Three way calling is incredibly useful and can simplify your life. To take advantage of this wonderful feature place your first call to one of the recipients. While on the first call, dial the 10-digit number of the second person. Press SEND. When you press SEND the first person is automatically put on hold while the call to the other recipient is made. When the second person answers, press SEND to create a conference call. Now you are connected to both recipients and have initiated a 3 way call. If the second person does not answer, press the SEND key twice to end the connection and go back to the first person. To end both conversations completely, press the END key.
