During a restart, J100 Series telephones requests a series of files, using HTTPS or HTTP, from the configured file server. The various files, in the order that the phone requests them, are:

• J100Supgrade.txt

  Details the firmware supported by the IP Office system. Used by the phone to request those firmware files if necessary. If using theIP Office system as the file server, the file is auto-generated if not physically present. The file ends by telling the phone to request the 46xxsettings.txt file.

• 46xxsettings.txt

  Details the phone settings for various different models of supported phones including the SIP server settings. If using the IP Office system as the file server, the file is auto-generated from the system settings if no file is physically present.

  • Early releases of J100 firmware used a separate J100settings.txt file. Later releases changed using the 46xxsettings.txt. IP Office R11.0 and higher systems redirect requests for a J100settings.txt file to the 46xxsettings.txt file.

• FW_S_J129_R1_0_0_0_35.bin (example)

  This type of file is the phone firmware file. The file name indicates the particular model of phone the file is for and the release number of the firmware. If the phone downloads new firmware, the firmware upgrade takes up to 10 minutes. From IP Office Release 10.0 SP3 onwards, the supported firmware is part of the IP Office Manager for each release and is installed on the system as part of the upgrade process.

• WebRootCA.pem

  If using TLS, the phone requires an appropriate certificate downloaded from the file server.

• Language .XML Files

  The settings file will indicate if the phone should request any language files. If using the IP Office system as the file server, for IP Office Release 10.0 SP3 onwards, the file is auto-generated from the system settings if no file is physically present.
