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 CBX 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 6–3 and “Privacy” on page 6–4.)
