With all of this discussion about AOSs (and while I'm writing nasty
letters to the three Arizona hotels I stayed in recently :-) ), could
someone please explain to me exactly where AOSs are in the sequence
of a telephone call?

I presume that when I make a long-distance call from a hotel, the
call goes straight through the hotel switchboard and out to the AOS.
How am I doing so far? Are the AOSs necessarily local, or might the
call go a ways even before it heads for the recipient?

Then, how does it get from the AOS to the callee? I presume that
the AOS somehow routes it to one of the standard LD carriers. Does
each AOS use one particular carrier, or might they choose from
all of them depending on the distance the call needs to go, time
of day, etc.?

Thanks!
