asterisk users - Nov 2015 - Find me macro - calling multiple people to get a hold of one

Hi list,

We're trying to set up a phone number that customers can call to get a hold
of anyone of a group of sysadmins (and not their voice mails!). We found the
findme example ([1]) that makes the callees press 1 to accept the call. It
almost works, but it doesn't work correctly when one of the callees, the
sysadmins, hangs up after accepting the call.

We're using this 'screen' macro:

=============================[default]
exten => _9999XXXXXXXXXX,1,Dial(SIP/bla/${EXTEN:4},40,M(screen))
exten => _9999XXXXXXXXXX,2,Hangup

[macro-screen]
exten => s,1,Wait(1)
exten => s,n,Background(press-1)
exten => s,n,WaitExten(10) ; the value is the Wait time before we assume the
call is not accepted
exten => 1,1,NoOp(Caller accepted) ; Do not set MACRO_RESULT to anything to
connect the caller
exten => t,1,Playback(weasels-eaten-phonesys) ; if you're too late with
pressing 1
exten => t,n,Set(MACRO_RESULT=CONTINUE)

[findme]
exten =>  s,1,Set(CALLERID(all)="Alarm" <911>)
same  =>   n,Playback(please-wait-connect-oncall-eng)
same  =>   n,Dial(LOCAL/9999${WIEBE_MOBILE})
same  =>   n,Playback(vm-nobodyavail)
exten  =>  t,1,Playback(vm-nobodyavail)
============================
First of all, what is MACRO_RESULT? I can't seem to find anything about
that. Googling for it yields basically nothing.

But the biggest problem is when the callee answers, then hangs up. The person
calling is connected to the phone that hangs up, instead of hearing
'vm-nobodyavail'. This seems to be because there is nothing that sets
MACRO_RESULT in that event (it's only set on 't', timeout).

I tried adding:

exten => h,1,Verbose(0,"The callee hung up")    
exten => h,n,Set(MACRO_RESULT=CONTINUE)

to handle the hangup (h), but it's not doing that.

WaitExten() pushes the result back on the stack and restarts the context, right?
So what is the result when the person hangs up?

Regards,

Wiebe

Sorry, but why is a simple

Dial(SIP/A&SIP/B&...,${CALLTIMEOUT},${DIALOPTS})
...
Hangup()

not acceptable? If necessary, one can try to find out which devices are
technically available to
avoid dialing a non-existent device. If pressing a "1" is acceptable,
then why not pressing the
"DND" to not accept the call?

Because when somebody has their phone off, the caller gets a voicemail
immediately.

It appears that [1] lucked out in that it may sometimes work. WaitExten()
doesn't work in a macro and has no option to supply the context it runs in.
The '1' extension defined there is never called.

You can use Background() instead, but you have to play something that is long
enough so people have time to press a button; then you don't need
WaitExten(). Background() has documented behavior with regards to macros. It
calls extensions in the calling context, except if you give the context as
option:

  exten =>
s,n,Background(emergency&lines-complaining-customers&press-1&press-1&press-1&press-1&press-1&press-1&press-1,,,macro-screen)

But then still, more problems. The 1 and 4 extensions work, but 2 doesn't;
it hangs up. I really don't get that.

====================================  exten => 1,1,Verbose(0,"1
pressed")
  exten => 1,n,NoOp(Caller accepted) ; Do not set MACRO_RESULT to anything to
connect the caller

  exten => 4,1,Verbose(0,"4 pressed")
  exten => 4,n,NoOp(Caller accepted) ; Do not set MACRO_RESULT to anything to
connect the caller

  ; This doesn't seem to work. It goes to hangup, in the default context
  exten => 2,1,Verbose(0,"2")
  exten => 2,n,Set(MACRO_RESULT=CONTINUE)
====================================
And I still have the problem that if I hang up instead of pressing 1, the caller
gets connected to that disconnected line. There doesn't seem to be any
extension I can put in my macro that responds to the hangup. Not e (exception),
i (invalid), h (hangup), etc.

Normally, Background() restarts the current context with the result on the
stack. But when you hang up, it just SEEMS to return with a non-zero exit code,
yet not continue with the 's' extension. Is it possible to make it
continue with the dial plan?

I got it working. I set the MACRO_RESULT to CONTINUE in the start extension, and
then set it to something else when I don't want to connect the caller:

[globals]
WIEBE_MOBILE = 10digitnr
ANOTHER_MOBILE = 10digitnr

[default]
exten =>
_9999XXXXXXXXXX,1,Dial(SIP/sip2phoneprovider/${EXTEN:4},40,M(screen))
exten => _9999XXXXXXXXXX,2,Hangup

[macro-screen]
exten => s,1,Set(MACRO_RESULT=CONTINUE) ; default action -> not connecting
exten => s,n,Wait(2)
exten =>
s,n,Background(emergency&lines-complaining-customers&press-1&press-1&press-1&press-1&press-1&press-1&press-1&press-1&press-1&press-1&press-1&press-1&press-1,,,macro-screen)
exten => 1,1,Verbose(0,"1 pressed")
exten => 1,n,Set(MACRO_RESULT=SANTA)

[findme]
exten => s,1,Set(CALLERID(all)="Bla" <123456789>)
same  =>   n,Playback(please-wait-connect-oncall-eng)
same  =>   n,Dial(LOCAL/9999${WIEBE_MOBILE}&LOCAL/9999${ANOTHER_MOBILE})
same  =>   n,Playback(vm-nobodyavail)
exten => t,1,Playback(vm-nobodyavail)
