****** ADDITIONAL INFORMATION ******

extension.conf can support extension in macro:

[macro-stdexten];
;
; Standard extension macro:
;   ${ARG1} - Extension  (we could have used ${MACRO_EXTEN} here as well
;   ${ARG2} - Device(s) to ring
;
exten => s,1,Dial(${ARG2},20)                                   ; Ring the interface, 20 seconds maximum
exten => s,2,Goto(s-${DIALSTATUS},1)                            ; Jump based on status (NOANSWER,BUSY,CHANUNAVAIL,CONGESTION,ANSWER)

exten => s-NOANSWER,1,Voicemail(u${ARG1})               ; If unavailable, send to voicemail w/ unavail announce
exten => s-NOANSWER,2,Goto(default,s,1)                 ; If they press #, return to start

exten => s-BUSY,1,Voicemail(b${ARG1})                   ; If busy, send to voicemail w/ busy announce
exten => s-BUSY,2,Goto(default,s,1)                             ; If they press #, return to start

exten => _s-.,1,Goto(s-NOANSWER,1)                              ; Treat anything else as no answer

exten => a,1,VoicemailMain(${ARG1})                             ; If they press *, send the user into VoicemailMain

The contents of the macro go into the "s" extension of the generated context.

If you want to have other extensions, use the "catch" construct; see the wiki at:

http://voip-info.org/wiki/view/Asterisk+AEL2#Macros

catch a {
              VoiceMailMain(${ext});
              return;
      }

In your example:

 t => {
       goto s|1;
   }
   i => {
       goto s|1;
   }

would be:

  catch t {
      goto s|1;
  }
  catch i {
      goto s|1;
  }

Also, here would be a good time to translate your other code into something
a bit more readable in AEL:

  switch(${QUEUESTATUS})
  {
     case JOINEMPTY:
          ....
          break;
     case FULL:
          ....
          break;
     case TIMEOUT:
          ....
          break;
     default:
          ....
          break;
  }

In general, you can usually replace almost every goto with something else in AEL. Avoid goto as much as possible. That's not an AEL constraint, it's just
good programming.

Good luck, and I hope you enjoy your AEL experience! You might (re)read the WIKI AEL2 page, it's the best reference right now.

I wish all bugs were as easy to resolve!
