.), change the input mode (see “Entering Letters, Numerals,
and Special Characters” on page 15) to small or capital letters and
press the “1” key once. To enter the @ sign, change to letter mode and
press the “1” key three times.

6. Your phone was successfully registered if the display shows a green
phone with the account (phone number) you entered.

7. Don’t worry if time and date are wrong or in a format you don’t want.
See page 9 on how to change them.

8. If you see the phone symbol and the account on the display but they are
not highlighted 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 time.

WHAT TO DO WHEN REGISTRATION AND INITIALIZATION WERE

UNSUCCESSFUL

• Contact your network system administrator if the phone is operating or
supposed to be operating within a network.

• If you are using a VoIP provider you may need to enter further data, as
specified by your provider.

a. Open the phone’s web interface - see page 19.
b. Open Configuration Identity 1 and enter any additional login informa-

tion you have received from your provider - see page 45.

c. 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 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.

• If your IP telephone system does not support automatic initialization,
contact your administrator or see our web page www.snom.com/Wiki for
manual phone initialization.

SETTING/CORRECTING THE TIMEZONE

page does not open, you are in user mode. Change to administrator
mode or contact your administrator to change the timezone
