Good Morning: I have three Polycom 550 telephones that have lost power momentarily and are now in an endless boot / reboot cycle. When I do catch the phones in between booting / rebooting, I am able to momentarily log into the web gui of the phone to see what is going on. Unfortunately, the phones reboot before I can reprogram them via the web gui. I have tried to reset the phones via the endpoint manager, but they are not taking. Any ideas?
