You can notify a busy extension of your call by a muted ringing call
(if this function is allowed). 4
Press to camp-on.
Stay off hook. When the called extension replaces the handset, it
will be called automatically.
Note: If you receive the busy tone again, the desired
extension does not allow Camp-on.
The number for busy extension may differ from country to
country, see table “ Alternative programming for Automatic
Callback, Camp-on, Intrusion ” on page 106.
This function is also accessible using the off hook menu
“Camp on”, see section “ User busy tab ” on page 27.
Intrusion
You can intrude on an ongoing call on a busy extension (if this
function is allowed). 8
Press to intrude.
Intrusion tone is heard and a three-party call is established. When
the called extension replaces the handset and you keep off hook,
the called extension will be recalled automatically.
Note: If you still hear the busy tone, then your extension
does not have the authority to intrude or the desired
extension is protected against Intrusion.
The number for intrusion may differ from country to country,
see table “ Alternative programming for Automatic Callback,
Camp-on, Intrusion ” on page 106.
