That's why I don't understand and asking here. :-)

I see. Thanks for clarifying! In short there is no 'extra' extension
for 'hangup' like 'failed'.

Thank you! I will try this! Is local redirection have any
performance/resource hit on calls?

I see. Therefore Dial is executed within my context and I have
extension 'h' for it. Tricky.

Do I really need this? Because extension 'h' is executed on hangup so
this is redundancy I think.

So I don't need NoOp for _X.. Right?

Many thanks for your informations!
