Does any one knows how to place a call from a shell agi? I guess is

While you can write an AGI in any language that has reasonable
STDIN/STDOUT facilities (fortran was a little bit frustrating), a shell
language like bash would not be my first choice.
Is there any reason you are not open to using a more 'mainstream'
scripting language like Perl or PHP? You'll find more people with that
experience willing to help.
My personal favorite is to use C because I know it best and because it is
a compiled language so your AGIs execute 'instantaneously.'
Whatever language you choose, use an established library for the AGI
protocol. Nobody gets it right the first time.
Algo how i get the dnid variable?
This implies that you need to read up a bit on the AGI protocol. The
second* thing an AGI should to is read the AGI variables -- one of which
is agi_dnid.
You can pass command line parameters to your AGI when you execute the agi()
function in your dialplan. For example:
exten = *,n, agi(my-first-agi,${AGENT-ID})
Your AGI can then access the command line arguments as you would
normally expect for a program executed from a shell -- $argv[1],
$argv[2], etc for PHP.
Personally, I dislike 'positional' parameters. I prefer to use the
getopt_long() function so my dialplan is 'self-documenting' and easier
to maintain so for me, the same command would look like:
exten = *,n, agi(my-first-agi,--agent-id=${AGENT-ID})
The difference is not all that apparent with a single parameter, but if
you have a half-dozen, it is much more obvious and once you've make the
change, you will always use it for consistency.
*) The first thing an AGI should do is set up a signal handler to catch
'SIGHUP' if the channel is hung up prematurely.
