If your station is in Do Not Disturb (DND) mode, internal, external and transferred calls do not ring 

your station and Off-hook Call Announce calls are denied. You can continue to make calls while in 

the DND mode. When originating a call in DND mode, you will hear a short burst of interrupted dial 

tone followed by continuous dial tone. You can start dialling at any time during either tone.
If you put your Primary extension into DND mode, all calls to that telephone are rejected. If your 

extension is set for Call Forward-Busy or Call Forward-Busy/No Answer, the call is redirected to the 

forwarding destination immediately. 
If you put an extension other than the Primary extension into DND, only calls to that extension on 

your telephone will be blocked. Appearances of that extension on other telephones continue to ring.
