T46G Firmware 28.80.0.60 disables the intercom auto-answer function

I have tested on 4 different phones now all hardware version 28.2.0.128.0.0.0. When using the intercom between the phones on firmware version 28.80.0.60 the phones just ring. I downgraded the phones to firmware version 28.73.0.50 and they all auto-answer the incoming intercom as expected again.

Any time table for this to get fixed?
