L’objective de ce teste est déterminer l’impact de l’envoi des paquets SIP NOTIFY (avec event : keep-alive), dont le but est de garder le port sur le routeur NAT des clients ouvert, sur l’utilisation du CPU dans le serveur Astrad.
Script
#! /usr/local/bin/bash
for user in `mysql -uUSER -pPASSWORD asterisk -BN -e "select username from location3"`; do
asterisk -rx 'sip notify nat '$user
echo "-Sending NOTIFY to $user"
done
echo "Done";
