EXP40 Problem

[imfloridaguy]

Since upgrading a client's T46G phone to V80, on the EXP40, we've lost the red led when a call is parked. Prior to the upgrade, when a call is parked, it lit the red led on the corresponding button on the EXP40.
Now, it does not.

The led IS WORKING properly on the T46G.
The led IS NOT working properly on the EXP40.

In my office, I have tested this with another T46G and EXP40.
In my office it DOES WORK, but at my client's site, it DOES NOT work.

The only difference I can find is that the client's EXP40 shows an older firmware than the one in my office.

Client's site:
EXP40 1 Hardware Version - 66.0.0.0
EXP40 1 Firmware Version - 6.16.0.0

My office:
EXP40 1 Hardware Version - 66.0.0.0
EXP40 1 Firmware Version - 7.16.0.0

In autoprovisioning, this is being used:
features.blf_led_mode = 1

Can you help?
