2 T46G Phones; Different BLF behavior

[phoneguy797]

I have 2 T46G phones, where I have BLF DSS buttons defined to monitor the status of other phones on the system.

What I noticed is that one of the T46 phones, on the BLF buttons, show solid GREEN lights when the monitored phones are Idle, and solid RED lights when the monitored phones are InUse. (Which to me is reminiscent of the T38 behavior)

On the other T46 phone, the BLF buttons are 'Off' when the monitored phones are Idle, and are solid RED when the monitored phones are InUse.

I thought it was because the phones were different revision (one was version 71 and the other was version 72). I upgraded both of them (and a T42G also on the same system) to 28.72.0.1, but the behavior remains the same- one with the GREEN Idle lights, and the other with 'Off' Idle status lights. [BTW, the T42G behaves as I expect a T4x phone to behave- that the Idle BLF buttons LED is 'Off', not GREEN]

It doesn't matter to me which way the lights are when Idle, whether they are 'Off' or solid GREEN, I'd just like the 2 same-model phones to behave the same!?! At this point I can't explain the difference to the customer.

The DSS buttons are programmed the same on both phones- BLF, value 221 (to monitor x221 for instance), Account 1

I can't figure out why one would show GREEN and the other would show 'Off'
