3.10.1 Configuring Automatic Update of Firmware and Configuration File
The IP phone offers a built-in mechanism for automatically upgrading its software image and
updating its configuration. This method is used to upgrade the phone firmware and update its
configuration, by remotely downloading an updated software image and configuration file.
The automatic update mechanism helps you keep your software image and configuration up-to-
date, by performing routine checks for newer software versions and configuration files, as well as
allowing you to perform manual checks.
The automatic update mechanism is as follows:
1.
Before connecting the phone, verify that the provisioning server is running and that the
firmware and configuration files are located in the correct location.
2.
Connect your phone to the IP network, and then connect the phone to the power outlet.
3.
During DHCP negotiation, the phone requests for DHCP options 66/67/160 to receive
provisioning information. The DHCP server should respond with Option 160 providing the
provisioning URL or options 66 and 67 providing the TFTP IP address and firmware file
name respectively.
4.
The phone then checks whether new firmware is available by checking the firmware file
header. If the version is different from the one currently running on the phone, the phone
downloads the complete image and burns it to its flash memory.
5.
If a new firmware is unavailable, the phone then checks whether a new configuration is
available. If a configuration file is available on the server, the phone downloads it and
updates the phone’s configuration after verifying that the configuration file is related to the
phone model and the version is later than the current one. When configuration update is
needed, the phone reboots.
Notes:
•
In the DHCP Discover message, the phone publishes its model name in
Option fields 60 and 77 (e.g. 320HD). If the administrator wants to provide
different provisioning information to different phone models, the
administrator can set up a policy in the DHCP server according to the phone
model name.
•
If the phone for some reason is powered off during the firmware upgrade
process, the phone is unusable and the recovery process must be
performed (refer to Section
3.10.3
on page
46
).
•
You can only use firmware files with an
img
extension and configuration files
with a
.cfg
extension.
•
To “force” the firmware or configuration file to be retrieved immediately
regardless of the “Check Period” value, click the
Check Now
button.
•
An additional auto-provisioning mechanism is supported if the provisioning
environment does not provide all the required information (e.g. DHCP
options). For more information, refer to the document
3xxHD Advanced
Support for Auto-provisioning Application Note
