I’ve just bricked one of my polycom ip330 phones when i decided to format the filesystem and forgot that i didnt have a provisioning server. All i wanted to do is reset the phone and get the webinterface working again. This is not something you can do from the phone interface but only with a provisioning server.
Good thing there is a way to get it working again.
Polycom has a special provisioning server online just for bricked phones on http://voipt2.polycom.com/
On the phone during startup you choose SETUP, drill down to Server Menu and select. Change server type to HTTP, server address to 188.8.131.52/406 Now, change the dhcp menu, change Boot server to Static. Exit and save. The phone will reboot and will start updating.
