I have a few Polycom IP320 and 321 phones that work fine and registered through TFTP.
There are about a dozen that are either stuck in a reboot loop stating "image not compatible with phone"
Or one 320 that displays it’s MAC and IP only.
I’ve tried to create new templates that don’t have a firmware in the settings, doesn’t change anything.
Tried to download a newer firmware from Polycom and put it in another slot in a new template, nothing changes.
Can’t realy connect to the web interface of the phone as i either get a message that the page cannot be displayed or the phone reboots.
