As stated in the FAQ „How can I update a snom phone?”, it is possible to configure your
snom phone with config files, which consist of the following settings.
This release v3.4 is describing firmware settings beginning with version 3.4 ! In case you
are using an older firmware version please refer to v2.0 of this document.
Phone
settings
Settings are non-volatile name/value pairs that are stored in the flash of the phone. They
include registration information, dialled 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 files are ASCII-based files 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 file 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 file looks like this:
<html>
<pre>
#This is a settings file
#
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 to get configuration
information from anywhere in the world. The location of a file 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 flash 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 (e.g.
http://www.snomag.de/snom200/snom200.htm) provided. For a small description of
