Audience
This guide is written for installers and system administrators. It assumes that you are
familiar with networks and VoIP, both in theory and in practice. This guide also assumes
that you have ordered your IP PBX equipment or service and selected which PBX features
you want to implement. This guide references specific IP PBX equipment or services only
for features or settings that have been designed for a specific service. Please consult your
equipment supplier or service provider for recommended switches, routers, and firewall
and NAT traversal settings, and so on.
As the C520 Conference becomes certified for IP PBX equipment or services, Snom may
publish interop guides for those specific services. The interop guides will recommend
second-party devices and settings, along with C520-specific configurations for optimal
performance with those services. For the latest updates, visit our Wiki at
http://wiki.snom.com/Category:C520.
The download links for the Quick Installation Guides and the User Manual for the C520

About the C520 conference phone
The C520 WiMi Conference Phone is a conference phone designed to work with popular
SIP telephone (IP PBX) equipment and services. Once you have ordered and configured
your SIP equipment or service, the C520 enables you to make and receive calls as you
would with any other business phone. In addition to its speakerphone and conferencing
features, the C520 provides calling features like hold, transfer and speed-dial numbers.
The C520 conference phone features include:

2.5-inch backlit Liquid Crystal Display

Bluetooth and DECT connectivity for cell phones and headsets

Up to 3 SIP account registrations

Up to 6 active SIP sessions

3-way conferencing

200-entry Call Log
You can configure the C520 using the menus on the phone, a browser-based interface
called the WebUI, or an automatic provisioning process (see “Provisioning Using
Configuration Files” on page 85). The WebUI enables you to configure the C520 using a
computer that is connected to the same Local Area Network. The WebUI resides on the
device and may get updated with firmware updates.

Network Requirements
A simple C520 WiMi Conference Phone installation example is shown in Figure 1. A
switched network topology is recommended for your LAN (using standard 10/100 Ethernet
switches that carry traffic at a nominal rate of 100 Mbit/s).
The office LAN infrastructure should use Cat.-5/Cat.-5e cable.
The C520 requires a wired connection to the LAN. However, wireless connections from
your LAN to other devices (such as laptops) in your office will not impede performance.
A Dynamic Host Configuration Protocol (DHCP) server is recommended and must be on
the same subnet as the C520 conference phones so that IP addresses can be
auto-assigned. In most cases, your network router will have a DHCP server. By default, the
C520 has DHCP enabled for automatic IP address assignment.
Some DHCP servers have default settings that limit the number of network IP
addresses assigned to devices on the network. You should log in to your server
to confirm that the IP range is sufficient.
If no DHCP server is present, you can assign a static IP to the C520. You can assign a
static IP address using the C520 menu. To assign a static IP, go to Admin settings >
Network setting > Set static IP. If you do not have a DHCP server or do not manually
assign static IPs, you will not be able to access the WebUI and/or enable automatic time
updates from an NTP server.
A DNS server is recommended to resolve the path to the Internet and to a server for
firmware and configuration updates. If necessary, the system administrator can also
download upgrade files and use the WebUI to update the C520 firmware and/or
configuration settings manually.

C520 Configuration Methods
You can configure the C520 using one of the following methods:

From the C520 itself, using the menus. The C520 menus are best suited to
configuring a few settings, perhaps after the initial setup has been done. For
administrators, the settings available on the C520 menus include network
settings, account settings, and provisioning settings. See “Using the Admin
Settings Menu” on page 24. Many of the settings accessible on the C520 are
most useful for end users. Through the menu, they can customize the screen
appearance, sounds, and manage calls. For more information, see the C520
User Guide.

The Web User Interface, or WebUI, which you access using your Internet browser.
See “Using the WebUI” on page 30. The browser-based interface is easy to
navigate and best suited to configuring a large number of C520 settings at once.
The WebUI gives you access to every setting required for configuring a single
device. You can enter service provider account settings on the WebUI, and set up
provisioning, which will allow you to automatically and remotely update the C520
after initial configuration.

Provisioning using configuration files. Working with configuration files allows you to
configure the device at regular intervals. There are several methods available to
enable the C520 to locate and upload the configuration file. For example, you
can enable the C520 to check for the presence of a configuration file on a
provisioning server when it starts up or reboots. If the configuration file is new or
has been modified in any way, the C520 automatically downloads the file and
applies the new settings. For more information, see “Provisioning Using
Configuration Files” on page 85.

