Why not AGI?

They both ('shelling out' or calling an AGI) have the same 'impact' on 
system resources.

You can even write an AGI in shell if you lack the skills for other 
languages like C, PHP, or Perl.

You should be able to cobble up an AGI in PHP (or Perl, but I'm not much 
of a Perl coder myself) just by cutting and pasting from some of the 
examples on voip-info.org.

This simple task would be a great way for you to 'get your feet wet.'

What will you do if the file is not available?
