Three-way conference calls
You can set up a three-party call by using two lines at the same time. You
can also join an intercom call with a call on an outside line. The outside line
call must be established first, because an intercom call cannot be placed on
hold.
1. Make or answer an outside call.
2. Press HOLD and call someone on another line, or start
an intercom connection.
-OR-
Call someone on another line, or intercom someone and
the line is put on hold automatically.
3. When this call is answered, press CONF. The three-party
conference begins immediately.
• To talk privately with one external party (two-line conference only):
1. Press HOLD to place both lines on hold.
2. Press a LINE key to talk privately with the person on
that line.
3. Press Conf to resume the conference call.
• To talk privately with one internal party (two-line conference only):
1. Press INT to talk privately with the person on
that handset and place the external line on hold
automatically.
2. Press Conf to resume the conference call.
• To drop one line:
Press the LINE key for the party you want to keep. The other line is
dropped.