C520 WiMi Administrator and Provisioning Manual
Adding a Custom Logo
You can upload a custom logo to be displayed on the phone idle screen and during bootup.
Uploading a logo is done using the configuration file. The parameters for uploading a
custom logo are described in “Uploading a custom logo” on page 16. The default logo for
bootup and idle mode is the Snom logo.
The behavior described below is disabled by default.
You can enable the logo to appear instead of the idle screen after a specified period of
inactivity. The parameter for setting the delay before the logo appears is in the General
configuration file. See “user_pref.idle_to_logo_timeout” on page 127.
You can enable the phone screen to cycle between the logo and the idle screen when the
phone is in idle mode by setting both the user_pref.idle_to_logo_timeout and the
user_pref.logo_to_idle_timeout parameters. See
“user_pref.logo_to_idle_timeout” on page 127.
Logo specifications
The file type and dimensions for the logo are listed below.
File type:
Monochrome bitmap (.bmp)
Dimensions (w × h): Idle screen and bootup logo: 158 × 57 pixels
Positioning a custom logo on the screen is a matter of creating a logo with the maximum
dimensions listed above, including any surrounding white space. Note that the width of the
logo specified in the table above is the same as the width of the C520 screen (158 pixels).
There are no configuration file settings to specify the x-axis or y-axis position of the logo on
the screen.
Introducing the C520

C520 WiMi Administrator and Provisioning Manual
Uploading a custom logo
The file.bootup_logo and file.idle_logo parameters in the configuration file allow you to
upload a custom bootup logo and custom idle logo. Place the logos on your server and
enter the URL for each logo for the file.idle_logo and file.bootup_logo parameters.
If the downloaded logo is found to be invalid, the syslog will record one of the following
errors:

file not found

invalid file format

incorrect image size

image is not in black and white
Custom logo user interactions
For C520 users, pressing any hard key will exit the idle logo and perform the key's
function. For example, pressing MENU will show the Main Menu.
Pressing a soft key when the idle logo is showing will switch to the idle screen.

Customizing Soft Keys
The configuration file allows you to select which soft keys can appear on the Idle screen,
the Active Call screen, the Held Call screen and the Live Dial screen. You can also specify
the position of each soft key.
Some soft keys appear only under certain conditions. For example, the Line soft key on the
Idle screen appears only if there is more than one registered SIP account. When a
"conditional" soft key is not visible, the soft key's position is left empty.
Soft key levels with no soft keys will not be shown if there are multiple soft key levels (as
indicated by the  and  icons). Any soft key level where all soft keys are invisible will be
dynamically skipped when the user navigates through the available levels. On the C520, a
soft key level consists of three soft keys (populated or blank) in a row.
Table 2 shows the soft key options available for each screen. Each screen can have a
maximum of nine soft keys.
For the custom soft key configuration file parameters, see “"softkey" Module: Custom Soft
Key Settings” on page 144.
Custom soft key configuration file settings
You cannot edit soft key text. The configuration file parameters allow you to only
select and position the soft keys for each screen.

C520 WiMi Administrator and Provisioning Manual
Dial Plan
The dial plan consists of a series of dialing rules, or strings, that determine whether what
the user has dialed is valid and when the C520 should dial the number.
Numbers that are dialed when forwarding a call—when the user manually
forwards a call, or a pre-configured number is dialed for Call Forward All, Call
Forward–No Answer, or Call Forward Busy—always bypass the dial plan.
Dialing rules must consist of the elements defined in the table below.
Element
Description
x
Any dial pad key from 0 to 9, including # and *.
[0-9]
Any two numbers separated by a hyphen, where the second number is
greater than the first. All numbers within the range or valid, excluding # and *.
x+
An unlimited series of digits.
,
This represents the playing of a secondary dial tone after the user enters the
digit(s) specified or dials an external call prefix before the comma. For
instance, "9,xxxxxxx" means the secondary dial tone is played after the user
dials 9 until any new digit is entered. "9,3xxxxxx" means only when the digit
3 is hit would the secondary dial tone stop playing.
PX
This represents a pause of a defined time; X is the pause duration in
seconds. For instance, "P3" would represent pause duration of 3 seconds.
When "P" only is used, the pause time is the same as the Inter Digit Timeout
(see “SIP Account Management” on page 34).
(0:9)
This is a substitution rule where the first number is replaced by the second.
For example, "(4:723)xxxx" would replace "46789" with "723-6789". If the
substituted number (the first number) is empty, the second number is added
to the number dialed. For example, in "(:1)xxxxxxxxxx", the digit 1 is
appended to any 10-digit number dialed.
|
This separator is used to indicate the start of a new pattern. Can be used to
add multiple dialing rules to one pattern edit box.
A sample dial plan appears below.

