Busy Override

Busy override allows you to join a conversation on a busy extension

number. It is intended for high priority and emergency internal calls

and requires a special COS. Ask your system administrator if your

telephone has been assigned this COS.

Note:

Busy override does not interrupt a privacy call or a telephone

in do-not-disturb (DND) mode, unless you have a DND

override class marked in your COS.

Break through to a busy extension number as follows:

1. Listen for the busy signal.

2. Dial .

3. Listen for the override tone; both parties on the line also hear the

tone. You are joined in a three-way conversation.

4. Begin speaking. A single beep tone sounds periodically until the

overriding party hangs up.
