I think your terminology isn't far off, and quite clear.
Going back to the Asterisk box, that has no effective limit on the number
of registrations. I have six on mine, and a block of DDIs that come in
and are nicely separated. I also having incoming analogue on it, and that
too is separated. I can call out on any of them. It's certainly worth
