That is a good view, but in the meantime you'll have to make sure your
production servers keep running.
I use supervisor/sipsak as watchdog to restart if there is no kamailio
running.
kamcheck to start from supervisor, script keeps running if where is atleast 1
valid response every 3 tries (about 1 per sec). If 3 consecutive fails, stop
kamailio (which might fail) and then nuke it from orbit just to be save.
Script dies and supervisor will restart it, relaunching kamailio.
#!/bin/sh
err=0
/etc/init.d/kamailio start
while [ $err -lt 3 ]
do
sipsak -s sip:ping@127.0.0.1 2> /dev/null
if [ $? -eq 0 ]
then
err=0
else
err=$(( $err + 1 ))
date
echo error count: $err
fi
sleep 1
done
/etc/init.d/kamailio stop
killall -9 kamailio
