the firmware file, upload it to the provisioning server, and then specify the access URL in
configuration files.

firmware.url =
For example, enter “tftp://admin:[email protected]/2.72.0.1.rom” (“admin” is
replaced by the authentication user name and “password” is replaced by the
authentication password) in the “firmware.url =” field. During the auto provisioning
process, the phone connects to the provisioning server “192.168.1.100”, and downloads
the firmware file “2.72.0.1.rom”.
