A while back at one of our meetings, the question was raised as to how
to use a terminator digit for entering PINs or other things in Asterisk.
Just so happens I was faced with a similar problem today and solved it
using a few functions and some variable math in Asterisk like this:
exten => _X#,1,Goto(${EXTEN:0:$[${LEN(${EXTEN})}-1]},1)
Ugly, ugly ugly but that's the way it's done.
I don't know off hand how long those features have been available in
Asterisk but they were added some time in 1.2.
Regards,
John
