Busy Extension Callback 
If a called extension is busy, you can set a busy extension callback. When the busy 
extension becomes free, your phone will ring. When you pick up the handset, the 
other extension will ring for the user to answer your call.   
 
1.    When you hear a busy signal, press the programmed 
[CBK] button, or dial [4][4] or press the soft button  
corresponding to the CBK option on the LCD   
panel. 
 
 
2.    When you hear the confirmation tone, replace the   
handset. 
 
 
3.    When the called extension becomes free, your phone 
rings. The ‘CALL BACK’ message will appear   
on the LCD panel.     
 
 
Lift the handset to ring the free extension and wait for it   
to answer. 
 
 
 
4.    To end the call, replace the handset or press either   
the [Speaker] or [End] button. 
 
 
 
 
If you don’t answer a callback within 30 seconds, it will be cancelled.   
 
You can have a maximum of five callbacks set on extensions at any one time.
