One of the challenges in the VOIP world these days IS call routing based on destination DID. It's easy to ship calls out trunks; it's far more compelling to send them to the destination PBX directly over UDP/IP. Sadly, the best mechanism anyone has come up with is manual number publishing in an rDNS style database, and the results are less than stellar... Nathan
