T46S/T46G show green icon (blf) although phones disconnected (Asterisk)

[jobst]

Hi

A little annoying problem: other phones show GREEN icon (BLF) although phones are NOT connected or NOT registered.

I prefer if the icon was RED when the phone is NOT available.

All phones have latest firmware.
All of my phones are connected to an Asterisk (latest version) server.

The Asterisk server correctly states that phones are UNAVAILABLE in both "core show hints" and "sip show subscriptions" when NOT connected or registered. The Astrisk server also shows state correctly when phones are idle/busy/call etc.

Phones show states correctly if a user is BUSY and/or RECEIVING a call by either FULL RED and FLASHING RED, this is good!

In Features->General Information I have set "BFL LED Mode" to "1".

What's annoying is phones showing "green dot user icon" EVEN if the phones are NOT present/registered/connected.

I want to see a RED icon, so people know "don't ring phone is not connected".

How can I achieve this?
Thanks.
