not too go against the freeswitch crew, especially since I agree you 
should probably update. (just backup fs first).

I am not sure of the performance implications running fs like this (-nf) 
but you can do something like (and this it's quite a nasty hack):


#!/bin/sh

PREFIX=/usr/local/freeswitch

stop() {
	local count=0
	kill -9 `cat /var/run/freeswitch_loop.pid` > /dev/null 2>&1

	while [ $count -lt 10 ]; do
		[ $count -gt 0 ] && sleep 5
		count=`expr $count + 1`
		pidof freeswitch > /dev/null && killall freeswitch || count=100
	done

	return $?
}

start() {
	while true; do $PREFIX/bin/freeswitch -nc -nf > /dev/null 2>&1; done &
	echo $! > /var/run/freeswitch_loop.pid
	return 0
}

case "$1" in
	start) start ;;
	stop) stop ;;
	restart) killall -HUP freeswitch;;
	reload) killall -HUP freeswitch;;
	
esac

exit $?
