WARNING
There is a risk that fraudulent telephone calls will be made using the Trunk-to-Trunk Call feature of
DISA.
The cost of such calls will be billed to the owner/renter of the PBX.
To protect the PBX from this kind of fraudulent use, we strongly recommend:
a) Enabling DISA security (Trunk Security or All Security).
b) Keeping passwords (verification code PINs/extension PINs) secret.
c) Selecting complex, random PINs that cannot be easily guessed.
d) Changing PINs regularly.
• Hardware Requirement: An MSG card
• DISA Delayed Answer Time
It is possible to set the Delayed Answer time so that the caller will hear a ringback tone within a
preprogrammed time period first before hearing an outgoing message (OGM).
