This really depends on your requirements / features: I would suggest that you compare between ? Trixbox ? Elastix ? PBX in a Flash ? AsteriskNow If you need larger implementations, and have time to read great documentation check out ? Freeswitch or ?

I believe 2.8.0.3 is the current stable build, but I'm running 2.8.0.1 on my server with no issues.
