Verification tone.

Press.

You are called back if the extension finishes the ongoing call or the

next time the extension finishes a new call. You have to answer

within eight seconds otherwise the Callback service is cancelled.

Busy Extension

You call an extension and receive busy tone.

Intrusion

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.
