Call Conference
(Three-Way Calling)
Call Conference (also referred to as Three-Way Calling or TWC) allows you to add
another party to an existing call. This feature can be used whether you have
received or have placed the first call.
You cannot conference two incoming calls. You must initiate the second call in
order to activate Call Conference.
Call Transfer
Call Transfer is a voice call feature that allows you to transfer a call to a third party.
This feature can be used whether you have received or have placed the first call.
Table 2
How to Use Call Conference
How Do I Do This
Place a new conference call? While the first call is active, press and release the switch hook
button. The B channel LED light flashes to indicate that the first
call is on hold, and you will hear a dial tone. Then dial a third
party number.
After the third party has answered, press and release the switch
hook button to connect all three parties.
Drop the last party added to
the conference call? To drop the last party added to the conference call, press and
release the switch hook button.
Abort the second call and
switch back to the first call? If the dialed party is busy, press and release the switch hook
button to cancel the call and reconnect to the first call.
If you dialed a wrong number, or the far end does not answer,
hang up the phone to abort the attempted call. The phone will
then ring, indicating that the first call is on hold. Answer the
phone to reconnect to the first call.
What if I hear a dial tone
when I attempt to
conference all three parties? A dial tone indicates that one of the parties has dropped their
call. Press and release the switch hook button to return to the
previously active call. You can then conference a third party as
described previously.
What if the telephone rings
after I hang up? While you try to conference a call, the active call will be put on
hold to allow you to dial a new call. If you hang up the phone
before the call is connected, the telephone will ring to let you
know that you still have a call on hold.
