Ring Again on Busy gives a caller the opportunity, afterencountering a busy Directory Number (DN), to ring the DN again when itbecomes free. If a dialed DN is busy, or if all the trunks are busy, pressing theRing Again key asks the system to monitor the dialed DN or trunk. When itbecomes available, the system notifies the caller. The call is automaticallydialed again when the caller presses the Ring Again key a second time.Ring Again on No Answer is applied to the originally dialed DN only.
