Problem as follows:

[default]
exten => 777,1,Gosub(sub,1,1)
exten => 777,n,Hangup()
exten => h,1,NoOp(hung up in ‘default’ context)

[sub]
exten => 1,1,NoOp(in sub)
exten => 1,n,Playback(tt-monkeys)
exten => 1,n,Return()
exten => h,1,NoOp(hung up in ‘sub’ context)

This works fine if the caller listens to all the ‘tt-monkeys’ and let’s
the system hangup. You get the hang up in the ‘default’ context.

But, if the caller hangs up BEFORE the end of ‘tt-monkeys’ – the hang up
occurs in the ‘sub’ context. This means that I have to force each sub
routine to go to the main contexts ‘h’ extension (‘exten =>
h,1,Goto(default,h,1)’ in this case).

Is there a way to tell * to use the default ‘h’ extension on a hang up –
rather than having to put a ‘h’ in to every separate sub routine?

I know Tilghman said “…Gosub, on the other hand, isn’t really even
executing at that point, so there isn’t a code path that exists whereby
the Gosub can empty the return stack and return to the original
place….” [see
http://lists.digium.com/pipermail/asterisk-dev/2008-May/033153.html].

But what does that mean in English ;)?

Thanks

  • Well a solution for you to put original context name in variable and then
    use that variable in goto statement on h.

  • Thanks for your reply – but I did it a slightly different way:

    “Nevermind – I’ve re-written my dialplan so that all subs are in one
    context. Now I only need 1 more line of code.”

    Thanks anyway 🙂
