[asterisk-users] Asterisk Automated Outbound Messaging

[Arturo Ochoa]

Sorry for my bad english,

I've developed a web interface for one of our customers, that allow them 
to create lists of telephone numbers, (even from excel files), and then 
a couple of scripts, one of them running on the background:
Script 1: Reads the file containing the telephone numbers and then 
creates .call files for each number, and then put all the .call files on 
a temp directory. You can start this process at any time. Even from a 
cron job.
Script 2: Every specific time checks the temp directory, and if it 
founds .call files, then it will copy the .call files to the outgoing 
asterisk directory, but only allowing, for example 5 .calls at the time. 
That way the asterisk only will let go 5 calls at the time. This script 
must be running on the background.

This is script 2:

#!/bin/bash
INTERVALO=10
tmp=/tmp/calls   #directory containing the .calls files
limite_canales=5   #number of simultaneus calls
asterisk=/var/spool/asterisk/outgoing
logger=/var/log/llamadas.log
fecha=`date`

function Generar_llamada {
        outgoing=`ls -1 $asterisk | wc -l`
        if [ "$outgoing" -eq "0" ] ; then
                echo "`date` No existen llamadas en este momento.. 
podemos incluir $limite_canales llamadas!!" >> $logger
                ls -1 $tmp > /tmp/lista_llamadas_totales
                tail -n $limite_canales /tmp/lista_llamadas_totales > 
/tmp/lista_llamadas
                cat /tmp/lista_llamadas | while read line
                do

                        mv $tmp/${line} $asterisk
                done


        fi

        if [ "$outgoing" -gt "0" ] && [ "$outgoing" -lt 
"$limite_canales" ] ; then

                let "extras=$limite_canales-$outgoing"
                echo "`date` Existen $outgoing llamadas en curso.. 
podemos incluir $extras llamadas" >> $logger
                ls -1 $tmp > /tmp/lista_llamadas_totales
                tail -n $extras /tmp/lista_llamadas_totales > 
/tmp/lista_llamadas
                cat /tmp/lista_llamadas | while read line
                do
                        mv $tmp/${line} $asterisk
                        echo "`date` Archivo $line fue movido a 
$asterisk" >> $logger
                done

        fi

        if [ "$outgoing" -ge "$limite_canales" ] ; then
                echo "`date` No existen llamadas Disponibles en este 
momento.. favor de intentar mas tarde!!" >> $logger
        fi

}

while : ; do

        call_files=`ls -1 $tmp | wc -l`
        if [ "$call_files" -gt "0" ] ; then
                 echo "`date` Comenzando con el procedimiento de 
generacion de llamadas..." >> $logger
                 Generar_llamada
        else
                 echo "`date` No existen cambios en el directorio $tmp" 
 >> $logger
                 echo "`date` A dormir por $INTERVALO segundos" >> $logger
        fi
sleep $INTERVALO
done


Hope it helps!
