Callback Request
Callback Request can help you complete calls to 
extensions that are busy, ringing, or in Do Not Disturb 
mode, once those extensions become available. It lets 
you hang up and have the CBX call you back with 
triple rings under the following conditions:
• when a busy extension you are trying to reach
becomes free
• when a ringing extension you are trying to reach is
used again and then becomes free
When you then answer, the CBX automatically dials 
the number.
While you are queued for a callback, the status light 
beside your Callback (CALLBCK) key is on.
