If you need to get through to a busy extension, you can inform the exten-
sion that there is a call waiting. Call Waiting is indicated either by a tone
(if the busy extension is an analog phone extension), or as a second call
(if the busy extension is a digital system phone or an IP phone).
Note: If the called extension does not accept Call Waiting signals, you
will continue to hear a busy tone. If the busy extension ignores
the Call Waiting tone, you can order callback.
Whether an extension can initiate or receive a Call Waiting indication is
controlled by a category, which is set by the system administrator.

To cancel Call Waiting, tap .
6.2.4 Intrusion
Depending on the authorization of your extension, you can get through
to a busy extension using the Intrusion feature, which connects you to
the ongoing call after a short tone burst.
If intrusion is not allowed for the called extension, you will continue to
receive busy tone.
Before the intrusion is performed, a warning tone is sent to the parties in
the ongoing call. As long as the three parties are connected, you will
hear a warning tone.
Note: The warning tone can by categorization be disabled, both before
and during the intrusion.
To intrude on an ongoing call at a busy extension, do the following:
H.323 Phones
Tap Intrusion.
SIP Phones
Press the numeric key 4.
6.2.5 Bypass
If you need to get through to a certain extension currently being
forwarded by follow-me or external follow-me, you can bypass the exten-
sion. This requires that you have a category for bypass. There are two
ways to order a bypass, by an extension or by assistance.
