Well it just goes to show the internet is the ultimate ‘pipe’ from one thing to another. And in this case, people who collect legacy phone systems (yes they do exist, the people not the phones, I mean the phones of course they exist!) wanted a way to interconnect their various switches and sets to eachother.
So it’s cool, they’ve established a wold wide network, collaborative net, or C*NET.
Which reminds me, one of these days I want to do a multi-site asterisk deployment with speex as the back end haul and see how that goes.
