RESULT1=$(/usr/sbin/asterisk  -rx "dongle show device state $MODEM1" | grep Registration |  /usr/bin/awk '{print $5}' |  /usr/bin/sed 's/,*$//')
RESULT2=$(/usr/sbin/asterisk  -rx "dongle show device state $MODEM2" | grep Registration |  /usr/bin/awk '{print $5}' |  /usr/bin/sed 's/,*$//')

if [ "$RESULT1" != "Registered" ]; then
/usr/sbin/asterisk  -rx "dongle restart now $MODEM1"
echo "Chip-claro1 restartado" >> /var/log/checa_modens
echo "$(date '+%d-%m-%y %H:%M:%S')" >> /var/log/checa_modens
echo ============================== >> /var/log/checa_modens
echo " " >> /var/log/checa_modens;
fi
if [ "$RESULT2" != "Registered" ]; then
/usr/sbin/asterisk  -rx "dongle restart now $MODEM2"
