Macro( ) Calls a previously defined macro
Macro(macroname,arg1,arg2...)
Executes a macro defined in the context named macro-macroname, jumping to the s extension of that context and executing each step, then returning when the steps end.
The calling extension, context, and priority are stored in ${MACRO_EXTEN}, ${MACRO_CONTEXT}, and ${MACRO_PRIORITY}, respectively. Arguments arg1, arg2, etc. become ${ARG1}, ${ARG2}, etc. in the macro context.
Macro( ) returns -1 if any step in the macro returns -1, and 0 otherwise. If ${MACRO_OFFSET} is set at termination, this application will attempt to continue at priority MACRO_OFFSET+n+1 if such a step exists, and at n+1 otherwise. (In both cases, n stands for the current priority.)
If you call the Goto( ) application inside of the macro, the macro will terminate and control will go to the destination of the Goto( ).
; define a macro to count down from the specified value
[macro-countdown]
exten => s,1,Set(COUNT=${ARG1})
exten => s,2,While($[ ${COUNT} > 0])
exten => s,3,SayNumber(${COUNT})
exten => s,4,Set(COUNT=$[ ${COUNT} - 1 ])
exten => s,5,EndWhile( )
; call our macro with two different values
[example]
exten => 123,1,Macro(countdown,10)
exten => 124,1,Macro(countdown,5)
