 Automatic Callback Busy
You can set the telephone to receive callback ringing: 
when a dialed extension becomes idle.
when your desired CO line that is in use by another extension becomes idle.
You cannot set Automatic Callback Busy for a busy party outside of the PBX.
When you answer the callback ringing:
For an outside call: The line is seized.
For an intercom call: The called extension starts ringing automatically.
To set (for both extension and CO line)
To answer the callback ringing from an idle extension
To answer the callback ringing from an idle CO line
If you do not answer the callback ringing within 10 seconds, this feature will be canceled.
