A conference call is used to communicate simultaneously with multiple people over the phone. To set up a conference call: dial the phone number of the first person you want to invite to the conference call. Tell the person to hold. Press the More button on your phone followed by the Conference key. Then call the next person for the conference call. When he/she answers, tell the person that you are joining them to the conference call and press the Conference key to join them to the other caller. Repeat the process for any other callers you wish to add into the conference call.
