Automatic Callback Busy (Camp-On)
Description
The system calls back the extension user when the called party or the selected CO line becomes
idle, if this feature was activated beforehand.
Automatic Callback - Extension
If the extension user answers the callback ringing, the called extension (previously busy)
automatically starts ringing.
Automatic Callback - Trunk
If the extension user answers the callback ringing, the designated CO line (previously busy) is
automatically selected for making a CO call.
Conditions
• If the callback ringing is not answered in four rings (within 10 seconds), this feature is
cancelled.
• The extension user can cancel this feature by dialling the feature number for "Automatic
Callback Busy Cancel."
• More than one extension user can set this function to one extension or CO line at the same
time.
• FWD / DND Override
Call Forwarding or Do Not Disturb feature does not work for the callback ringing. It always
rings the extension on which this feature was activated.
