Misdialed Numbers
If you do not want to complete dialing, or if you misdial a number, either

number.

Reaching a Busy Destination or an Extension with Do 
Not Disturb Activated
If the called destination is busy or the extension has Do Not Disturb 
activated, the display will show “Busy” or “DND” on the DST line.
In both cases, your options for handling the call are the same, except for 
the Callback option, which only applies when calling a busy destination.
To handle a call to a busy destination or an extension with Do Not 
Disturb activated:
• Press [S
OURCE] to return to the caller requesting the transfer.
• Press Cancel to disconnect the destination so that you can dial a new 
one.
• Press Release to camp the caller on to the busy destination or 
disconnect the source. (For an explanation of camp-on, see page 86.) 
If the transfer is not allowed, you will hear a beep tone and “CANT” will 
show on the display.
• Press [O
VERRIDE] to break into the busy extension. For more 
information on using Override, see page 36.
• Press [S
END MSG] to send a message waiting indication to the called 
extension. For more information on Message Waiting, see page 35.
• Press [C
ALLBACK] to receive notification when the destination is free.
If you reach a busy extension or you are placing an outside call and all of 
the trunks are busy, you can request an automatic Callback. The system 
monitors the line and rings the console when the line becomes free. When 
you answer a Callback at the console, the top line of the display will show 
“CALLBACK.” Callbacks on outside calls are used when all system trunks 
are busy, not when the called party is busy.
