Line Key LED vs BLF LED?

[uberdome]

How do you configure the line keys to show similar LED colors to BLF keys?

Specifically, I'd like to see:

• Green - Registered, on hook
• Red Flashing - Ringing
• Red - Off hook
  

This seems to be the standard behavior for BLF LED Mode 0, which is very similar to old Cisco SPA behavior (which is what we're familiar with).

It would also be very nice to show when registrations have failed. Cisco shows this with an orange LED. Perhaps a slow red flash or alternating red and green would reveal that quickly.

I cannot seem to find how to make the standard line keys light up this way.

Thank you, Chris
