i know it has the same impact
im using asterisk since 0.4 yup lots of years mostly for the hobby and i
have written some stuff in bash and php  but never really got connected to
real programming. i read code no problem and understand exacttly what its
doing and do fix up what i need but most of the time just dont have the
patience to do it myself  (i have full time work in IT)

in this instance i was just writing a simple ivr maybe 10 lines were you
could descend down the ivr as long as there is a recording and if it could
be done simple within the dialplan i prefer that

i have made sophisticated ivr with lots up webservices and databases but
then i of course use a external language  (a function to speak to
webservices with xml parsing  i think would be a great addition to the
dialplan )

thanks
