Seize an outside (CO) line before dialing the outside phone number. • WARNING There is a risk that fraudulent telephone calls will be made using the Outside-toOutside (CO-to-CO) Line 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 DISA security codes secret. c) Selecting complex, random codes that cannot be easily guessed. d) Changing codes regularly. • If you dial 4 digits or more when dialing an extension number, the call will be disconnected. When you dial an invalid extension number of 3 digits or less, the call is redirected to the preprogrammed intercept destinations or disconnected, according to system programming. • CO-to-CO Line Call Duration The length of outside-to-outside (CO-to-CO) line calls may be limited through system programming. Both the outside caller and the outside destination will hear a warning tone 15 seconds before a specified time limit. When the timer expires, the call is disconnected. 76 Operating Manual
