Actually, it does seem to - when you strip lots of detail away a key 
question seems to be the architectural choice of "end system knows 
where it is and tells the dispatcher" vs "infrastructure expected to 
know where the thing using it is". Interesting that both VoIP and 
cellular tech are apparently pushing the architecture towards a more 
e2e model.
