Direct Inward System Access (DISA)	Enter DISA authorization: Station view: Flags   Configure DISA: System settings	Call DISA number by DID.   Activate call forwarding for a station by means of a DISA procedure.   Call forwarding is activated for this station.
Intercept Conditions	Intercept / Attendant	Intercept no answer:   Seize the trunk and call any station in the communication system using DID.   The called station is switched to the intercept position or the call forwarding station in accordance with the ring cycle.   Intercept busy:   Set up an external or internal call from a station.   Use DID to attempt to reach this station via the trunk.   The call is either signaled at the intercept position or forwarded as entered in CM.   Intercept if incomplete or invalid number dialed:   Seize the trunk and use DID to dial any station in the system with an incomplete station number (for instance, omit the third digit in the three-digit DID number).   The call is routed to the intercept position.   Seize the trunk and dial a DID number that does not exist in the system.   The call is routed to the intercept position.   Intercept if no number dialed:   Seize the trunk and dial the communication system station number without a DID number.   After a timeout, the call is intercepted or released.
