Some PBX's have DISA's set up as just an inbound number to receive
dialtone from the switch.  If no access code is required, no
*authorization* need be given.  This is why some switch owners have
discovered huge toll charges to various drug-producing nations on
their phone bills.

One excellent reason to requirsome type of access code on your DISA,
and to turn off or change DISA numbers regularly.
