Up-to-date how to guide

Can anybody point me in the direction of an up-to-date how to guide?

I really just want to make a purely IP SIP PBX and although I have found lots of guides, I havent been able to get anything working.

I am looking at building a system and build all other parts on to (IM and presence) but before i get anywhere near that i just want to talk between two softphones over IP?

Pointers anybody?


Have you checked out any of the guides listed here?


There are quite a few guys on how to start setting things up.
