When I want to get rid of nf_conntrack_sip, I add these lines to 
modprobe.conf

install nf_nat_sip /bin/true
install nf_conntrack_sip /bin/true

It's program independent, so you don't have to mess with other 
configuration files.
Just tired rmmoding h323 helpers, adding
install nf_nat_h323 /bin/true
install nf_conntrack_h323 /bin/true
and restarting shorewall. The modules aren't loaded
