I didn't call the number. I keep getting told that it a dedicated DSL line and it shouldn't have a number attached to it. Maybe it was just tagged with one for labeling purposes? It not only doesn't have dial tone, it starts ringing right away as if you dialed a number when you go off hook. I don't know who services the switch, it's a Mitel at a Holiday Inn. The recording is from the LEC. I disconnected it from the switch.
