I have a network that connects 2 households and would like to setup a simple voip server so that I can call between the houses.
It needs to be for ubnutu , I have used the free 3CX system and while it works brilliantly it doesnt support linux and I can get a windows box.
The users will never need to call external lines. They will only make 'calls' between laptops/pc.
Can someone please make a recommendation and maybe even a tutorial that I can follow