Ringer Settings
The Ringer Settings enable you to provide a distinctive ringing feature via the custom
Alert-Info header associated with an incoming call. This setting overrides the ringer tone you
have set for the account. For example, you can set a unique ringer tone to alert the C520
user upon receiving any incoming calls tagged as "important" in the Alert-Info header.
The SIP Invite message contains an Alert-Info header that the phone checks in order to
determine which ringer tone to play. The Alert-Info header format is as follows:
Alert-Info: info=info_text
If the header contains the "info" parameter, the phone attempts to match it to the Distinctive
Ringing Text. If there is a match, the associated tone will play. If there is no match, the
default tone for the account will play.
The matching is done on a "first match" basis. In the case of duplicate text strings, the ringer
tone associated with the first matched entry in the Distinctive Ringing Text list will play.
The server-side configuration must be done with your service provider. The SIP Invite text
("Distinctive Ringing Text" on the Ringer WebUI page) must be entered in the format ringerx,
where x is the ringer number from 1 to 10. For example, to match Ringer 1 enter ringer1.
The ringer settings are also available as parameters in the configuration file. See
“"ringersetting" Module: Distinctive Ringer Settings” on page 134.

Paging Zones
On the Paging Zones page, you can enter the multicast IP addresses that the phone will
monitor. When a page is sent out using this multicast IP address, all phones that are
programmed to monitor that IP address will receive the paging RTP stream and play the
page on their speakerphone. You can also enable the phone to send out multicast pages
using a particular multicast IP address.
You must first set up paging groups (each group consisting of a multicast paging IP address
and assigned User IDs) on your SIP PBX. The C520 can monitor a maximum of 10
multicast IP addresses.

lower-priority zone's active page.
In addition, a call priority setting is available in the
configuration file (page_zone.call_priority_threshold). This
priority setting also ranges from 1 to 10 (2 is the default). If
the paging zone priority is higher or equal to the call
priority, then a multicast page can interrupt an active,
dialing, or incoming call.
Enable Incoming Page
Select to enable the C520 to receive incoming pages for that
paging zone. If the "Enable Incoming Page" checkbox is not
selected, the phone will not listen for the multicast, but will

Provisioning
Provisioning refers to the process of acquiring and applying new settings for the C520
using configuration files retrieved from a remote computer. After a C520 is deployed,
subsequent provisioning can update the C520 with new settings; for example, if your
service provider releases new features. See also “Provisioning Using Configuration Files”
on page 85.
With automatic provisioning, you enable the C520 to get its settings automatically—the
process occurs in the background as part of routine system operation. Automatic
provisioning can apply to multiple devices simultaneously.
With manual provisioning on the WebUI, you update the C520 settings (configuration
and/or firmware) yourself via Provisioning > Import Configuration and/or Firmware
Upgrade > Manual Upgrade. Manual provisioning can only be performed on one C520
at a time.
On the Provisioning page, you can enter settings that will enable the C520 to receive
automatic configuration and firmware updates. The Provisioning page also allows you to
manually update C520 configuration from a locally stored configuration file using an
Import function. You can also export the C520 configuration—either to back it up or apply
the configuration to another C520 in the future—to a file on your computer.
The provisioning process functions according to the Resynchronization settings and
Provisioning Server Settings. The C520 checks for the provisioning URL from the
following sources in the order listed below:
1. PnP—Plug and Play Subscribe and Notify protocol
2. DHCP Options
3. Preconfigured URL—Any C520 updated to the latest firmware release will have the
Redirection Server URL available as the default Provisioning Server URL (see
“provisioning.server_address” on page 111).
Using the Redirection Service requires contacting the VTech support team for an
account.
If one of these sources is disabled, not available, or has not been configured, the C520
proceeds to the next source until reaching the end of the list.
The provisioning settings are also available as parameters in the configuration file. See

Import Configuration
You can configure the C520 by importing a configuration file from your computer or your
local network. For more information about configuration file types and configuration file
formatting, see “Provisioning Using Configuration Files” on page 85.
To import a configuration file:
1. Click
to locate and open the configuration file.
2. Click
.
The C520 will update its configuration.
Manually importing a configuration file differs from the auto-provisioning process in that:

The C520 does not check whether the file has been loaded before. The
configuration file is processed whether or not it is different from the current version.

