Establishing a Conference Call 61
■
For a blind conference, press Feature + 430 immediately after you
dial the number. You return to the conference, and you and the
second party hear the called party’s telephone ringing.
If the third party answers, three parties are now in the conference call.
If the third party is internal and does not answer, the attempt to
conference that party is cancelled. You cannot establish a conference call
with an NBX user’s voice mailbox.
4 Repeat steps 2 and 3 to conference in a fourth party.
■
On a 3101SP Basic Telephone, you can press the button to activate
speaker phone operation.
■
You can turn off the microphone or the mouthpiece on the handset
by pressing the
button (3101, 3101SP). The other parties cannot
hear you, but you can hear them.
■
For details about the Speaker and Mute features, see “Telephone
Buttons and Controls” in Chapter 2 for the 3101 and 3101SP Basic
Telephones.
Disconnecting the
Last Person
That You Called
Use the Conference Drop feature to disconnect the last person that you
add to a conference call. This feature is helpful if, when you add a party,
your call is answered by someone else.
■
Only the person who added the last caller to the conference call can
drop that caller.
■
Your administrator can configure any Access button on the Attendant
Console to be a Conference Drop button.
On a 3Com 2101 Basic Telephone or a telephone that does not have a
button programmed for Conference Drop:
1 Press Feature + 431.
2 The system returns you to the others who are in the conference call.
