7.7 SW
loading
The software to be loaded into the phone is to be stored on a web server
with HTTP protocol. This web server is called SW server in the menus
and in this document. The following files are stored on the SW server:
d42x02-applic_R1A.dat
(CAA 158 0043) The application firmware for the DBC 42x 02
phones. R1A in the file name is an example.
d42x02-boot_R1A.dat
(CAA 158 0044) The boot ROM firmware. This software is used to
be able to load the application into the IP phone. R1A in the file
name is an example.
d42x02-config.txt
(CAA 158 0042) The configuration file. This file contains informa-
tion about the version of the software to be used and other config-
uration data. Normally the configuration file has to be adapted for
each installation, see the description for
CONFIGURATION FILE
FOR DBC 42X
.
d42x02-lang_R1A.txt
(CAA 158 0045) The language file containing all the languages that
are supported. R1A in the file name is an example. See the descrip-
tion for
LANGUAGE FILE FOR DBC42X 02
.
When the IP phone is powered up, the phone fetches the configuration
file from the SW- server. If the software version defined in the configura-
tion file is different than the software version in the phone, the phone
fetches the application software file and/or the boot ROM software file
from the SW server. The new software is automatically stored into the
flash memory in the phone.
It is possible to load both newer and previous software versions with this
method.
To check the software version in the phone, see 7.25 Software version
on page 63
7.8 Several
configuration
files
A certain group of IP phones can often have different characteristics
compared to the other groups of extensions concerning which codec to
use, domain names, emergency number data etc. The following
methods exist to get different configuration files for the groups of
phones:
•
Use the DNS (Domain Name Service) domain name received from
DHCP, 7.11.2 Data from DHCP on page 30.
