In the immortal words of the Asian airline pilot, Sum Ting Wong, I think there is something else at play here. Function 551 is extremely limited as to what can be dialed out by the system. Numbers and routes have to be programmed in 551 and restrictions do apply. Since ESI does not have any function for DISA, I would look at anything else connected to the lines that may be shared with the ESI. If there is no programming in function 551, and there are no trunk to trunk out dials in the AA, then no one can dial out of the ESI.
