## Busy extension

You call an extension and receive busy tone.

#### Camp-on

You can notify a busy extension of your call by a muted ringing call.

Press (see display).

Keep the handset 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.

#### Intrusion

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

Press (see display).

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, your extension does not have the authority to intrude or the desired extension is protected against Intrusion.
