[Asterisk-Users] AGI ?

[Jon Scottorn]

Hi All,

   I have been attempting to get an AGI LCRdialout script to work.
Basically what I need to have happen is when someone dials out a number
the script check to see if it is local if so, go out the ZAP channel. If
the ZAP channel is busy, go out the IAX channels, if IAX is all busy, go
out the SIP channels.  Here is a sample of what I have in my script.  


#!/usr/bin/perl

use strict;
use Asterisk::AGI;

my $callerId = "MyNumber";
my $log = "/var/log/asterisk/dialout.log";
my $gIaxUser = "MyIAXPROVIDER";
my $gIaxPass = "MYIAXPASS";
my $gIaxHost = "myIAXHost";
my $gSipHost = "MYSIPHost";

my $AGI = new Asterisk::AGI;
my $gDialedNo = shift;
my $gNumber = "";
my $gPrefix = "";
my $gAreaCode = "";

### Sets Outbound CallerID ###
$AGI->set_callerid($callerId);

open(LOG, ">>$log") or die("Couldn't open $log\n");

### prefix, and number and assigns it to the num array ###
my @num = parseDialed($gDialedNo);
if(!@num) {
        ### Log Statement for Troubleshooting ###
        #print LOG "(". localtime() .") ERROR: Number not Valid!\n";

        ### If num is empty DIE ###
        return -1;
} else {
        ### Otherwise grab the items from the array ###
        $gNumber = pop(@num);

        }
        ### Final catch all for invalid number ###
        return $dialStr;

Can someone give me some advice as to how to get a channel status of
what the $AGI just dialed.


Thanks in advance,
