Mitel 5220 BLF Busy Lamp

Has anyone had any luck configuring the 5224 or the 5220 with busy lamp? I have the 5330 and that one has an option to configure the buttons with a Speeddial + BLF and it works but the 5224/5220 even with the lastest firmwire do not have the Busy lamp option. Is there another way to configure it?

Thanks for the help.


I’ve been trying to get the busy lamps working too. Did you ever figure it out?
