NEWBEE here
Just happen to find this discussion on virtual PBX.
I have installed on and old server a demo version of 3CX
A VOIP-PBX for your own lan hosting.
I used an old PC as a server, and Grandstrem IP phones.
The total cost was about 1200$s.
www.3CX.com clearly the cheapest and very versatile, and easy to configure.
