Outgoing Calls

Busy Extension

You call an extension and receive busy tone.

Camp-on

You can notify a busy extension of your call by sending a call

waiting tone (if this function is allowed).

4 Press to camp-on.

Keep handset off hook. When the called extension replaces the

handset, it will be called automatically.

Notes: If you receive the busy tone again, the desired

extension does not allow Camp-on.

The number for Camp-on may differ from country to

country, see table “Alternative Programming for Camp-on,

Automatic Callback, Call pick-up, Intrusion” on page 90.

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.

Notes: If you still hear the busy tone, 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 Camp-on,

Automatic Callback, Call pick-up, Intrusion” on page 90.

Diverted Extension

See chapter “Bypass Call Forwarding” on page 50.
