Firmware files

Once the phone has received the Setting Server URL, it will also try to fetch its firmware file(s). A firmware file is used to configure which firmware version the phone should use.

In order for the phone to automatically install the firmware update version according to the firmware file, setting update_policy must be set to "auto_update".

<update_policy perm="RW">auto_update</update_policy>

If the setting file(s) have not set the parameters "firmware_status" or "firmware", the phone will try by default to fetch the firmware file using two specific URLs that it creates using the given Setting Server URL and the phone type.

Examples:

If the provisioned Setting Server URL is http://example.com/test.xml , a P820 phone will try to fetch the following firmware file:

• • http://example.com/gigasetP820/gigasetP820-firmware.htm
  • in case file "http://example.com/gigasetP820/gigasetP820-firmware.htm" was not found, the phone also tries to fetch: http://example.com/gigasetP820-firmware.htm
    

If the setting file(s) have set the "firmware_status" or "firmware" parameters, the phone will only try to fetch the URL configured by these parameters - see Firmware Update via Auto-provisioning for more details on how to use these parameters.
