Asterisk 11 match destination extension in macro

Question

Long story short: Fanvil phones don't allow you to change microphone volume (that is too low).

I've created this custom macro, but cannot match the case the phone (exten 131) is receiving a call, it work only when it make a call:

[macro-fanvil]
exten => s,1,NoOp(catch: callerid: ${CALLERID(num)} - exten ${EXTEN}- ${CHANNEL})
;exten => _131,n,Goto(receive)
exten => s,n,GotoIf($[${EXTEN} = 131]?receive)
exten => s,n,GotoIf($[${CALLERID(num)} = 131]?:iscalling)
exten => s,n(iscalling),NoOp(alzachiamante: ${CALLERID(num)} - ${CHANNEL})
exten => s,n,Set(VOLUME(RX)=10)
exten => s,n,MacroExit
exten => s,n(receive),NoOp(alzaricevente: ${CALLERID(num)} - ${CHANNEL})
exten => s,n,Answer()
exten => s,n,Set(VOLUME(TX)=10)
exten => s,n,MacroExit

This is from console:

 -- Executing [s@macro-fanvil:1] NoOp("SIP/195-00000096", "macro-fanvil: callerid: 195 - exten s- SIP/195-00000096") in new stack
 -- Executing [s@macro-fanvil:2] GotoIf("SIP/195-00000096", "0?receive") in new stack
 -- Executing [s@macro-fanvil:3] GotoIf("SIP/195-00000096", "0?:iscalling") in new stack
 -- Goto (macro-fanvil,s,4)
 Executing [s@macro-fanvil:4] NoOp("SIP/195-00000096", "alzachiamante: 195 - SIP/195-00000096") in new stack
 -- Executing [s@macro-fanvil:5] Set("SIP/195-00000096", "VOLUME(RX)=10") in new stack
 -- Executing [s@macro-fanvil:6] MacroExit("SIP/195-00000096", "") in new stack

It seems that ${EXTEN} is always the one that is calling, how can I catch the event of the 131 is the destination of the call?

As you can see ${EXTEN} inside a Macro is always s.
-- Executing [s@macro-fanvil:1] NoOp("SIP/195-00000096", "macro-fanvil: callerid: 195 - exten s- SIP/195-00000096") in new stack

You have to tell the Macro the ${EXTEN} when you calling it.
This is normally done with...
https://wiki.asterisk.org/wiki/display/AST/Macros
...at...
Calling Macro with arguments
...where the Argument from the calling Channel/Context is outputed in: Verbose()

Long story short: You have to change your Macro to check the Argument

[macro-fanvil]
exten => s,1,NoOp(catch: callerid: ${CALLERID(num)} - exten ${ARG1}- ${CHANNEL})
;exten => _131,n,Goto(receive)
exten => s,n,GotoIf($[${ARG1} = 131]?receive)
exten => s,n,GotoIf($[${CALLERID(num)} = 131]?:iscalling)
exten => s,n(iscalling),NoOp(alzachiamante: ${CALLERID(num)} - ${CHANNEL})
exten => s,n,Set(VOLUME(RX)=10)
exten => s,n,MacroExit
exten => s,n(receive),NoOp(alzaricevente: ${CALLERID(num)} - ${CHANNEL})
exten => s,n,Answer()
exten => s,n,Set(VOLUME(TX)=10)
exten => s,n,MacroExit

...and call it with Argument: Macro(fanvil,s,1,(${EXTEN}))