The C520 will restart immediately after importing the configuration file, without
waiting for one minute of inactivity.
Export Configuration
You can export all the settings you have configured on the WebUI and save them as a
configuration file on your computer. You can then use this configuration file as a backup, or
use it to update other phones.
Under Export Configuration, you can also reset the phone to its default configuration.
The exported configuration file will contain the following passwords in plain text:
 SIP
account authentication password

EAPOL password

Firmware server password

Provisioning server password

Encryption passphrase

LDAP server password

Broadsoft directory server password.
Please ensure that you save the exported configuration file in a secure location.
You can also disable passwords from being exported as plain text. See
“provisioning.pwd_export_enable” on page 115.

Exporting a configuration file generates two header lines in the configuration file. These
header lines provide the model number and software version in the following format:
#Model Number = xxxxxxx
#SW Version = xxxxxxx
You can use the exported file as a general configuration file, and duplicate the settings
across multiple units. However, ensure that you edit the file to remove any MAC-specific
SIP account settings before applying the general configuration file to other units.

PROVISIONING USING CONFIGURATION
FILES
Provisioning using configuration files is the quickest way to configure multiple C520 conference
phones. You can place configuration files on a provisioning server, where the C520 conference
phones retrieve the files and update their configuration automatically.
Configuration files have the extension .cfg and contain settings that will apply to C520
conference phones. To edit a configuration file, open it with a text editor such as Notepad.
The settings within a configuration file are grouped into modules. Most of the modules
group their settings in the same way that settings are grouped on the C520 WebUI. For
example, the "time_date" module in the configuration file contains the same settings that
are on the Time and Date WebUI page. For a complete list of C520 configuration file
modules and their associated parameters, see “Configuration File Parameter Guide” on
page 93.
Using the WebUI, you can also import a configuration file and apply the configuration file
settings to the C520. For more information, see “Import Configuration” on page 78.

C520 WiMi Administrator and Provisioning Manual
The Provisioning Process
The automatic provisioning process is as follows:
1. Check for new or updated configuration files. For file-checking options, see
“Provisioning” on page 74 and “Resynchronization: configuration file checking” on
page 87. The C520 maintains a list of the last loaded provisioning files. The C520
compares its current configuration against the files it finds on the provisioning server.
Checking for update… appears on the C520 screen.
If provisioning has been triggered by the resync timer expiring or by remote
check-sync, the C520 checks for updated files after one minute of inactivity.
2. Download the configuration files.
If any file on the provisioning server has changed, the C520 treats it as a new file and
downloads it.
If the provisioning URL specifies a path only with no filename, then by default the
C520 looks for and retrieves the following two files:

General file: <model>.cfg.

MAC-specific file: <model>_<MAC Address>.cfg.
The <model> variable is the VTech product model: C520-WiMi, for example.
If the provisioning URL specifies both a path and filename, then the C520 retrieves
only the configuration file specified.
3. The C520 restarts after one minute of inactivity.
During provisioning, the C520 reads the configuration file and validates each module and
setting. The C520 considers a setting valid if it is:

a valid data type

formatted as a valid setting

within a valid data range

part of a module that passes an integrity check. That is, the module's settings are
consistent and logical. For example, in the "network" module, if DHCP is disabled,
but no static IP address is specified, the module will fail the integrity check and
none of the settings will apply.
Invalid modules or invalid settings are skipped and logged as ERROR messages in the
system log, but will not interrupt the provisioning process. The system log will include the
module parameters that have not been applied. A recognized module with unrecognized
settings will cause all other settings in that module to be skipped.
A successful configuration or firmware update is reported as an INFO message in the
system log.
See “Configuration File Parameter Guide” on page 93 for the options and value ranges
available for each configuration file setting.

C520 WiMi Administrator and Provisioning Manual
Resynchronization: configuration file checking
You can select a number of options that determine when the C520 checks for new
configuration files. This process of checking for configuration files is called
Resynchronization. Resynchronization options are available on the WebUI Provisioning
page, but you can also include them in a configuration file.
The resynchronization options are:

Mode—sets the C520 to check for a configuration file only, a firmware update
file only, or both types of file.

Never—configuration file checking is disabled

Bootup—the C520 checks for new configuration files when it boots up. Any
updates are applied during the boot-up process.

Remote check-sync—enables you to start a resynchronization remotely using your
hosted server's web portal. The Remote check-sync settings are available only in
the configuration file, not the WebUI.

