As stated in the FAQ „How can I update a snom phone?“, it is possible to congure your
snom phone with cong les, which consist of the following settings.
Phone settings
Settings are non-volatile name/value pairs that are stored in the ash of the phone. They
include registration information, dialed numbers, network settings and other information that
should be available after rebooting. Settings can be made read only on a per setting basis.
This is useful in environments where an operator sets up the phones and wants to avoid users
changing settings that affect the stability of the phone. In this way, expensive trouble ticket
searching can be reduced and the total cost of ownership of the phone be minimized.
Settings Files
Setting les are ASCII-based les containing lines (terminated with newline or carriage
return/newline pairs). Comments start with a # or a < character. The < and > characters allow
easy integration of html tags. Names may consist of the characters a-z, A-Z, 0-9 and _.
Appending a name with an “!” character means that this setting becomes writable by the
user. Appending the name with an “&” states that the setting is read only (this is the default).
If a setting is marked writable, the value in the settings le is only written to the phone if
that setting has not yet been set up at the phone. In order to overwrite such settings, do not
append the setting name with “!”.
A sample le looks like this:
<html>
<pre>
#This is a settings le
#
phone_name: testphone
dns_domain: intern.snom.de
dns_server1!: 192.168.0.9
</pre>
<html>
Downloading procedure
Settings are downloaded from web servers. HTTP is a very powerful way of getting
conguration information from anywhere in the world. The location of a le is described as a
URL, i.e. it begins with http://.
This is how the Settings are set up:
1. The settings that were stored in the ash memory are read.
2. Network and DNS is set up. This allows the phone to get settings from internet URLs.
3. It then checks the setting “setting_server” and loads the settings stored in the URL

provided (e.g. http://www.snomag.de/snom200/snom200.htm). For a short description
of the le format, see below. The setting_server URL can also consist of a {mac}
statement like http://www.snomag.de/snom200/snom200.php?mac={mac}. The MAC
address is a unique identication ID of Ethernet devices. snom devices have the form
000413xxxxxx, where xxxxxx is a hexadecimal number identifying the snom device.
The phone automatically replaces the MAC address with its own mac address before
using the URL. Phone-specic settings can therefore be provided for each phone via
this mechanism. The “setting_server” setting can be set manually via webinterface or
automatically via DHCP (options 66 and 67) and through snom4S SIP proxy.
4. The de facto settings are added. These settings may differ from what has been set up
because DHCP may have changed them. The settings include:
• the IP address of the device,
• the net mask,
• the IP gateway,
• the hostname,
• the DNS domain, rst and second DNS server,
• the UTC offset in seconds,
• the time server,
• DHCP on or off
Each setting is described by its ‚Name:‘which should be added to the cong le followed
by a colon and its specic value. Name is followed by ‚Valid values:‘ where the valid values
are described. Each possible value is bracketed in <>.The brackets must be left out if you are
using the values stored in a cong le. ‚Default:‘ shows the value which is set by default after
you have removed all of the settings with a manual update or reset values! Lastly, ‚Description’
gives brief details of each setting. See also the snom4S SIP proxy manual for PNP conguration
via the proxy.

[ F REQUENTLY A S K E D Q U E S T I O N ]

used; the username and the password can usually be set up on the proxy and registrar.

Valid values: e.g. <kitchen>

Default: blank
Description: H.323 URL ID assigned to the phone.
gkgw_mode
Valid values: <auto>, <gatekeeper>, <gateway>, <none>
Default: auto
Description: Gatekeeper or gateway mode. Can be <auto> (automatic discovery of
Gatekeeper) or <gatekeeper> for explicitly using the gatekeeper mode, <gateway> for
gateway mode and <none> for autonomous operation.
h323_gateway
Valid values: e.g. <192.168.0.9>, <gtk.company.de>

12 snom technology AG
[ F REQUENTLY A S K E D Q U E S T I O N ]
Con guring snom phones for Mass Deployment 13
[ F REQUENTLY A S K E D Q U E S T I O N ]
frequent refreshes of registration but also cause additional network trafc. Very high values
result in large intervals of disconnection from the Gatekeeper before getting back online if
the gatekeeper reboots without sending any un-registration request to the phone.
early_start
Valid values: <true>, <false>
Default: true
Description: The early start option allows the H.245 channel to be set up earlier, and
hence speeds up the call setup. When early start is turned on, the H.245 channel address
is also supplied in the Setup message. This speeds up the call because the H.245 channel
negotiations can proceed in parallel to H.225.
fast_start
Valid values: <true>, <false>
Default: false
Description: Fast start sends encoded OpenLogicalChannel messages within the Setup
messages and hence eliminates the need for a separate H.245 channel for Codec capability
negotiation. This will only work if the other party is also supporting fast start. This feature
in H.323 is optional, meaning it can be ignored by an endpoint not supporting this feature,
hence making the snom phone revert to the normal H.245 signaling on a separate channel.
Note that if Fast Start is being used, Out of band DTMF might not work because the DTMF
info is relayed on the H.245 channel.
h323_h245_tunneling
Valid values: <true>, <false>
Default: false
Description: H.245 Tunneling option sends tunneled H.245 messages within an H.225 pdu.
This also accelerates connection setup if both parties are supporting this feature.
trace
Valid values: <true>, <false>
Default: true
Description: Enable tracing output of the current protocol stack.
h323_h450
Valid values: <true>, <false>
Default: false
Description: If ag is set to <true>, H.450 supplementary services are used, otherwise
(<false>) it is facility-based.
Gateway prexes (H.323 only)
external_line_prex
Valid values: e.g. <0>, <111>

12 snom technology AG
[ F REQUENTLY A S K E D Q U E S T I O N ]
Con guring snom phones for Mass Deployment 13
[ F REQUENTLY A S K E D Q U E S T I O N ]
Default: blank
Description: Prex used for reaching outside numbers via an H323 gateway. This prex
will be replaced by the gateway_prex in a dialed number for calling outside numbers (see
gateway_prex).
gateway_prex
Valid values: e.g. <*5>
Default: blank
Description: Prex with which an ISDN gateway is registered at the gatekeeper. The phone
will replace this prex with the external_line_prex in a dialed number if it is starting with
the external_line_prex (see external_line_prex).
Hence the user doesn’t have to dial numbers like 5*1234567 but can instead dial 01234567
with the same effect.

key_seq_hold_on
Valid values: e.g. <*1>

Description: Key code that is sent by the phone to the PBX if it is set and the “Xfer” key is
pressed on the phone for a blind transfer.
key_seq_transfer_consultation
Valid values: e.g. <*6>
Default: blank
Description: Key code that is sent by the phone to the PBX if it is set and the “Xfer” key is
