I'm thinking of writing an article about running out of area codes. Does anybody know of sources I could speak to?

I know this must seem too obvious, but why not stop issuing gobs of
subscriber numbers to PBXs? If my company has 30 incoming lines, all
hunting to each other, and disappearing into a big black box anyway so
they can't be reasonably identified from one another, -- do I need
thirty DIALABLE numbers assigned to me? One will do, and in my local
CO, the switch can say to itself: "There's got to be a xxx-xxxx around
here somewhere I can connect this call to." Of course the other
circuits would have identifiers for tracing and troubleshooting and
all that, but the public network doesn't need to know about how many
circuits there are, only the local CO. Usually, these extra numbers
aren't listed anyway.
I realize this plan falls flat for Centrex-type direct inward dialing
services, but (sorry telcos) this isn't the majority of use (at least
not yet?).
My guess is that it would free up at least 30% of the dialable capacity
nationally, and closer to 50% in metro areas (like Atlanta;-).
Comments? ( <-what a stupid thing to ask, but it's 3am.).