Repeatedly, at a defined interval from 60 to 65535 minutes (45 days).
C520 restart
If the C520 needs to restart after an auto-update, the restart happens only after the device
has been idle for one minute.
To prevent users from delaying the update process (auto-updates cannot begin until the
C520 has been idle for one minute), or to avoid device restarts that might interfere with
incoming calls:

set the resynchronization interval to a suitable period

upload any new configuration file(s) to your provisioning server after work hours so
that the C520 will download the file(s) when there is no call activity.
When you update the C520 by importing a configuration file using the WebUI, the device
restarts immediately after applying the new settings, regardless of whether the C520 is
idle.

C520 WiMi Administrator and Provisioning Manual
Configuration File Types
The C520 is able to retrieve and download two types of configuration file. Depending on
your requirements, you may want to make both types of configuration file available on your
provisioning server.
The two configuration file types are a general configuration file and a MAC-specific
configuration file. The types differ in name only. The formatting of the files' content is the
same.
The general configuration file contains settings that are required by every C520 in the
system.
The MAC-specific configuration file is a file that only a single C520 can retrieve. The
MAC-specific configuration file name contains a C520 MAC address and can only be
retrieved by the device with a matching MAC address.
The filename formats for both files are:

General file: <model>.cfg

MAC-specific file: <model>_<MAC Address>.cfg
The <model> variable is the Snom product model; for example, C520-WiMi. For more
information about the MAC-specific configuration file, see “Guidelines for the MAC-Specific
configuration file” on page 90.
If the provisioning URL specifies a path only with no filename, then by default the C520
will fetch both files.
However, if the provisioning URL specifies both a path and filename, then the C520 will
only fetch the single configuration file specified.
Both the general and MAC-specific files can contain any of the available configuration
settings. A setting can appear in the general configuration file or the MAC-specific
configuration file, or both files, or neither file. If a setting appears in both files, the setting
that is read last is the one that applies.
When the C520 fetches both a general and a MAC-specific configuration file, the general file
is processed first. You can configure a setting for most of your C520 conference phones in
the general file, and then overwrite that setting for just a few C520 conference phones using
the MAC-specific file.

C520 WiMi Administrator and Provisioning Manual
Data Files
The configuration file can also include links to data files for product customization. Allowed
data types include the following:

Directory (contacts, blacklist) in .xml format

Certificates (server, provisioning, LDAP, Broadsoft) in pem format

Logos (a bootup logo and an idle screen logo) in .bmp format
Links to data files are in the configuration file's "file" module. This is where you enter any
URLs to the data files that the C520 conference phone may require.
None of the data files are exported when you export a configuration file from the C520.
However, you can export a Directory or Blacklist .xml file using the WebUI. After modifying
the .xml file, you can use the configuration file "file" module to have the C520 import the
new file. For a complete list of data file parameters, see “"file" Module: Imported File
Settings” on page 135.
Provisioning Using Configuration Files

C520 WiMi Administrator and Provisioning Manual
Configuration File Tips and Security
All configuration settings are initially stored in a configuration template file. Copy, rename,
and edit the template file to create a general configuration file and the MAC-specific
configuration files you will need. You can store the general configuration file and the
MAC-specific files on your provisioning server.
Do not modify the configuration file header line that includes the model and firmware
version.
To save yourself time and effort, consider which settings will be common to all (or the
majority of) C520 conference phones. Such settings might include call settings, language,
and NAT settings. You can then edit those settings in the configuration template and save
it as the general configuration file. The remaining settings will make up the MAC-specific
configuration file, which you will have to copy and edit for each C520.
Clearing parameters with %NULL in configuration file
For configuration file parameters that can have a text string value, you can clear the value
of the parameter by applying the value %NULL in the configuration file.
For example: sip_account.1.display_name = %NULL
However, the following parameters are exceptions. Applying the value %NULL to these
parameters will reset them to their default value.

file.bootup_logo - applying %NULL restores the default value (VTech logo)

file.idle_logo - applying %NULL restores the default value (VTech logo)
Guidelines for the MAC-Specific configuration file
The C520 downloads the MAC-specific configuration file after the general configuration
file. You must create a MAC-specific configuration file for each C520 in your system. The
file name must contain the C520 MAC address, which is printed on a label on the of the
device, or available on the MENU > Status > Product Info screen. For example, a Snom
C520 conference phone with the MAC address of 00:11:A0:10:6F:2D would download
the C520-WiMi_0011A0106F2D.cfg file.
When renaming a MAC-specific configuration file, ensure the filename is all upper
case.
The MAC-specific configuration file contains settings intended exclusively for that C520
conference phone. Such settings will include SIP account settings such as display name,
user ID, and authentication ID.

