To upgrade the phones’ firmware in batch via auto provisioning, ask the distributor for
the firmware file, upload it to the provisioning server, and then specify the access URL in
configuration files.

## Configure the access URL of the firmware file ##

firmware.url =
For example, enter “tftp://admin:password@192.168.1.100/2.72.0.1.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”.
