now login to the http://yourip

and go update your modules in module admin leave the asterisk modules alone
i find loading all modules it gets messy just install what you need and process then install process
might have to do this a bit to get each module you want getting the requirements just right. beyond that then hit your apply button after you feel you have everything.

next secure it down with some iptables or scripts beyond the scope of this howto
