Branch Gateway supports Trivial File Transfer Protocol (TFTP) downloading of configuration files and firmware files for IP phones. TFTP can be used to download image files, upgrade scripts, and settings files to IP phones. The local TFTP server stores the files and supports requests to read files from the outgoing directory for phone images and scripts.
Note:
TFTP server support is available only for IPv4.
You can use CLI procedures for downloading the files for IP phone upgrade from the Branch Gateway TFTP server.
