NOTES:

For large companies, we recommend to maintain your own TFTP/HTTP/FTP/HTTPS server
for upgrade and provisioning procedures.

Once a “Firmware Server Path” is set, user needs to update the settings and restart the IP
Phone. If the configured firmware server is found and a new code image is available, the IP
phone will attempt to retrieve the new image files by downloading them into the SDRAM
of the phone. During this stage, the phone’s LEDs will blink rapidly until the
checking/downloading process is completed. Upon verification of checksum, the new code
image will then be saved into the flash. If TFTP/HTTP/FTP/HTTPS fails for any reason (e.g.
TFTP/HTTP/FTP/HTTPS server is not responding, there are no code image files available for
upgrade, or checksum test fails, etc.), the phone will stop the TFTP/HTTP/FTP/HTTPS
process and simply boot using the existing code image in the flash.

Firmware upgrade may take as long as 3 to 8 minutes over Internet, or just 1 minutes if it is
performed on a local network. It is recommended to conduct firmware upgrade in a
controlled LAN environment if possible.

Users are strongly recommended to download the binary files and upgrade firmware
locally in a controlled LAN environment.
