Many calls through it are purely digital too, but the phone signal is just the payload here - like the CDATA in XML. I'm interested in the framing, the fact that you request services from your phone keypad, from the basic dialing to putting calls on hold and so on. > Even more importantly, the signal is analog and interpreted by humans > rather than computers (most of the time).

More and more of the traffic on the phone network is IP over PPP :-) But I'm really more interested in the control interfaces to the phone system itself - the voice is just payload. > However, XML isn't designed to solve these problems.

But the phone network is made of computers. For every international phone call, lots of computers, made by different companies, running under different administrations in different cultures indifferent countries, talking over various different interconnects, conspire to create the illusion of a call going through.
