This may be a dumb question, but do you have more then 1 PRI and or more then 1 carrier to your site. I am wondering, if your inbound DID are being ported 3 digits from 1 carrier and 4 or so digits from another carrier. When you dial the number, depending on what carrier your coming accross would depend on how your translations is being translated. Did you check command 7600 for the last 4 digit and so on to see if it might have a double DID assignment??? You have checked everything else that I would know of, for instance E600 cfwd all, E606 cfwd logout (if using IP phones), 5110 for DND destination, and 7600.
