this may help you out. haven't done the server hookup before though it has been suggested.
anways, looks like the cta100 hooked up to a server will do the trick for you. read this as it should enlighten what you are up against. this is an older document and i'll try to dig up something newer off the partner site. this group has a manual online so figured it would be easier than trying to email you one.