C520 WiMi Administrator and Provisioning Manual
Securing configuration files with AES encryption
You can encrypt your configuration files to prevent unauthorized users modifying the
configuration files. The C520 firmware decrypts files using the AES 256 algorithm. After
encrypting a file and placing it on your provisioning server, you can enable the C520 to
decrypt the file after fetching it from the server.
The procedures in this section use OpenSSL for Windows for file encryption, as shown in
Figure 2.
To decrypt a configuration file, you will need a 16-character AES key that you specified
when you encrypted the file. The key (or passphrase) is limited to 16 characters in length
and supports special characters ~ ^ ` % ! & - _ + = | . @ * : ; , ? ( ) [ ] { } < > / \ # as well as
spaces.
The encryption of configuration files is supported only for the auto provisioning
process. Encrypt files only if you intend to store them on a provisioning server. Do
not encrypt files that you intend to manually import to the C520. You cannot
enable decryption for manually imported configuration files.
To encrypt a configuration file:
1. (Optional) Place your configuration file in the same folder as the openssl executable
file. If the configuration file is not in the same folder as the openssl executable file, you
can enter a relative pathname for the [infile] in the next step.
2. Double-click the openssl.exe file.
3. On the openssl command line, type:
enc -aes-256-cbc -pass pass:[passphrase123456] -in [infile] -out [outfile]
-nosalt -p
Elements in brackets are examples—do not enter the brackets. Enter a 16-character
passphrase and the unencrypted configuration file filename (the "infile") and a name for the
encrypted file ("outfile") that will result.

CONFIGURATION FILE PARAMETER GUIDE
This chapter lists the available options for all the settings within the C520 configuration
file. Most settings in the configuration file have an equivalent in the WebUI (see the settings
tables in “Using the WebUI” on page 30). However, the options you must enter when editing
the configuration file have a different syntax and format.
The settings are divided into modules. Most modules correspond to a page on the C520
WebUI. You may wish to reorganize the modules within the configuration file itself. The
configuration file settings can be listed in any order, and the configuration file will still be
valid.
The device supports the XML representation of settings and modules via an XML
structure. The settings XML representation is structured into sub tags. Settings are either
valid globally for all sip accounts or account-specific, grouped into modules.
One module example is sip_account, which holds the supported per account/identity
settings and its values.
Short form for sip account 1:
sip_account.1.sip_account_enable = 1
sip_account.1.display_name = 1001
sip_account.1.user_id = 030398331001

"sip_account" Module: SIP Account Settings
The SIP Account settings enable you to set up individual accounts for each user. Each
account requires you to configure the same group of SIP account settings. The SIP account
settings for each account are identified by the account number, from 1 to 3 for the C520.
For example, for account 1 you would set:
sip_account.1.sip_account_enable = 1
sip_account.1.label = Line 1
sip_account.1.display_name = 1001
sip_account.1.user_id = 2325551001
and so on. For account 2, you would set:
sip_account.2.sip_account_enable = 1
sip_account.2.label = Line 2
sip_account.2.display_name = 1002
sip_account.2.user_id = 2325551002
and so on, if you have additional accounts to configure.
The SIP account settings follow the format: sip_account.x.[element], where x is an account
number ranging from 1 to 3 for the C520.
All these settings are exported when you manually export the configuration from the
C520.

Appendix A: Maintenance
Taking care of your telephone

Your C520 conference phone contains sophisticated electronic parts, so you
must treat it with care.

Avoid rough treatment.

Save the original packing materials to protect your C520 conference phone if
you ever need to ship it.
Avoid water

You can damage your C520 conference phone if it gets wet. Do not install the
C520 conference phone near a sink, bathtub or shower.
Electrical storms

Electrical storms can sometimes cause power surges harmful to electronic equipment.
For your own safety, take caution when using electric appliances during storms.
Cleaning your telephone

Your C520 conference phone has a durable plastic casing that should retain its
luster for many years. Clean it only with a soft cloth slightly dampened with water
or a mild soap.

Do not use excess water or cleaning solvents of any kind.
Remember that electrical appliances can cause serious injury if used when you are wet or
standing in water. If the C520 conference phone should fall into water, DO NOT
RETRIEVE IT UNTIL YOU UNPLUG THE POWER CORD AND NETWORK CABLE FROM
THE WALL, then pull the unit out by the unplugged cords.
