DDI (DID) Day/Night Busy/Delayed Ringing
DDI Day/Night Busy/Delayed Ringing causes an incoming DDI call to a busy primary extension to
ring at a designated extension or extensions. DDI Busy/Delayed Ringing also causes an incoming
DDI call that is unanswered at a primary extension within a certain period of time, to ring at a
designated extension or extensions. Separate ring destinations are available for day and night modes.
DDI Busy/Delayed Ringing is also available for hunt group pilot numbers. However, when the
Queuing Timer expires, the call leaves the hunt group and is forwarded to the DDI Busy/Delayed
Ringing destination.
