OptiPoint 600 SIP - Updating firmware

The phone can be converted from HFA to SIP by updating to the SIP firmware. Maybe the way back works, too ;-)

The firmware seems to consist of three parts, that can updated more or less independently

Application (op600sip.app) - Under some conditions the op600sip file has to be renamed to vxworks.app
Phone device software (inca.h86)
Platform device software / bootrom (bootrom.app)


The update the firmware, follow the following steps (from the release notes):

With the necessary files present in the download folder, the device upgrade can be initiated either from the device, the Deployment tool or the Webserver.
Setup an FTP server (free 3CDaemon i.e.) which matches with User and Password to the FTP client of the phone, found in: Touchscreen (Arrow up) Service â?“ Administration â?“ File Transfer â?“ Downloads â?“ Download Server Settings (With 3CD FTP server the Account Name is not mandatory.)
Touchscreen (Arrow up) Service â?“ Administration â?“ File Transfer â?“ Downloads â?“ Download Software
Be patient, download and SW install of the phone takes time.
И для конфигурирования с Asterisk, см:
