Do Not Disturb !4
DND allows you to temporarily block and discontinue ringing from incoming CO calls and intercom calls. You can
activate DND while your telephone is idle or busy. Some extensions with higher Class of Service may override an
extension’s DND condition. Also, UCD Group ringing overrides extension DND.
When you have activated DND, you will hear a special intercom (stutter) reminder tone when you lift the handset or
use the speakerphone. If you have assigned a button on your digital speakerphone specifically for DND, that button
will light whenever you activate the feature.
