Firmware upgrade won't stick
I am trying to upgrade the firmware on my 46t phone from 28.71.193.8
to 28.73.193.45. It goes through the install and download, but the old firmware still shows up. these are new phones.

RE: Firmware upgrade won't stick
It is possible it upgrades and then downgrades... is it attached to any PBX yet?
