ASTERISK PBX

I need a asterisk distro compiled, preferably on a Solaris platform. BSD or Linux would be second choice. This distro would need to include a web based management console. The whole Idea is to strip everything away from the OS that is not needed to run Asterisk and its management console. I also want this distro to be as minimalistic as possible. One thing that has to stay however is the accounting interface. I need to see how many minutes each user spent on the phone and whole they were on the phone with. IE the telephone number I also want to be able to filter this by calls made dialed and received and time or any combination there of. These reports need to be exported as csw files and must be downloadable. Other than that I need all the core asterisk functionality, including being able to see witch extentions are registered and wich arent as well as trunks. This is the basic scope of the project, although things might change as we go along. One thing to keep in mind is that we need the lightest possible version of asterisk.
