Steve in correct in purely technical terms. Many PBX's have AIOD (Automatic Idenification of Outward Dialing) capability. The reason it is seldom used is refusal of the local phone companies to offer the service. Why? It lets the PBX vendor compete with Centrex. The phone companies boast about the billing info they can provide on Centrex stations, and use it as a marketing tool. They then refuse to offer AIOD to prevent equal capability to PBX vendors. The reason AIOD was developed was to let telco installed PBX's do this. I have fought this battle with Ohio Bell and GTE Ohio for over ten years. And now they are using E911 as another reason to buy Centrex. I have no problems with the telco doing this. They should be required to offer AIOD and DID lines tarrifed at reasonable prices as part of their Centrex offering, and not be allowed to set up a marketing advantage by denying these services. (Repeat of same argument applies to telco payphones and COCOT access lines: a level playing field should be required.) Macy M.
