[Asterisk-Users] simple perl-agi - where's the error?

Hello!

I'm trying to setup a perl-deadagi, but my perl skills lack. can
someone tell me why the following code doesn't work:

#!/usr/bin/perl
use Asterisk::AGI;
 $AGI = new Asterisk::AGI;

$dialstring = $AGI->get_variable("DIALSTRING");
$res = $AGI->exec("DIAL $dialstring");


the asterisk output says:

AGI Rx << GET VARIABLE DIALSTRING
AGI Tx >> 200 result=1 (089324154332)
AGI Rx << EXEC DIAL  ""
    -- AGI Script Executing Application: (DIAL) Options: ()
Mar 20 11:46:02 WARNING[21970]: app_dial.c:773 dial_exec_full: Dial
requires an argument (technology/number) AGI Tx >> 200 result=-1
    -- AGI Script agirouter/dialscript.pl completed, returning 0


so the get_variable-command seems to work, also the exec(with
"$dialstring = 089324154332" the call goes out), but not setting the
variable. should be so simple :-( astcc-agi seems to use the same
syntax, so i have no clue what is wrong in my place... 
any ideas? thx!

kind regards
christian

Try setting it to sth like SIP/200 instead of a single number.

You should try '$res = $AGI->exec("DIAL",
"$dialstring");'

[Asterisk-Users] simple perl-agi - where's the error?

the DIALSTRING you were given is just an extension, 089324154332.  As 
Lenz pointed out, and it also says in the app_dial.c:773 WARNING, it 
must be technology/number, not just a number.  Not sure perl methods, 
but you might concatenate a technology before the number, something like
$res = $AGI->exec("DIAL Local/$dialstring");
or
$res = $AGI->exec("DIAL SIP/$dialstring");

again, I don't know perl, so if that broke something, sorry ;)

I believe the problem was that the expected value of $dialstring in the
Perl script wasn't making it back to *.

I would recommend a little debugging:

#!/usr/bin/perl
use Asterisk::AGI;
$AGI = new Asterisk::AGI;

$dialstring = $AGI->get_variable("DIALSTRING");

# Debug here:
print STDERR "\$dialstring contains '$dialstring'\n\n";
# This _should_ print to the console on the Asterisk server

# Note also the minor changes to the arguments for exec method:
$res = $AGI->exec('DIAL', $dialstring);


What you want to do is make absolutely certain that you are getting what
you expect with the $AGI->get_variable("DIALSTRING") call.  If you
get
only a phone number then you WILL need to add the technology to the exec
call:

$res = $AGI->exec('DIAL', "ZAP/g1/$dialstring");
-or-
$res = $AGI->exec('DIAL', "SIP/$dialstring");

(Use the technology appropriate for your application.)

Quickie Perl lesson: Putting a variable in double quotes causes
interpolation.  For example, if the variable $dialstring contains a
phone number (e.g. 5595551212) then the command:
$res = $AGI->exec('DIAL', "ZAP/g1/$dialstring");

Becomes the equivalent of:
$res = $AGI->exec('DIAL', "ZAP/g1/5595551212");
