This section provides information about how the Distinctive Ringing feature behaves in certain circumstances. Use this information to ensure that you receive the maximum benefits of Distinctive Ringing under all conditions. The following considerations apply to Distinctive Ringing:

• If Distinctive Ringing is disabled, the system generates a one-burst repetitive tone for all incoming calls. The one-burst repetitive tone is useful for equipment that is interfaced by analog lines, especially if you use an off-premises telephone. A single distinctive ring cycle is used for each new incoming call to an off-hook telephone or headset. The system alerts a Callmaster^® terminal with a single ring cycle whenever either the headset or the handset is plugged into the headset jack.
