	(if this function is allowed).

	extension does not allow Camp-on.

	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.

8	You can intrude on an ongoing call on a busy extension (if this
	function is allowed).
	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.
