The Mitel SX-200 and SX-100 and SX-2000 have AIOD capability. This is still available, but nobody uses it ... it's basically an obsolete protocol. It was included in the products because telcos wouldn't buy a PBX that could not support AIOD. It was used mainly for Centrex CU type services. I'm told there are some telcos with an AIOD tarriff still on the books. Not so here. Most of the modern CO's are the same way ... they can do AIOD due to telco specs, but never install or implement the feature. Macy M.
