Updating the software
VoIP is a technology that is changing rapidly. Shipping
phones with a fixed set of functionality makes them a
bad investment. Customers expect free software up-
grades when additional features are available and
known problems are fixed.
For this reason, after initializing the settings, the
snom100 checks for new software releases. This is
done in three steps:
1) First of all, the file located in the setting
“firmware_status” is downloaded on the
phone. The setting may contain an http or a
tftp URL. Loading this small file avoids big
network traffic, usually these files are below
500 bytes. The firmware_status setting is not
available to the user; however it may be con-
trolled through the network setting mecha-
nism. This allows operators to take control of
the update frequency and the software revi-
sions.
2) It compares the given boot loader URL with
the URL that has been stored with the last up-
date (in setting “bootloader”). If it differs, the
user is prompted for acknowledgement and
the new boot loader is loaded from the web
