I've installed and got a running asterisk 13 from debian distribution.
Added asterisk-gui and got that to sort of work but getting frustrated with what looks like sip/nat issue and that I couldn't find a way to be able to call between local extensions.
It's mainly for personal use, I wanted a simple PBX that could handle a small group of sip devices that could call each other and that could use an external SIP gateway.
The aim was to have better sound quality over dodgy networks then what I was getting from [login to view URL]
And that bit seams to work nicely when I call like the voicemail, but haven't been able to make a single call... rings, but no sound at pickup :(
I probably cold do with a couple hours of help from someone who well know the beast.
