672 Matrix ETERNITY NE System Manual
• The system checks whether the check box, Apply CDC to Internal Calls, is enabled in the CDC profile
assigned to either A or B.
• If the check box is enabled, CDC is applied on the call.
• Warning beeps are played to A, who made the call.
In this case the total time after which the call is disconnected will be 160 seconds (default CDC Timer) + 5 seconds
(Beep Timer; non-programmable) + 20 seconds (Goodbye Timer; non-programmable).
Feature Interactions:
• Call Transfer: In case of transferred call, the CDC timer gets reset and starts again afresh on the
transferred extension.
• Conference, Conversation Recording and Call Taping: CDC is treated as turned OFF.
• Call Park and Call Hold (Exclusive and Global): CDC is treated as turned ON.
• Interrupt Request, Barge-In and Raid: CDC is treated as turned 'ON'.
• Emergency Number Dialing: Emergency calls are not affected by this feature, i.e. CDC will not be
applied on the dialing of Emergency Numbers.
