We have built an Allstar Hub, Node and had fun with it. It is a well designed and functional system. The one to many node features is what makes it shine along with the voice quality. Unlike IRLP, other nodes can connect to your node, and when you move your node to connect to somebody else's node...guess what ....all nodes connected to yours go along for the ride. Very nice feature, but one you have to keep in mind when connecting to others nodes.
I have failed to document all my adventures and setbacks and will have to circle back on my notes to do any justice to AllstarLink. I have them somewhere, I promise.
Another day....it is work in progress.
