Automatic Callback Busy (Camp-on)
If a dialed extension or a desired CO line is 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.
The caller can alternate the alerting method, either ring or 
voice, when making an intercom call.
On the other hand, any extension can set the alerting 
method, either ring or voice, when receiving an intercom call.
Ringing (Default): You can call the other party with a 
ring tone.
Voice-Calling: You can talk to the other party 
immediately after confirmation tone.
If the called party uses a single line telephone or portable station, Voice-Calling is not 
available.
This feature is not available when the called party's telephone is in the Voice Call Deny mode.
