Busy Override
Busy Override lets you join a conversation on a busy extension. It is
intended for high priority and emergency internal calls and requires a
special class of service. Ask your system administrator whether your
telephone has been assigned this class of service.
To break through
to a busy
extension ➩ Listen for the busy tone.
➩ Press the Busy Override (OVERIDE) key,
or dial # # 7.
You will hear the conference tone. Both
parties on the other end will also hear the
tone, and you will be joined in a three-way
conversation.
➩ Begin speaking. A single beep will sound
periodically until the overriding party
hangs up.
Note: Busy Override does not interrupt a privacy call or a telephone
in Do Not Disturb mode. (See “Do Not Disturb” on page 6-1
and “Privacy” on page 6-2.)
