Since I started with 3CX-PBX (actually version ) I'm trying to bring up my Yealink T48S to the actual firmware (66.82.0.20). As soon as I start the pgrade, everything stucks, the phone restarts an stays on the welcome screen (Initializing - waiting...) for hours. It's not possible to start the phone anymore.
When I reset the phone to factory defaults and reprovision it, everything works again! But I can just get to firmware version 66.81.0.110 where everything is still working, but the phone is marked as unsupported!
Is there any known bug in this new firmware or is there any setting on the phone that has to be changed for this new firmware v82?
Thanks for any help.
