Button with led configuration

Hello guys,

I have a customer who would like to use a button on his yealink to configure his dial plan on our platform. Basically an "open" and an "closed" button. When one of the buttons is pressed they want the led next to the button to be active so they know which dialplan is active.

The button itself to configure the dialplan on our platform is not problem, see underneath:
linekey.1.type = 13
linekey.1.line = 1
linekey.1.value = 915
linekey.1.label = Open
linekey.1.extension = <6>1<3>2

The problem with this is that I can't configure the led within a marco, you need a BLF or a BLF list key for that. So I have to change the entire key to a BLF with the same values and a macro to keep the led alive.

I have tried to read the Using Enhanced DSS Keys document and use the cfgGeneratorTool but i'm having trouble with this, so far i've got:

features.enchanced_dss_keys.enable = 1
edk.edklist.4.enable = 1
edk.edklist.4.mname = aan
edk.edklist.4.action = 915$Cp2$2$Cp2$2$$LEDg&Lon$


But it's not working.
Basically what i want is
1 button named "on" when pressed dials 915 and send the following code "wait 2 sec, select option 2, wait 2 seconds, select option 1" keep the led active

1 button named "off" when pressed dials 915 and send the following code "wait 2 sec, select option 2, wait 2 seconds, select option 2" keep the led active

I hope you guys can help me out.
