asterisk users - Jul 2009 - Goto from a feature macro is not working?

Hello,

I'm trying to implement multi-party calls according to these
instructions:

    http://www.voip-info.org/wiki/view/Asterisk+n-way+call+HOWTO

They are almost working, except that the Goto at the end of
[dynamic-nway-start] doesn't seem to work.  When I turn verbosity up a
bit, I get something like this in my error log:

    == Channel 'SIP/SWG-0085a180' jumping out of macro
'nway-start'

and then the SIP line is hung up, with no further dialplan steps
logged for that line.

Writing a small test case to see what's going on, I get the same
behavior:

    ; extensions.conf
    [macro-test1]
    exten => s,1,Goto(macro-test1a,s,1)
    
    [macro-test1a]
    exten => s,1,NoOp

    ; features.conf
    macro-test1 => *1,self/both,Macro,test1

When I activeate this feature with *1, I get:

    -- Executing [s at macro-test1:1]
Goto("SIP/SWG-007f9280","macro-test1a|s|1") in new stack
    -- Goto (macro-test1a,s,1)
  == Channel 'SIP/SWG-007f9280' jumping out of macro 'test1'

then nothing else about this (though the line isn't disconnected).

The documentation for Macro on voip-info.org seems to say that using
Goto from a macro is fine:

    http://www.voip-info.org/wiki/view/Asterisk+cmd+Macro

This is with Asterisk 1.4.26.

Any idea why this is happening, or any ideas how to work around it?

What I'm really looking for is an attended transfer where all three
parties are on the line together at the end, then the attending
operator can drop off when everything is confirmed.  Maybe there's an
easier way to do that?

Thanks!

----Scott.

Try replacing the "," with "|".  Shouldn't make any
difference, but it is a
future deprecation if I remember correctly.

I just ran into a similar problem, I needed a "macro" spreaded over 
several contexts because it's kind of a part of an IVR. I switched to 
GoSob() and Return() applications 
(http://www.voip-info.org/wiki/index.php?page=Asterisk+cmd+Gosub) and 
everything goes fine now. The only thing to be sure is that you Return() 
in *every* case from the Macro context(s), to avoid unknown and 
undesirable results of your calls.

Macro() won't work out of the macro context, if you Goto() away from the 
Macro() context, it will finish returning inmediately to the next 
priority where it was originally called, just like it's happening on 
your test call.

Finally that's one of the reasons why Macro() got deprecated in favor of 
the better GoSub() one.

Cheers,
