Sounds very cool. Have you thought about marketing it to other companies? I'd say there's a very good living to be made deploying this sort of thing in smaller companies. The "bang per buck" from Asterisk and VOIP is amazing compared to traditional pots phones and a hardware pbx. Check out

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
