Transferring Phone Software, Application, and Media Files
3.9.3 Phone Application
The firmware for the phone can be updated by downloading a new software file to the phone.
If an incorrect software image is being attempted to be loaded onto the phone, the phone will
reject the request and return to normal operation without reboot. As part of this security mech-
anism, new software binds are identified by a "Supported Hardware Level" information built into
the header.
Prerequisite: The phone knows it’s own hardware level (from the part number and/or by a dy-
namical check of its HW level).
When a new software bind is downloaded to the phone, the following verifcation is performed:
1. If new software bind has hardware level header included (in the bind header): Hardware
level of new bind is compared with phone’s hardware level.
• If compatible (or if Override is set): Proceed with update
• If NOT compatible: Abandon update and return to original application
2. If new software bind does NOT have hardware level header included (in the bind header):
Software version of new bind is compared with minimum known supported SW level.
• If compatible (or if Override is set): Proceed with update
• If NOT compatible: Abandon update and return to original application
3.9.3.1 Upgrade Using File
Use an image file choosen by browsing to upgrade the phone.
3.9.3.2 Upgrade Using FTP/HTTPS Access Data
If the default FTP/HTTPS access settings (see Section 3.9.2, “Common FTP/HTTPS Settings
(Defaults)”) are to be used, Use defaults must be set to "Yes", and only the Filename must be
specified.

Do not disconnect the phone from the LAN or power unit during software update. An
active update process is indicated by blinking LEDs and/or in the display.
