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) Maintaining the secrecy of passwords. c) Selecting passwords that are complex and random, so that they cannot be easily guessed. d) Changing passwords regularly. Conditions • This setting is required if "Trunk Security" or "All Security" is selected in [511] DISA Security Mode. • Each DISA security code should be unique. • The number of digits for DISA security codes is selected in [530] DISA Security Code Digits.
