Just talking to either different computers or talking via two interfaces into the same system but with different information being fed in. That's what happens when decisions are made by computer, they do what they're told, alas they're usually instructed by committee and programmed by disinterested people with their minds elsewhere.
Perhaps I've spent too much time in the I.T. industry...
Phone them up and get to talk to the same system through a third interface, might as well go the whole hog.
