T46G/T48G BLF Not working on newer firmwares

[keffa]

I have just installed the T46G in six client sites and can confirm this is occurring with latest firmware. I have noted that phone state BLF (I.e. ringing, busy, available) using BLF type 0 seem to work OK but if a phone is disconnected, the BLF lamp still remains on, even after multiple re-starts. In fact, under the right conditions (Set up the BLF, turn the phone off, turn it back on and voila), the BLF lamp will show a steady green for a extension that does not even exist!
