Instructions for Conference:
From the conversation with Party A press the conference button and listen for dial tone (party "A" is now on hold). The line light will be flashing. Dial the number for party B. The phone will ring in party "B's" office. Party "B" answers the phone. The conference is announced to party B. Press conference button again and all three parties are connected. You will hear a confirmation beep when a party is added to the conference. Repeat the steps until all parties are added.
