lua was nice but it was blocking ... no further dialplan processing before
it ends (at least this is what i went into)... and if it ends there is no
Callback to collect DTMF digits  :(
I tried to put it in background but i was not able to...

anyhow it was a nice experience ... my 1st lua scripting :)

ESL ... huh its really nice but not applicable to my application :( ... I
decided to go dialplan way and did everything within. honestly a separate
daemon than interacts with FS and decides what to do according to events
scares me a bit ... I have never done something like this and i was not
confident i would complete the task on time.

This means moving the logic outside FS... anyhow this is something on my
next ToDo list :)

to cancel the wrong destination number entry with a single # (* is end of
dial digit) starting from the point it asks you for the destination number
afterwards. This means you can cancel an while; getting destination number,
calls in being bridged, already bridged calls and return the A-leg call
state back to enter another destination.


As i didn't find any solution around here to do such a thing in dialplan or
via scripting i went down to the original code and wrote my own function.

BTW: Also, i will extend the function to do what it's name says "long". If
someone press # for a certain amount of time (topically 2 seconds) an action
will be triggered. If the duration is less than the specified time nothing
will happen.


Thanks for your e-mail.
