Enter the upgrade command into your browser’s address bar to upgrade firmware
on a phone. Use the following syntax:
http://phone-ip-address/admin/upgrade?protocol://server-
name[:port]]/firmware-path
• Protocol defaults to TFTP.
• Server name is the host requesting the URL.
• Port is the port of the protocol being used (for example, 69 for TFTP or 80
for HTTP).
• Firmware-path defaults to /spa.bin (for example, http://192.168.2.217/
admin/upgrade?tftp://192.168.2.251/spa.bin) for SPA phones and /
wip310.img for the WIP310. The firmware-pathname is typically the file
name of the binary located in a directory on the TFTP or HTTP server.
